Solar System to Scale: See the Real Distances

Every poster of the solar system you've ever seen is lying to you. The planets look evenly spaced and roughly similar in size. In reality, the distances are so vast and the sizes so varied that it's impossible to show both accurately in a single image. The Earth is a grain of sand next to the Sun, and Neptune is absurdly far away.

Two modes, one truth

The solar system scale model has two toggle modes. In distance mode, the planets are placed at their real relative distances from the Sun. You'll need to zoom and scroll because the inner planets are clustered near the Sun while the outer planets are spread across enormous space. The emptiness is the point — space is mostly empty.

In size mode, the planets are shown at their real relative sizes. Jupiter dwarfs everything else. Earth and Venus are nearly identical dots. Mercury is tiny. The Sun, if fully shown, wouldn't fit on your screen.

You can't show both at once because the scales are incompatible. If the planets were drawn at their real size at real distance, they'd be invisible specks. This tool makes that tradeoff explicit by letting you switch.

Putting it in perspective

The distance from Earth to the Sun is about 150 million kilometers (1 AU). Neptune is about 30 AU from the Sun — thirty times farther. Pluto, at its average distance, is about 40 AU. When you see those numbers visualized with proper proportions, the sheer scale of the solar system hits differently than reading it in a textbook.

The solar system scale model pairs well with the planet comparator, which gives you the detailed numbers for any planet you want to dig into.
