New images of Saturn's moon Dione were taken
and released today.
The pockmarked moon is seen by NASA's Cassini
spacecraft as a partial globe hanging in space, as well as in close-ups that
reveal its many craters.
Dione is an icy ball. It has a radius of 348 miles
(560 kilometers) and orbits Saturn every 2.73 days from 234,505 miles (377,400
kilometers) away.
Dione's average surface temperature is minus 303
Fahrenheit (-186 Celsius). It is covered by smooth plains and not too many
craters — all a sign of cryovolcanism, or an outpouring of icy
liquid from the interior.
