True-distance walk · linear scale, scroll to explore
Distances are true-to-scale (~170px per AU) and reflect each body's real current distance from the Sun, not a fixed average. Planet sizes still use the boost above; at true 1:1 size every planet would be sub-pixel.
Size comparison · one true linear scale, no boosting
The Sun's slot is deliberately wide so its curved edge is visible — at this scale its full circle would be about 1,590px across, far wider than any screen. Everything else here is sized by the exact same scale factor.

Moon size comparison · one true linear scale, no boosting
Genuinely irregular moons (Phobos, Deimos, Proteus, and Pluto's four small moons) are drawn as their real measured shape; every other moon here is large enough for its own gravity to have pulled it into a true sphere.
