A Tediously Accurate Map of the Solar System

moonpixel2

I was talking about the planets with my 5-year-old daughter the other day. I was trying to explain how taking a summer vacation to Mars in the future will be a much bigger undertaking than a trip to Palm Springs (though equally as hot). I kept trying to describe the distance using metaphors like “if the earth was the size of a golf ball, then Mars would be across the soccer field” etc., but I realized I didn’t really know much about these distances, besides the fact that they were really large and hard to understand. Pictures in books, planetarium models, even telescopes are pretty misleading when it comes to judging just how big the universe can be. Are we doing ourselves a disservice by ignoring all the emptiness?

So I thought I would see if a computer screen could help make a map of a solar system that’s a bit more accurate (while teaching myself a few things about javascript, SVGs and viewports along the way).

Not that pixels are any better at representing scale than golfballs, but they’re our main way of interpreting most information these days, so why not the solar system?

    On Chrome, the scroll is too fast to read the bits of writing between the planets. I see some sentences flashing by, but that’s it!

    I’m on Chromium Version 32.0.1700.107 Ubuntu 13.10 (32.0.1700.107-0ubuntu0.13.10.1~20140204.972.1)

      Did you try holding down the right arrow on the scroll bar? I use Chrome too and that worked much better for me.

    • Davey July 13, 2016 at 9:21 pm - Reply

      The best way is to click the middle mouse button. Then the scroll speed is variable based on the distqance of your mouse to that anchor point.

    Thanks for this, a really cool piece of web programming! PZ Myers linked it recently on Pharyngula, which resulted in it getting eyeballed by a few people with pretensions to being astronomers. (And some of us are really pedantic assholes – me included! – so I apologise for noting that the appearance of the Jovian satellites immediately struck me as wrong; also please forgive me for compiling the following list of what are essentially, nitpicks.) That said, I do actually like the snarky comments interspersing the inherent tedium of accurately depicting the distances between the planets to scale!

    1. In the scale legend, the normal SI abbreviation for the metre should be shown as the lower-case m, not M.

    2. The spacing of the Galilean satellites have been perturbed; the three beyond Io are 121 pixels too far to the right (exactly the amount of the apparent width of Io’s orbit). The quantities 193, 307, and 541 pixels would be correct if you hadn’t already shifted the moons to start with, 121 pixels beyond Jupiter; as it stands if Io is at ‘0’ px, then E, G, and C should be at corrected distances of 72, 186, and 420 px. The reason this immediately stood out to me as not-quite-right is a well-known, fascinating feature of the Jovian satellites – Io, Europa, and Ganymede are in gravitational resonance with each other, with their orbital periods almost exactly in a 1:2:4 ratio; Kepler’s harmonic law also relates this ratio to the semi-major axes of their orbits, 1:∛2²:∛4². Callisto spoils the pattern somewhat – it’s in a ~9.4:4 ratio with Ganymede, rather than the 2:1 resonance.

    3. Triton, Neptune’s giant moon is omitted, despite being well over half the diameter of the earth’s moon – and larger than Pluto! If a moon being smaller than the earth’s moon was the only criterion for non-inclusion then you would have lost Europa as well; and Triton is rather close-in to Neptune at only 102 px. Like Europa, Triton is closer to being rounded up to 1 pixel in size (whereas all of the other moons and minor planets in the solar system are closer to being rounded down to zero).

    4. Eris has been measured (radiometric and occultation measurements) at almost exactly the same size (Wikipedia: 2326 ±12 km) as Pluto (2306 ±20 km)… why no love for (dwarf) planet X as well? And it would only add another 2.45 million pixels(!) further on to depict its current position 96.4 astronomical units from the sun… lol. (None of the other TNOs/dwarf planets currently known have a mean diameter greater than the moon’s radius.)

    5. Having the astronomical symbols for the sun and planets to click on to automate the scrolling is a very nice feature that didn’t appear on my mobile phone; given that Pluto is 5.5 light hours from the sun, it’s nice that scrolling the entire width of the page via click only takes 5 seconds or so – that seems like an apparent speed of 4000 times the speed of light! So I imagine it might be possible to code the rate of change in the scroll location (measured in km) as a multiplicative factor of light speed…

    Not a nitpick as such, but even a linear display such as this is implicitly ignoring two of the three spatial dimensions; to imagine a blob of 1 px in size representing say Pluto or the earth’s moon without scroll bars, you would need a 2D computer display of about 4 million pixels in each direction – say sixteen trillion (1.6×10¹³) pixels screen area – and then have to have some way of cubing that to a 3D model multiplying that number by another 4 million… and of those approximately 10 to the power of 20 pixels, only about 70 million would be non-black (the vast majority being those depicting the Sun).

