Asteroids near Jupiter are really comets was created by Seanie_Morris

Two objects lurking near Jupiter and once considered rocky asteroids have turned out to be comets made up mostly of ice and dirt.

Using the Keck II Laser Telescope in Hawaii, astronomers found that the two objects, 617 Patroclus and its companion, Menoetius, had a density of only 0.8 grams per cubic centimeters -- only a third that of rock.
