Dione (moon) - Simple English Wikipedia, the free encyclopedia.

At 1 122 km (697 mi) in diameter, Dione is the 15th largest moon in the Solar System, and is more massive than all known moons smaller than itself combined. About two thirds of Dione's mass is water ice, and the remaining is a dense core, probably silicate rock. Data gathered by Cassini indicates that Dione has an internal liquid salt water ocean (a situation similar to that of its orbital.

Essay On Dione Moon

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. 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.

Saturn's Moon Dione - Universe Today.

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. References.Dione's surface consists of heavily cratered areas, moderate and lightly cratered plains, and bright, wispy features. Most of the heavily cratered areas exist on the trailing hemisphere of the moon. Some of these craters exceed 62 miles (100 km) in diameter, while most of the craters in the plains areas are less than 18 miles (30 km) in diameter. The largest crater is called Amata and is 150.The Saturn Moon Mimas Mimas is an inner moon of Saturn and is the innermost of the major moons, which are Enceliadus, Tethys, Dione, Rhea, Titan, Hyperion, Iapetus, and Phoebe. Mimas has a crater named the Herschel Crater, which is approximately 88 miles and one-third the diameter of Mimas. The walls of the Herschel Crater are approximately 3 miles high and parts of the floor of the crater.


Titan is a very planet like moon; its diameter is about 50% larger than Earth's moon and is nearly 80% more massive. It is the second largest moon in the Solar System, the largest is Jupiters moon Ganymede, and it is larger by volume than Mercury. Titan was the first known moon of Saturn. It was discovered in 1655 by the Dutch astronomer Christiaan Huygens. Titan is mostly composed of ice and.Dione is composed primarily of water ice, but as the densest of Saturn's moons (aside from Titan, whose density is increased by gravitational compression) it must have a considerable fraction of denser material like silicate rock in its interior. Though somewhat smaller, Dione is otherwise very similar to Rhea.They both have similar compositions, albedo features and varied terrain, and both.

Essay On Dione Moon

The generally accepted premise is that Dione was initially tidally locked in the opposite orientation during the period of heavy bombardment, which finished about 3.8 billion years ago. Its low mass means that an impact causing a crater about 35 km (21 miles) in diameter would be enough to spin the moon around. Dione has a great many craters this size and larger, so could have had changes in.
