Ceres
The largest body of the asteroid belt and the only inner-system dwarf planet — the first dwarf planet ever orbited (Dawn, 2015).
- Mean distance
- 2.77 au
- Orbital period
- 4.6 y
- Diameter
- 939 km
- Mass
- 0.001 ×10²⁴ kg
- Known moons
- 0 (as recorded)
Values: NASA Planetary Fact Sheet · NASA Solar System Exploration — not network-verified in this run.
Listed without a figure position: JPL small-body orbital elements were not importable in this environment, and no position is invented.
Recorded encounters
- 2015 DawnDawn enters orbit around Ceres — the first dwarf planet orbited
An encounter sequence is the order the records give, not a flight path. Atlas holds no trajectory for these missions and draws none.

Schematic view: distances are log-compressed (to true scale Neptune sits 30× Earth’s distance) and discs are ranked by size, not to scale. Positions computed from JPL mean orbital elements for today — an orientation good to a few degrees, not an ephemeris.
