Saturn is the crown jewel of the solar system, beautiful and fascinating. It is a gas giant, and has a broad set of rings made of ice particles. Moons create gaps in the rings via their gravity. Saturn has dozens of moons, including Titan, which is as big as Mercury and has a thick atmosphere and lakes of methane; and Enceladus which has an undersurface ocean and eruptions of water geysers. While we are still uncertain, it is entirely possible that either or both moons may support life.

As someone from Philly, every time I hear "water ice" I assume we are talking about the dessert.

Sam Hanson says:

good video but I came here for a hexagon explanation, never got one 😔

CrazyeyesDark says:

Mhm, Saturn and its rings did initially capture my interest in astronomy, I can confirm that. Now I hate those rings with a passion. I will be writing an astronomy exam today, in about four hours or so, and I am utterly overwhelmed.

Jose De La Cruz says:

the moons might have life after the sun is a red giant.

DraconicEpic says:

Saturn wouldn't float in water. the core would fall through and the gas would disperse.

Govinda Dasu says:

have to look at saturn through a telescope now!

Stuart Hughes says:

I reckon, saturn space rings,,, looks like space auto estrada..

Dan says:

You say Saturn´s rings are 10 meters thick, but wherever I look up that information, I get they are actually 9 km thick. So, what is it?

Momotaz Ali says:
