The whole solar system in your browser, from the orbit of Pluto down to the surfaces of planets, moons and asteroids. No game, no passphrase. Just the real place, rendered from the data humanity has gathered.
01 · Atlas
Real orbits, at real scale
The Atlas is the map everything hangs off. Planets on JPL approximate positions, moons on JPL Horizons fits, and the points between them that physics cares about.
- Lagrange points for Sol-Earth, Sol-Mars, Sol-Jupiter and Earth-Luna.
- Barycenters, including Sol-Jupiter: Jupiter is massive enough to orbit a point outside the Sun.
- Real satellites from an October 3 snapshot, color-coded: crewed stations, observatories, navigation, communications.
- Timelapse at up to one day per second, with belts and moon-orbit spirals you can toggle.
02 · Bodies
Every body from real imagery
37 tracked bodies. The imagery comes from the missions that took it.
03 · Surfaces
From orbit to the ground
Descend through the atmosphere and walk the terrain at sites humanity has mapped in detail.
04 · Light
Eclipses, sunsets, and real shadows
Light is simulated, not painted. Shadows fall between bodies, eclipses happen when the geometry says they do, and the Sun is white in space and reddened through air.
- Europa eclipse. The small black dot crossing Jupiter's face is Europa's shadow, spotted in the sim and confirmed.
- Body shadows checked against the real November 8, 2022 lunar eclipse.
- No air, no twilight. Lunar night lasts about fifteen Earth days; night vision amplifies exposure about 12x.