    Space is mind-bogglingly empty – though as other people have noted, if a similar graphical method were used to compare the size of an atomic nucleus to the surrounding electron cloud, the resulting display would be even larger and comparatively empty.

    Finally, thanks again for doing this. Thumbs up!

      Thanks for all the great insights! I had a feeling it wouldn’t quite pass the true astronomer test. Pluto is only visible for sentimental reasons, which don’t quite mesh with actual science. I originally wasn’t going to include any moons besides ours, but then I got carried away and started adding them without really finishing. I’ll use all your notes when I revisit it. Thanks again!

    Awesome site!
    Just took a tour on our Solar System. Very tired.
    But can you please add a few more features?

    For starters, please add an “auto” button so one doesn’t have to keep
    holding the left mouse to scroll the bar. Just click auto and let it go.

    Secondly, could you add a little rocket ship at the bottom?
    Like, right above the kilometer meter? It would give the representation
    a nice touch I think. Also animate it with the little flame behind the rocket and stuff like that. Plus, make the ship slow down during the text parts,
    so like if you are in “auto” mode and the rocket is moving… slow it down so we can read the text and then speed it up again during the black boring parts.

    Lastly, add an amount of how many pixels make up a planet.
    You mentioned that the moon is 1 pixel, but what about the sun?
    or the earth, or even Jupiter being the giant it is.
    So when you see, say, Jupiter, it tells you how many pixels compose it.

    Just a few pointers. Great representation tho. Made it all the way to the end lol

      When you look at it on a desktop browser, there’s a distance counter near the bottom and some shortcut astronomical symbols at the top. Still can’t figure it out!

    It was a great spiritual experience. Thanks for making this. Please dont ever, ever take down the page.

    Many sages and siddhas have written many poems in Tamil explaining the significance of this emptiness. They claim it is the same emptiness that exists between the planets, exist between electrons of an atom.
    Mother bears a child, here who is stronger and has more weight ? Mother or the child ? Obviously, the mother is stronger. And similarly this wast nothingness bears all these planets, even though it is nothing, it is much stronger and has more weight than the sum of all things in this universe.

    When we swim in an ocean, the ocean holds us. Its much bigger than us. We are just traversing through it. When we stroke and advance a bit, the ocean fills the spot where we were a moment before. Its always there.

    Similarly this nothingness is always there. The atoms that make the cells, cells that make the molecules, molecules that make organs, organs that make us have this nothingness within much in the same way the nothingness that exists between two planets. So by this analogy, you can safely say, the nothingness that exist between Pluto and Neptune already exist between two electron of an atom in your brain cell.

    So they say, if one needs to understand the concepts of universe, one doesn’t have to look outside, one can start looking inside. Both are hard, but looking inside is a bit easier than looking outside.

      Some beautiful, wise words. If you ever decide to start a cult, you can count me in!
      Not sure if I agree that looking in is easier than looking out. If you’re looking within and you stumble on a black hole, you’ll get sucked in for real!

    I loved taking Astronomy when I was in high school and this would have been really helpful! I think you were able to capture the distance between everything fairly well. While I still can’t fathom the size of our universe (let alone the size of our Solar System) this made it a bit more understandable.

    All that emptiness is calming and reassuring in some way. When petty everyday things start to annoy, remembering how tiny we are in all that vastness will help.

      I also want to say that it consistently scales itself to be slightly taller than the window, meaning that there’s always a tiny amount of vertical scroll.

      Depends on the resolution. If it’s 300 dpi, and the sun (which is 400px on screen) is as tall as the paper, it works out to be 46,777″ wide (3,898′) or 5503 sheets of paper! That’s a lot, but doesn’t seem quite right. Someone please check my math.

    Pretty cool! I liked the comments, and holding down the scroll bar makes you understand just how much space there is…really, if it automatically scrolled to the next planet, well, you might as well get a bedroom solar system mobile. The original Whole Earth Catalog had projects teachers could do to help their students understand space and the solar system; use a roll of toilet paper and mark the planets on it; find household items like grapefruit and raisins to be planets and place them in a field, or use homemade signs along a road – sometimes your solar system stretches for miles! I did a roadside one when my kids were in school learning about the solar system. Now I want to do one of an atom! Yahoo! Many thanks, this was a blast.

