Can Dione support life?
(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.
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.
What is the temperature on Dione?
-304 degrees Fahrenheit
At Dione’s average temperature of -304 degrees Fahrenheit (-186 degrees Celsius or 87 kelvins), ice is very hard and behaves like rock.
Who is the God Dione?
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.

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.
When was Dione discovered by the Cassini spacecraft?
Saturn’s moon Dione is captured in this view from NASA’s Cassini spacecraft, half in shadow and half in light. Image Credit: NASA/JPL-Caltech/Space Science Institute Giovanni Cassini discovered Dione on March 21, 1684.
How did Dione spin around in the Solar System?
Surface. Logically, a moon’s leading hemisphere should be the more heavily cratered, so it has been theorized that a more recent impact spun Dione around. It has been calculated that bodies as small as those that made 22-mile (35-km) craters on Dione could have spun the moon around to its current position.
How is Dione related to the other moons of Saturn?
Just like Earth’s Moon, Dione is phase locked with its parent; one side always faces toward Saturn. Likewise, Dione has gravitationally locked two much smaller moons: Helene orbits Saturn 60 degrees ahead of Dione, and Polydeuces orbits Saturn 60 degrees behind Dione.
Why is Dione in resonance with Mimas and Enceladus?
Dione is in resonance with two nearby moons, Mimas and Enceladus. That is, these moons speed up slightly as they approach each other and slow down as they draw away, causing their orbits to vary slightly in a long series of complex changes, which helps keep them locked in their positions.
