It is estimated that the A Ring contains 7,000–8,000 propellers larger than 0.8 km in size and millions larger than 0.25 km. [4] In April 2014, NASA scientists reported the possible consolidation of a new moon within the A Ring, implying that Saturn's present moons may have formed in a similar process in the past when Saturn's ring system was ...
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
Scientists finally have a comprehensive view of Titan, Saturn's largest moon. A team of astronomers has created the first global map of Titan by using the Cassini probe's over 100 fly-bys to ...
The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 450–500 km radius may be quite porous. [10] For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere.
Explore all 63 of Saturn's verified moons, along with their names and discovery dates. Other moons await official confirmation of their discovery.

The actual semi-major axis differs by 19 km, and the actual mass is 8.6 × 10 −12 of Saturn's. The moon was later found within 1° of the predicted position. The search was undertaken by considering all Voyager 2 images and using a computer calculation to predict whether the moon would be visible under sufficiently favorable conditions in ...
