Rhea is the second largest moon of Saturn, behind Titan, and the largest without an atmosphere. It is composed mostly of water ice, but has a small rocky core. Rhea’s rotation and orbit are locked together (just like Earth’s Moon) so that one side always faces Saturn.
What are the 5 largest moons of Saturn?

What is the third largest moon of Saturn?
Saturn’s third largest moon, Iapetus has a mean radius of 457 miles (736 kilometers) and a density only 1.2 times that of liquid water. It has been suggested that Iapetus (like Rhea) is three quarters ice and one quarter rock.
What are the 6 moons orbiting Saturn?

Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
Can you land on Saturn?
As a gas giant, Saturn doesn’t have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn’t be able to fly through unscathed either.
Which planet or moon could we live on?
In the Solar System
|Enceladus||Saturn||Enceladus – potential habitability|
|Titan||Saturn||Colonization of Titan|
|Callisto||Jupiter||Callisto – potential habitability|
|Ganymede||Jupiter||Ganymede – Subsurface oceans|
