The outer atmosphere is generally bland and lacking in contrast, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 kilometres per hour (1,100 miles per hour). The planet has a bright and extensive system of rings, composed mainly of ice particles, with a smaller amount of rocky debris and dust.
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 features.
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 ...
Saturn doesn't have any easily visible landmarks to track, and its gassy atmosphere doesn't offer many hints as to how fast it's actually rotating. On top of that, its magnetic field also hides ...
Moons have come to exist around most planets and many other Solar System bodies. These natural satellites originated by one of three possible mechanisms: Co-formation from a circumplanetary disc (only in the cases of the giant planets); Formation from impact debris (given a large enough impact at a shallow angle); and; Capture of a passing object.
Astronomers have detected more evidence that Saturn’s moon Enceladus may be one of the most promising places to search for life beyond Earth. Life may have everything it needs to exist on Saturn ...
Saturn – sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth . [ 1 ] [ 2 ] Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive.
Titan’s surface has a temperature of minus 290 degrees, experts say. Clouds and ‘seasonal weather’ exist on Saturn’s ‘Earthlike’ moon Titan, NASA says Skip to main content
