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.
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.
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.

Saturn's icy moon Dione has an atmosphere, albeit a thin one, astronomers have discovered. NASA's Cassini spacecraft revealed Dione's atmosphere during a recent close flyby of the Saturnian satellite.
The Moon travels around the Earth in a circle called an orbit. It takes about 28 days to go one time around the Earth. The Sun always lights up half of the Moon at one time. The Moon is not a light source; it has no light of its own. We can only see the Moon because it reflects light from the Sun. The Moon appears to change shape (phases) but what we are actually seeking is the Moon lit up by.
The moon is the most noticeable feature in the night sky and it is also the brightest, but it doesn't give off its own light. It is, actually, reflecting the light given off by the sun. Only seven percent of the light from the sun is reflected. Sometimes, the moon appears to change shape, but it is only because the sun is lighting different parts of it. When the moon passes through the earth's.

Icy moon Dione has long, thin, bright lines at its equator that run surprisingly parallel to each other for tens to hundreds of kilometers.
Researchers have found hints of evidence suggesting that Saturn ’s moon Dione was likely active in the past, and could still be active now. From a distance, most of the Saturnian moon Dione resembles a bland cueball. Thanks to close-up images of a 500-mile-long (800-kilometer-long) mountain on the moon from NASA ’s Cassini spacecraft, scientists have found more evidence for the idea that.
Why is the Moon Important? Many people may not be aware of why the moon is important to us here on Earth. The evidence from the fossil record clearly shows that all life began in the oceans. At some stage, plants and creatures adapted to live on land. From the earliest land life, every living thing on land, from humans to animals, to plants, to.
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.
A new model of Saturn's moon, Dione, suggests it plays host to an ocean 100km below its surface. At least on Earth, where there's water, there is life. It's discovery on extraterrestrial bodies.
