Saturn
The ringed giant, orbited for thirteen years by Cassini. Moon count as recorded 2025 — it moves with every survey.
- Mean distance
- 9.537 au
- Orbital period
- 29.457 y
- Diameter

Values: NASA Planetary Fact Sheet · IAU Minor Planet Center announcements — 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
- 1979 Pioneer 11Pioneer 11 passes Saturn — the first spacecraft to reach it
- 1980 Voyager 1Voyager 1 passes Saturn and Titan, and leaves the plane of the planets
- 1981 Voyager 2Voyager 2 passes Saturn and continues towards Uranus
- 2004 Cassini–HuygensCassini enters orbit around Saturn
An encounter sequence is the order the records give, not a flight path. Atlas holds no trajectory for these missions and draws none.

Schematic · log-compressed · ranked discs · not an ephemeris — full statement →
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.