    Had a singularly challenging, empty day, feeling like nothing. Scrolling all the way through this gave me perspective. And how amazing that the emptiness of space echoes the emptiness inside an atom, and actually inside our bodies, too, when you think that our atoms don’t touch. If this is the pattern, then it stands to reason that experiences of emptiness in the spirit holds significance as well. The emptiness gives weight to what IS there, making it significant. Wow.

    Thank you, Josh – you sure made a difference in my day today.

    And THANK YOU for adding Pluto – yes, we still love it!

    Amazing! Just when one might’ve thought “scale of the universe” visualizations were old hat, you’ve gone and created something startling and fresh. Very nice work. 😀

    I just wanted to point out that it’d be worth your while to fix the CSS bug that’s causing your page to scroll vertically (consistent in Chrome/FF/IE, even with the page full screened at 1920×1080). “body { overflow-y: hidden; }” would be a (hacky) one-line fix, but I believe the real problem may be your use of “vh” for div dimensions.

    Very impressive! If you’re willing to take any suggestions, I was thinking that a small window in the top, right corner (3″ X 3″ perhaps) could show the receding sun as you head toward Pluto, starting out at full size and getting proportionally smaller as would be seen by the time you get to each planet. Just a thought.

      • Asa March 10, 2014 at 10:33 pm - Reply

        This is great!
        I actually had a similar idea to the rearview mirror that it would be nice to keep things in a perspective view of some kind (until they would disappear anyway). What came to mind for me was putting the whole trip more on the y axis than the x axis,.. and like we’re looking through the rear window of our vehicle the whole time. Maybe a dual-viewport set of forward-looking and backward looking views would further aid perspective awareness. E.g., (backwards) The sun would always be in view. Maybe at a minimal x angle so the planets don’t overlap each other, assuming that more than one would would ever require a pixel at a time. P.S. In Firefox 29 Aurora (only browser tested), I have vertical scroll bars, in the event the fix you mentioned in a comment should already be in effect. I took the trip in 1920×1080 fullscreen.

        Thanks! Will be sharing.

    This is a great applet and I sent it out to a group of middle school science teachers to (hopefully) explore with their students.
    That said, I have a question, and I mean no disrespect.
    Would it be much more difficult to replace the larger planets with actual images? It would be nice, after all that scrolling, to get a 2D picture of Jupiter rather than an orange circle. There’s some readily available in the wikimedia commons. I know they’re pretty big but you could shrink them with your skills.
    you could set up an html/xml tag

    and then set up a css selector for it that could shrink it

    #jupiter {

    position: absolute;
    top: 0;
    left: 25%;
    height: 100px;
    width: 100px;
    margin-left: -25px;
    margin-top: -25px;

    –I just put in arbitrary numbers here. I can see you used XML now that I’ve looked. Anyway, thanks for the page!

    Hey man, great job. I’ve seen something similar before but it didn’t have the ruler at the bottom (the screen was full of stars which passed by instead). The ruler gives a much clearer sense of distance. Just a tip: would be better if the comments just appeared static momentarily perhaps at the top below the symbols instead of passing by. I can’t read them as it scrolls so I have to stop the scrolling to read them which kills the association between time duration of scroll and distance. Other than that, great stuff.

    Loved it, Josh. Quite an abbreviated trip! Fabulous ‘billboards’ along the way. So, size is relative. And matter, just like the universe, is also incredibly ’empty’. The following example has shown up in many places, one being on physics.org, that because of all the space inside each of our atoms, the entire human race could fit into the volume of a sugar cube. So much space Everywhere. Thanks for putting your map out in cyber space!

    I was thinking about what would be a good model to show the scale of the universe in the web just two days ago. The thought came up right after I woke up and realized that I had probably been re-living in a dream an actual day in 1985 in high school when we imagined a model. In our model, the pixel was the head of a head pin located in the middle of our school patio. For me it was an aha moment.
    Thank you.

    Though I once believed investing in space was like investing in our future for knowledge and expansion, eye-opening exhibits like this reinforce what I now believe— the universe is just too big for exploration. Pretty disappointed in mankind that almost 50 years from landing on the moon that are crowning space-related achievements are getting benefits from man-made satellites (ie gps), stationary telescopes (ie Hubble), and moving telescopes (probes— but I am excited about New Horizons approaching Pluto next year). Things are too far so focus in subjects that affect us more like medicine.

