Saturn's Spongy Moon


The picture on the right is of Saturn's moon, Hyperion. This was taken during Cassini's close flyby on Sept. 26, 2005. Hyperion literally tumbles around chaotically in its orbit. It is tugged by the gravitational pull of both Saturn and Titan. Because of this, the moon changes both its rotational speed and its axis of rotation. Hyperion is composed of water ice mixed with dust.
The picture on the left is a sponge!
