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

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 ...
1979 – Pioneer 11 flies by Saturn, providing the first ever closeup images of the planet and its rings. It discovers the planet's F ring and determines that its moon Titan has a thick atmosphere. [199] 1979 – Goldreich and Tremaine postulate that Saturn's F ring is maintained by shepherd moons, a prediction that would be confirmed by ...
View of Saturn from Cassini, taken in March 2004, shortly before the spacecraft's orbital insertion in July 2004. This article provides a timeline of the Cassini–Huygens mission (commonly called Cassini). Cassini was a collaboration between the United States' NASA, the European Space Agency ("ESA"), and the Italian Space Agency ("ASI") to send a probe to study the Saturnian system, including ...
