What is unique about Dione?
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.
How big is the Dione moon?
561.4 km
Dione/Radius
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. This suggests the moon’s interior is very similar to its smaller but more famous neighbor Enceladus.
What is Dione made out 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.
Does Saturn have 62 or 82 moons?
Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming. Saturn’s moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena.
What is Dione The God of?
Dione (/daɪˈoʊniː/; Ancient Greek: Διώνη, romanized: Diṓnē, lit. 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.
Can the moon Dione support life?
This small, icy moon has a global subsurface ocean that could possibly support life. Image via NASA/JPL-Caltech/NASA Science. Using data from the Cassini mission, which ended in late 2017, they created 50 different simulations of conditions in Enceladus’ ocean.
Does Dione Moon have water?
Saturn’s icy moon Dione may have a subsurface liquid water ocean. They reconstructed Dione’s gravity field, combined it with measurements of topography, and then matched the geophysical properties with models of the interior structure.
Who discovered Dione moon?
Giovanni Domenico Cassini
Dione/Discoverers
Giovanni Domenico Cassini named the four moons he discovered (Tethys, Dione, Rhea and Iapetus) Sidera Lodoicea (“the stars of Louis”) to honor king Louis XIV. Cassini found Dione in 1684 using a large aerial telescope he set up on the grounds of the Paris Observatory.
Does Saturn have 82 moons?
Saturn has 82 moons. Saturn’s moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena. The moons shape, contribute and also collect material from Saturn’s rings and magnetosphere.
What are 5 facts about Saturn?
Here are some fun facts about the Ringed Planet.
- Saturn is huge.
- You cannot stand on Saturn.
- Its beautiful rings are not solid.
- Some of these bits are as small as grains of sand.
- The rings are huge but thin.
- Other planets have rings.
- Saturn could float in water because it is mostly made of gas.
Who is the mother of Hermes?
Maia
Hermes/Mother
There Mercury was associated with Maia, who became identified as his mother through her association with the Greek Maia, one of the Pleiades, who was the mother of Hermes by Zeus; likewise, because of that Greek connection, Mercury was considered the son of Jupiter. Both Mercury and Maia were honoured…
Why are the moons of Saturn called Dione?
Other astronomers called the Saturn moons by number in terms of their distance from Saturn. Thus, Dione was Saturn IV. John Herschel suggested that the moons of Saturn be associated with the Greek mythical brothers and sisters of Kronus. (Kronus is the equivalent of the Roman god Saturn in Greek mythology.)
Which is the fourth largest moon of Saturn?
Dione is the fourth largest moon of Saturn. It has a diameter of 1,123 km (698 miles). It was discovered in 1684 by Giovanni Domenico Cassini. It is named after the titan Dione in Greek mythology. The moon has many craters and ice cliffs. It is tidally locked with Saturn, meaning the same face of Dione always faces Saturn.
How big is Dione compared to the Earth?
Dione has an estimated radius of 348.8 miles (561.4km). This makes Dione about one third of the size of the Earth’s moon, and around 20% of the largest moon in our solar system, Ganymede. Dione orbits Saturn at a distance of 234,500 miles (377,400 km).
How long does it take Dione to orbit Saturn?
Dione orbits Saturn at a distance of 234,500 miles (377,400 km). To complete one full trip around Saturn, it only takes Dione around 2.7 days. Dione takes it’s named from a Titaness from Greek mythology. It was discovered back in 1684 by astronomer Giovanni Cassini, more than 70 years after Saturn was first seen by Galileo.
