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 ...
Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [5] about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
Rhea is the second largest moon of Saturn, but with a mean diameter of 1,528 kilometers (949 miles) it is less than a third the radius of Saturn's largest moon, Titan. Rhea is an icy body with a density of about 1.236 g/cm 3. This low density indicates that it is made of ~25% rock (density ~3.25 g/cm 3) and ~75% water ice (density ~0.93 g/cm 3).
A famous illustration of Saturn's moon Titan got it all wrong. ... This is a world of hydrocarbon seas and vistas of sand and icy rocks. The cold — minus-274 degrees Farenheit — is perhaps the ...
A deep ocean exists beneath the icy, cratered surface of Saturn’s moon Mimas, according to a new analysis of data from NASA’s Cassini mission.
Saturn’s Moon Mimas, known as the “Death Star”, has revealed a new secret.. A “remarkably young” ocean appears to be hiding under the icy, cratered surface of the world that led to it ...
Icy moons warmed by tides may be the most common type of celestial body in the galaxy to have liquid water, [3] and thus the most likely type of object to possibly have water-based life. Some icy moons exhibit cryovolcanism, as well as geysers. The best studied example is Saturn's Enceladus.
Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn subtends an arc of 5.09 degrees, and if it were visible through the moon's thick atmosphere, it would appear 11.4 times larger in the sky, in diameter, than the Moon from Earth, which subtends 0.48° of arc.
