What planet does the moon Dione orbit?
Saturn
Dione is a small moon of 349 miles (562 km) in mean radius orbiting Saturn every 2.7 days at a distance of 234,500 miles (377,400 km), which is roughly the same distance that the moon orbits around the Earth.
What is Dione moon made of?
Dione is the densest of Saturn’s moons with the exception of Titan. It is composed mainly of water ice, but must contain a larger amount of rocky material than Saturn’s other ice moons, Tethys and Rhea. Dione is very similar to Rhea in composition, although somewhat smaller and much denser.
Is Dione moon habitable?
If Dione has an existing ocean, it would probably have survived for the whole history of the moon, and thus could offer a long-lived habitable zone for microbial life, according to the study’s authors. According to the model, Dione’s ocean would be several tens of kilometers deep and would surround a large rocky core.
How was Dione formed?
Created by tectonic activity, these fractured areas crisscross the moon, running tens to hundreds of kilometers in length. Cassini also detected a wispy oxygen atmosphere on Dione. It is very thin; there is just one oxygen ion for every 0.67 cubic inches (11 cubic centimeters).
How far away is Dione from Saturn?

Who is the God Dione?
DIONE was the Titan goddess of the oracle of Dodona in Thesprotia, and the mother of Aphrodite by Zeus. Her name is simply the feminine form of Zeus (Dios).
Can we live on Dione?
A NASA spacecraft circling Saturn has discovered a wispy oxygen atmosphere on the ringed planet’s icy moon Dione, but you wouldn’t want to live there. For one thing, you wouldn’t be able to breathe — Dione’s atmosphere is 5 trillion times less dense than the air at Earth’s surface, scientists say.
Is there life on Dione?
(Related: “Saturn Moon Has Ice Volcano—And Maybe Life?”) Dione itself isn’t a candidate for extraterrestrial life. With an average temperature of -121 Fahrenheit (-186 Celsius), the moon isn’t known to have any liquid water, a prerequisite for life as we know it.
Does Dione have an ocean?
The icy Saturn moon Dione appears to have an underground ocean of liquid water, just like two of its more famous neighbors, a new study suggests. This huge ocean is probably buried about 60 miles (100 kilometers) beneath Dione’s icy shell, according to the study.
What is Dione Roman name?
Dione is translated as “Goddess”, and given the same etymological derivation as the names Zeus, Diana, et al. One Dione is identified as the mother of the Roman goddess of love, Venus, or equivalently as the mother of the Greek goddess of love, Aphrodite; but Dione is also sometimes identified with Aphrodite.

What planet is Titan from?
Titan is the sixth gravitationally rounded moon from Saturn. Frequently described as a planet-like moon, Titan is 50% larger than Earth’s moon and 80% more massive.
Is Rhea a moon?
Rhea (moon) Rhea ( /ˈriːə/ REE-ə; Ancient Greek: Ῥέᾱ) is the second-largest moon of Saturn and the ninth-largest moon in the Solar System. It is the second smallest body in the Solar System—after the asteroid and dwarf planet Ceres —for which precise measurements have confirmed a shape consistent with hydrostatic equilibrium.
