A clearer view of space.
Explore 82 objects, from Mercury to Voyager 1, placed with data from NASA JPL and CelesTrak. Free, in your browser.
01 · Scale
The solar system, to scale.
Every orbit is drawn from JPL planetary elements, and every planet sits where it is right now. Nothing is placed by hand.
02 · Worlds
Every world, up close.

18 spacecraft, wherever they are.
From Parker Solar Probe grazing the Sun to Voyager 1 in interstellar space. Each position comes from JPL Horizons and carries its epoch.
- Voyager 1 NASA · Farthest human-made object, in interstellar space since 2012 171.9AU Light from the Sun: 23 h 49 min
- James Webb Space Telescope NASA / ESA / CSA · Earth-Sun L2 halo orbit, since 2022 1.01AU Light from the Sun: 8 min 25 s
- Parker Solar Probe NASA · Closest spacecraft to the Sun in history 0.62AU Light from the Sun: 5 min 9 s
- Europa Clipper NASA · En route to Jupiter system, arrival 2030 0.90AU Light from the Sun: 7 min 29 s
05 · Time
Move through 250 years.
Scrub from 1800 to 2050 and watch the planets move along their real orbits. Pause, rewind, or run a year in seconds.
06 · Sources
Built on public data.
Positions, orbits and schedules come from the agencies and catalogs that publish them. Every object in the explorer cites its source and the date of its data.
