Hubble determined the size of the largest icy comet nucleus ever seen! At 80 miles across and 50 times larger than typical comets, this comet is larger than the state of Rhode Island. It's barreling in our direction at 22,000 miles per hour, but don't worry – it won't get closer than roughly a billion miles from the Sun, slightly farther out than Saturn.
