Iapetus, the next to outermost, is 900 miles in diameter. It is over 2,200,000 miles distant from Saturn. Once again, Iapetus is thickly and uniformly sprinkled with thousands of craters. Satellites of Uranus Uranus has five small satellites, named Miranda, Ariel, Umbriel, Titania and Oberon. Some very violent physical geography is found among these satellites, astounding astronomers.
Interpretations are yet to be established.
As all realize, the Moon is badly pocked on both sides with craters. Craters on Mercury are even denser and bigger. A dozen satellites of Jupiter, Saturn and Uranus are known to be badly battered and heavily sprinkled with craters. We find evidence indicating that all of these planets and their satellite systems formerly were in deep space, beyond 900 a.u. There must be blizzards of bad luck battering blast-creating ballistics in the region from where these planets and their satellites have come.
