Moons

Enceladus is a living moon with a vast ocean of liquid salty water under its surface. Furthermore, constant jets of frozen particles from that ocean, loaded with a brew of water and basic organic compounds, erupt into space from this intriguing underwater world. The debris travels at around 800 mph (400 meters per second) and generates a plume that stretches hundreds of kilometers into space. Some of the material returns to Enceladus, while others escape and create Saturn's massive E ring.

Enceladus sprays its ocean into the atmosphere where we can receive a sample. We have come to the conclusion that this moon contains the chemicals that would have life. It also has the most reflective white surface in the solar system. Its icy particles shoot out from the moon and go father out into Saturn's orbit. This moon contains water vapor, carbon dioxide, methane, and a little bit of ammonia. (NASA)

Rhea is Saturn's second-biggest moon, but its average radius of 475 miles is less than a third that of Titan, Saturn's largest moon. Rhea, like her sister moons Dione and Tethys, is a tiny, chilly, airless body. Rhea is tidally locked with Saturn, with one side constantly facing the planet while it completes its 4.5-day cycle around the planet. Rhea's surface temperatures are comparable to those of Dione and Tethys, ranging from -281 degrees Fahrenheit in the sunlight portions to -364 degrees Fahrenheit in the shadowed areas. Rhea, like Dione and Tethys, has a high reflectivity, indicating that its surface is mostly made of water ice. The Cassini spacecraft discovered indications of material circling Rhea in 2008, marking the first time rings were discovered around a moon. A large debris disk and at least one ring appear to have been discovered by a set of six Cassini instruments dedicated to studying the atmospheres and particles around Saturn and its moons. (NASA)

Dione is a tiny moon with a mean radius of 349 miles that circles Saturn every 2.7 days at a distance of 234,500 miles, about the same as the moon orbits the Earth. Dione's density is 1.48 times that of liquid water, implying that a dense core makes up approximately a third of the planet's material, with the rest being ice. Ice is exceedingly hard and acts like a rock at Dione's typical temperature of -304 degrees Fahrenheit. Dione is continually bombarded by very fine ice particles from Saturn's E-ring. Enceladus, which has a lot of geyser activity, is where the dust in the E-ring originates from. Also, Scientists suspect Dione may have a thin Oxygen atmosphere. Dione is a dense rocky core surrounded by ice water. It is heavily cratered however all the craters are on the backside of the moon. It is thought to have a liquid ocean beneath its surface. (NASA)

Hyperion is a very small moon with an irregular shape. It is thought that the irregular shape of the moon is due to a larger moon's collision years ago. Due to Hyperion's low density, it has a spongy surface. Most of the craters are bright which means that they are likely filled with Ice-water. Hyperion is Saturn's biggest irregular, non-spherical moon. Hyperion is most likely a relic of a bigger moon that was destroyed by a catastrophic collision, based on its peculiar form. The density of Hyperion is somewhat higher than that of water. This might be caused to water ice with gaps of more than 40%. Hyperion might also be made out of lighter materials like frozen methane or carbon dioxide. This fits with the idea of Hyperion forming from a collection of smaller ice and rock entities that couldn't be compacted by gravity. Hyperion may thus be compared to a gigantic mound of rubble. The moons of Saturn have been linked to Kronus' mythological brothers and sisters, according to John Herschel. (NASA)
