What is special about Dione?

What is special about Dione?

Dione is the fourth-largest moon of Saturn, with a diameter of 698 miles (1,123 kilometers). It is the 15th largest moon in the solar system. Dione orbits around Saturn once every 2.7 Earth-days, at a distance of 234,000 miles (377,400 km), approximately the same distance from Earth to its moon.

Does Dione moon have water?

Deep inside Saturn’s moon Dione lies a global ocean of liquid water, according to scientists of the Royal Observatory of Belgium. Such discovery places Dione as the third Saturn’s moon, beside Enceladus and Titan, to have a subsurface ocean.

Can we live on Dione moon?

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.

What is the gravity on Rhea?

What is Dione the god of?

The Greek goddess of love sometimes takes the name Dione: this may identify her with Aphrodite, though Homer calls Dione the mother of Aphrodite.

Is there oxygen on Dione?

Dione, one of Saturn’s icy moons, has a weak exosphere which includes molecules of oxygen, according to new findings from the Cassini-Huygens mission.

Is Dione 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.

How long is a day on Dione?

How long is a day on Dione? Edit. It takes 2.74 days to complete an orbit around Saturn. This is just under 2 days and 18 hours.

What is Dione made of?

Dione’s density is 1.48 times that of liquid water, suggesting that about a third of Dione is made up of a dense core (probably silicate rock) with the remainder of its material being ice.

Which moon has the most oxygen?

Astronomers using the Hubble telescope have identified the presence of an extremely tenuous atmosphere of molecular oxygen around Jupiter’s moon, Europa.

Can habitable moons exist?

Most notably, it was found that moons at distances between about 5 and 20 planetary radii from a giant planet could be habitable from an illumination and tidal heating point of view, but still the planetary magnetosphere would critically influence their habitability.

Would Jupiter’s moons support life?

NASA reports that the ice-covered oceans of Europa – a moon of Jupiter which is currently the closest it has been to Earth in 59 years – could host alien life. NASA believes that its “rock-hard” icy crust covers a “huge, salty, liquid ocean” beneath.

Is there any gravity on Titan?

Titan’s dense atmosphere, as well as gravity roughly equivalent to Earth’s Moon, mean that a raindrop falling through Titan’s sky would fall more slowly than on Earth.

Did the Death Star have gravity?

The Death Star’s gravity is so small that if it were to orbit the Earth where the Moon is, we’d hardly notice any difference. The Moon is 40,000 times more massive than the Death Star!

Is there oxygen on Rhea?

Oxygen at Rhea’s surface is estimated to be about 5 trillion times less dense than what we have at Earth. But the new results show that surface decomposition could contribute abundant molecules of oxygen, leading to surface densities roughly 100 times greater than the exospheres of either Earth’s moon or Mercury.

What is Dione in Greek mythology?

Dione, in Greek mythology, a consort and, at Dodona in Epirus, a cult partner of Zeus, the king of the gods. Since the partner and wife of Zeus was normally the goddess Hera, it has been conjectured that Dione is an older figure than Hera. Dione was variously described.

Who is known for being the most beautiful goddess?

Aphrodite was the most beautiful of all the Goddesses. Aphrodite was the most beautiful of all the Goddesses and there are many tales of how she could encourage both Gods and humans to fall in love with her.

What is Dione made of?

Dione’s density is 1.48 times that of liquid water, suggesting that about a third of Dione is made up of a dense core (probably silicate rock) with the remainder of its material being ice.
