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.

1K views · 117 reactions | Nasa's hubble space telescope has located what scientists believe is the largest comet ever seen by astronomers. They estimate the diameter to be about 80 miles across--making it larger than the state of rhode island. Judging by its nucleus, it is about 50 times larger than an average comet and weighs 100,000 times more. Don't fret, astronomers say the giant icy rock poses no risk to earth. | Allison Miller | Facebook
