The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Galileo also discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it. [13] Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14]
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
The name of Eris's moon Dysnomia was suggested by its discoverer Michael E. Brown, ... or "S/2003 S 1" (the 1st new satellite of Saturn discovered in 2003).

[199] 1979 – Goldreich and Tremaine postulate that Saturn's F ring is maintained by shepherd moons, a prediction that would be confirmed by ...
Pioneer 11 image of Saturn.. Saturn was first visited by Pioneer 11 in September 1979. It flew within 20,000 kilometres (12,000 mi) of the top of the planet's cloud layer. Low-resolution images were acquired of the planet and a few of its moons; the resolution of the images was not good enough to discern surface featu
December 15 – Janus, one of the moons of Saturn, is identified by Audouin Dollfus (it had been first photographed on October 29). [2] December 18 – Epimetheus, another of the moons of Saturn, is discovered, but mistaken for Janus which shares its orbit and they are not distinguished until 1978. Mullard Space Science Laboratory established ...
