Algodoo

A huge model of the solar system encompassing thousands of kilometers in Algodoo. I have tried to add as many objects as possible and will continue to add them as time progresses. You can either fly to each planet, which takes a while, or you can use the dedicated teleporters to get you around easier (right of this textbox). As of writing (Sep 5, 2026, 20:05 UTC), I have added the eight major IAU recognized planets, their planetary mass satellites, the four largest asteroids, and the dwarf planet Pluto along with its partner Charon. Future additions to satellite systems, the Asteroid Belt, and the Kuiper Belt will soon arrive. Thank you for visiting!

Scale is 1:1,000,000. The Earth is 12.742 meters in diameter and one astronomical unit is approximately 149,598 meters or 149.6 kilometers.

P.S. You can move around with the white box using arrow keys. If you prefer, you can always change it to WASD or any other combination instead, since entering a public Algodoo simulation creates a version specifically for you without changing the original download.

Copy of this same text is in the simulation as well!
