A Little Pas de Deux: Tethys and Dione

Saturn's moons Tethys and Dione pass each other from Cassini's point of view. (CLICK TO PLAY)

Saturn’s moon Tethys, its giant Odysseus crater in plain view, passes in front of of the slightly darker Dione in this animation made from several raw images acquired by Cassini earlier this month. Pretty cool!

Tethys and Dione are similar in diameter, being 1,062 kilometers (660 miles) wide and 1,123 kilometers (698 miles) wide, respectively. Both are heavily cratered icy worlds.

A slight rotation in Tethys can also be discerned.

    As awesome as this is, it’s equally awesome that we can sit at our desks and watch it. It’s not so long ago, relatively speaking, that this would not be possible.

    Woohoo!!
