This would have meant the newly formed moon was covered entirely in magma: a global magma ocean, so hot and deep that it took at least tens of millions of years to cool and solidify into rock.

The ocean is believed to fill half of Mimas’ volume, according to Lainey. Yet it represents only 1.2 percent to 1.4 percent of Earth’s oceans given the moon’s petite size.
