Saturn's Moons

Iapetus

Tethys

Titan

Saturn's Moons

Rhea

Dione

These are just five of Saturn's 50+ moons!

Titan is the largest of Saturn's moons. There are lakes and rivers and there is rain on Titan, however it is no water. Titan is very far away from the sun, and it's surface temperature is -179 degrees celcius, therefore all the water on Titan is frozen, and it instead rains liquid methane. The atomsphere of Titan is alot like the atmosphere of early Earth, it is made of mostly nitrogen, methane, and ethane. The Cassini spacecraft was sent to study Saturn along with its moons. This probe may help scientists learn about the beginning of life on Earth. Also, Titan was discovered in 1655 by Christiaan Huygens.

Rhea is Saturn's second largest moon, and it is also the most heavily cratered.The reason that Rhea is most cratered is because it is farther away from Saturn than Dione and Tethys, which causes there to be no internal heating. This means that there was never enough heat to melt the water even a little bit, so it couldn't have filled in the craters. Rhea may also be made of mostly water ice, not rock.Rhea was discovered in 1672 by Giovanni Cassini. The surface temperature of Rhea is -200 degrees celcius.

Tethys is the fifth-largest moon of Saturn. It has low density and a very bright surface, which means that Tethys is actually made from water ice not rock. The crater seen in the picture above is Odysseus, and it takes up about 2/5 of Tethys' size. It's surface temperature is -187 degrees celcius.

Iapetus is the third largest moon of Saturn. Iapetus is a special satellite because it has two differnt colors. Part of Iapetus is extemely dark, but the rest is much, much brighter, and the contrast line is very shap. The temperature of Iapetus is -163 degrees celcius. Giovanni Cassini also discoverd this moon in 1671.

Dione is one of the smaller moons of Saturn, but it is still the 15th largest in the solar system. Dione is also made of water ice mostly not rock along with Rhea and Tethys. Also, Dione is heavily cratered and some of the satellites that caused those craters may have cause Doine to rotate. Some scientists say that it may have even been 180 degrees, but no one knows for sure.This is another planet discovered by Giovanni Cassini, and in 1684. It's temperature is approximately -186 degrees celcius.
