Almost every picture of the solar system lies. To fit on a page, the planets are squeezed together and blown up in size. Walk it at true scale and you discover the real star of the show: empty space.
The solar system is mostly empty space, and that emptiness is the whole story.
Look
Most pictures of the solar system squeeze the planets together like beads on a string, and draw them far too big. They have to: at true scale, a page would be almost completely empty.
Guess first: if the Sun were a beach ball, how far away would Earth be? A step? A room? A street?
A street. With the Sun as a 1-metre ball, Earth is a 9 mm pea about 107 metres away: roughly the length of a football pitch. Keep that picture in mind as you travel.
The Scale Walk above is drawn at true scale: sizes and distances in the same proportion. Every pixel you scroll carries you 3,000 km. Scroll inside the frame, press Next world, or tap a planet on the journey map at the top.
- The journey map is to scale too. The white marker is you. Notice how the Sun and the four inner planets crowd together at the far left.
- The odometer counts kilometres and the time sunlight has needed to get where you are.
- When you stop near a world, the camera locks on and leans in (the zoom is shown next to the scale bar), and a card tells you where you are.
- Earth, a globe 12,742 km across, is almost 50,000 scrolled pixels from the Sun. Neptune is about 1.5 million pixels away.
Notice how much of the trip is just black, with only a few lines of narration drifting past. That is the real solar system: tiny worlds separated by enormous emptiness.
Understand
A scale model divides every length by the same number. Here the number is 3,000: 3,000 km of real space becomes 1 pixel.
| World | Real diameter | Diameter at 1 px = 3,000 km | Distance from Sun | At this scale |
|---|---|---|---|---|
| Sun | 1,391,400 km | 464 px | 0 | 0 |
| Earth | 12,742 km | 4 px | 149.6 million km | 49,866 px |
| Jupiter | 139,822 km | 47 px | 778.3 million km | 259,437 px |
| Neptune | 49,244 km | 16 px | 4,498 million km | 1,499,000 px |
A handy comparison uses the Sun as a 1-metre ball. Divide everything by the Sun’s diameter (1.39 million km):
- Earth is a 9 mm pea, 107 m away.
- Jupiter is a 10 cm grapefruit, 560 m away.
- Neptune is a 3.5 cm marble, 3.2 km away.
- The nearest star, Proxima Centauri, would be another ball about 29,000 km away: more than two thirds of the way around the real Earth.
Try the autopilot at 1×, the real speed of light. You move 100 pixels per second, which feels slow on screen. Real sunlight really does need 8 minutes to reach Earth and more than 4 hours to reach Neptune. The faster settings compress time, not distance: the autopilot still brakes and pauses at every world.
Guess first: scrolling with a mouse wheel, are you moving faster or slower than light?
Much faster. A brisk scroll carries you millions of kilometres per second, often ten or more times the speed of light; the speed readout under the odometer shows it. Even so, the outer planets take a long time to reach. That is how big the distances are.
Master
Two separate compressions distort normal diagrams: the size scale and the distance scale. The ratio of the Sun-Neptune distance (4.5 × 10⁹ km) to Earth’s diameter (1.27 × 10⁴ km) is about 350,000. A screen 1,000 pixels tall can resolve a range of about 1,000, so no single static image can show both the planets and their spacing. Interactive zoom, logarithmic axes or a scroll-length model like this one are the only honest options.
This is also why the orrery on this site offers two modes. Readable scale compresses distance with a square root (r_screen ∝ √r) and draws planets at fixed legible sizes. True scale is linear in both size and distance, so the planets shrink to sub-pixel dots.
The emptiness has consequences for spaceflight. Travelling between planets is not like driving between cities: the planets move, the distances are huge, and the energy cost depends far more on changes of speed than on distance. That idea, delta-v, is at the heart of the Navigator path.
A last scale fact: the asteroid belt, often drawn as a crowded field of rocks, is so sparse that spacecraft cross it without any special manoeuvres. The Kuiper belt beyond Neptune is emptier still.
Ku day
Set the autopilot speed to 1× and press 'Travel at the speed of light'. Watch the light-time clock as you reach Earth: about 8 minutes 20 seconds. Before you look at the table, guess how long the same trip takes to Neptune, then check.
Wayn. Dhibaatooyinka waa halka waxbarashada ku shubto.
Imtixaan degdeg ah
3 su'aalo degdeg ah. Dooro jawaab si aad u aragto haddii aad xaq tahay.
-
If the Sun were a ball 1 metre wide, about how big would Earth be?
- A A football
- B A grapefruit
- C About 9 millimetres, like a pea
- D About 1 millimetre
Tuso jawaabta
C. About 9 millimetres, like a pea The Sun is about 109 times wider than Earth, so 1 m ÷ 109 ≈ 9 mm.
-
At that same scale, how far away would Earth be from the 1-metre Sun?
- A About 1 metre
- B About 10 metres
- C About 107 metres
- D About 1 kilometre
Tuso jawaabta
C. About 107 metres 1 au is about 107.5 Sun diameters, so Earth would be a pea about the length of a football pitch away.
-
Why do most drawings of the solar system show the planets close together?
- A Because they really are close
- B Because at true scale the planets would be too small to see on the page
- C Because the drawings show the planets at their closest approach
- D Because of light pollution
Tuso jawaabta
B. Because at true scale the planets would be too small to see on the page