    My significant other just said, “My right arrow is faster than the speed of light.” Just… wow. As if this project wasn’t already mind blowing.

    It would be cool to see a version where holding the right arrow/scroll button makes the model move at the scale speed of light. So for instance, holding the right arrow leaving the sun, you arrive at Mercury after 3 minutes 12 seconds.

    Nobody would last much past Earth, I’ll bet. Still, it would make you stop and realize the crazy scale.

    Very nice. Strikes me though a single 32 bit integer can count the km well past Uranus. So your 64 bit computer is pretty darned big on the inside too. A single word can count well more integers than the km to Pluto (we still love you!) — where would you end up in space at 2^64 km… past Alpha Centauri …

    Fun, and a nice capture of “size.” A local school built a solar system and installed it on the bike path – the inner planets were done and gone before you got off the starting part; the last planet was10 km away !

    “km” as a unit of measurement is a bit messy – perhaps using the “light second” as a basis would help connect this to the astronomical realm.
    (The earth being about 500 light seconds from the sun, etc…)

    Anyway, thanks

    There should be a PixelMoon Fountation for the enhancement of the project, like: add right-click pop-up explanations about bodies encountered, 3d representations, meteors position (remember the ISON crazyness some time ago?), trip to the Oort cloud, and so on…

    And: could there be an off-line application, to be seen without an internet connection?

    This is the best thing I’ve seen in a long time. I realized that I’ve never actually seen a true scale of our solar system before and it is simply epic.
    I love that in the beginning, the notes were playful jabs about the amount nothingness but as I scrolled further out, the notes became progressively profound and border-line philosophical. Especially the bit about being both pathetically insignificant and miraculously important. Wow.
    Excellent job. I look forward to more of your interactive work.

    Thanks for making this. I was specifically looking for a to-scale model of the solar system when I came here, and this is exactly what I was looking for–and absolutely fascinating. One of my ‘pet peeves’ with the way the solar system is depicted on TV is that they always show the planets and moons far too close together (and/or far too large) and the inaccuracy was bothering me. (Even documentaries on astronomy such as “The Universe” do it.) Now I have more of an understanding why they do that!

    Minor quibbles: I would’ve liked to have seen a few more of Jupiter and Saturn’s moons, and maybe little Ceres could put in an appearance, midway between Mars and Jupiter? I was actually a little disappointed that you stopped at Pluto and didn’t go on to cover some of the more recently discovered transplutonian objects such as Eris, Haumea, Quaoar, Makemake and Sedna. Then again, Sedna takes 11,400 years to orbit the Sun, and at its closest point it’s about twice as far out as Pluto (at its furthest, it’s over 900AU away, 30 times the distance to Neptune), so that’s a whole other lot of additional nothingness, and I think the point has already been made.

    I also enjoyed the commentary, it helped to evoke an appropriate frame of mind–the human brain just simply isn’t built to grok distances of more than a few hundred miles, and we are orders of magnitude out of our depth here. Light travels at an alarmingly slow rate on these scales.

    This is the best of these I have seen. The scale on the bottom helps a lot. Others don’t include this and so you don’t know if the system is not working or if ithe next planet is still far away. Or they put pretty little stars between the planets which is a major misconception!
    The humor helps a lot; always a great teaching tool.
    One complaint or should I say wish:… most of us in the U.S. of A don’t know metric. Can you add miles?

    I think what amazes MY primitive mind so much is that you have to go way past Saturn to even get half way across the solar system. I would instinctively think it was the asteroid belt or even Jupiter. I would have easily understood Saturn as the midway point. But you have to almost reach Uranus to get midway to your destination.

    Unbelievable.

    BUT, THERE IS A SERIOUS OMISSION!!! TRITON, THE BIG MOON OF NEPTUNE.

    Triton is larger than Pluto! Triton is 2706km in diameter; Pluto is 2370km.

    Triton also represents a big cut-off when it comes to moon size. The first 7 moons get gradually smaller (Ganymede 5262km, Titan 5150km – both bigger than Mercury 4880km – Callisto 4806km, Io 3642km, Moon 3476km, Europa 3138km, Triton 2706km), and then there is a big jump to Titania at 1580km – less than half our Moon’s diameter.

    Finally, Triton’s is more massive than all the moons in the Solar System smaller than itself combined. So there is a big cut-off.

    (I have a minor quibble about Eris, but that would nearly triple the width of you picture!)

