Comet Dust over Enchanted Rock
14.08.2015

Dusty debris from periodic Comet Swift-Tuttle was swept up by planet Earth this week.

First, Janus travels in an unusual orbit around Saturn where it periodically trades places with its sister moon Epimetheus, which typically orbits about 50 kilometers away. Janus, although slightly larger than Epimetheus, is potato-shaped and has a largest diameter of about 190 kilometers.
