On this day in 1671, astronomer Giovanni Cassini first observed Saturn’s moon Lapetus. Lapetus is a strange beast, with one light hemisphere and one dark hemisphere, and a huge equatorial ridge of some of the Solar System’s tallest mountains.

Isn't it usually spelled Iapetus or Japetus (as in 2001 a Space Odyssey)?