    I took the time and scrolled all the way through to Pluto, and although I got impatient and tried to move through faster, it did help me somewhat understand the vastness of space.
    I did also enjoy the text comments throughout, but something bothered me. The ending text says that the universe “seems to value” the little blips (including us) along with the big empty spaces. However the universe is expanding, meaning the empty space is getting bigger- which includes the space in our solar system. Yes, this expansion is slow, relative to our sense of time, and not as significant on a smaller scale like our solar system (as compared to galaxy clusters), but over time everything in space is moving away from everything else. I didn’t see anyone else mention this and I thought it should be taken into consideration.
    Otherwise, I throughly enjoyed the project and appreciate all the work that went into it.

      Very good point about the expansion of space. So much to consider when considering nothing.

  87. Stephen Fish August 18, 2015 at 11:48 pm - Reply

    Empty Space? – I prefer to think of it as Solid Dark, if you start to think of the nothing as something then it changes the way we think (and see). The only thing faster than the speed of light is the speed of Dark. Dark always beats light in the race. Dark is filling my quantum cat’s box before it switches on it’s tiny torch. Dark fills the box instantly when the battery has gone. Dark isn’t bothered or interested in time either, and it probably doesn’t reflect on things much. I guess it was there at the beginning before light even set off? If there is so much of it though – how can we even see any light?. The weirdest thing is, you can easily look through a massive portion of Dark (as your excellent site shows) and still see Jupiter with the naked eye: so I wonder, is light going through Dark cleanly in this scenario and moving Dark to one side (making the dark either side even DARKER?!), or is Dark just chasing the light like a rabid Pacman eating photons, or is it simply accommodating where the light will be across the entire universe, like an electron accommodating a change in excitement? (temperature). Maybe that’s what dark energy is?

    Hmm, I think I am on to something…

    Lights not all it’s cracked up to be either, we seem overly obsessed with it. If these weird photon~wavey doofers hit my eye at different wavelengths to make an image, where does the photon~wavey doofer go? and don’t say it reflects, because if that was the case – could someone else see what I was looking at, then look at someone else over and over and send it back ad-infinitum – or would they see the back of my eye. I tried this whilst looking at Jupiter, and the missus said she could only see the darkness.It was night time, but I guess the Dark could also have chased it and sucked it up like my pacman-esque theory above. Oh, and – the damn cat in the box wants to know why dark won over all the photon~wavey doofers it emitted from his torch. I know he’s purely observational, but that’s part of his problem right now…If I pass him new batteries through a light-proof hatch, will he still be alive?

    So scientists and problem solvers alike, stop trying to work out how far away something is and how we get there faster, and work out instead how to use Dark to our advantage. Dark drives, FTD, and anti-lasers. The future is not so bright after all…

    Brilliant piece of design and code BTW <3

    Will you ever do an 8×8 pixel version, or one where you can change the Solid Dark to blue or a rainbow gradient? Just to see if it makes it easier to comprehend? I mean if there was ever a call for a rainbow gradient, this would be it. I can't think of any other reason for a rainbow gradients existence…Do you think dark has a spectrum? Oh god what have I done….

      Oh my. You’re definitely on to something. I like this idea that thinking of emptiness as something actually turns it into something. Just give it a name and you can start to track its behavior like a character in a story. The stuff of language and the stuff of physics are weirdly intertwined. Thanks for the enjoyable thoughts.

    And man’s finite mind cannot imagine the infinity of space. We must conjure up some way for it to have an end, and devise mathematics to prove that, if we go far enough, we’ll return to where we started.

    Everyone else has already covered the appreciation I feel for this site. But a couple of things happened as my wife and I scrolled right that I thought I’d throw into the pool.

    First I looked at dot Earth, then scrolled to dot Mars, and I thought of thus nano-subpixel vehicles, starting with Mariner, then Viking, Pathfinder, etc that attempted to, and, finally, did find their way across that vast emptiness to their land on their target. Unbelievable. And then there’s Voyager – now out there in interstellar space. Somehow this site brings into focus the enormity of man’s achievement, the incredible power of the biological phenomenon called intelligence. It would be interesting to somehow include the size of the human brain in this perspective exercise. What fraction of a pixel would a brain be? Your insightful comments on our incapacity to handle the concept of emptiness need to be balanced by a treatise on the extraordinary capacity of the human brain, well some of them anyway, to figure so much of the universe out. I don’t think I have ever seen this quite so clearly till tonight.

    The second thing that happened: about when we got to Saturn, my wife got up and left the room. “I can’t take any more – this terrifies me”, she said.
