PGC 44691 is a spiral galaxy located about 350 million light-years away[2] in the constellation Coma Berenices.[3] It belongs to a galaxy cluster known as the Coma Cluster.[4][5] In 1994, the Hubble Space Telescope observed PGC 44691 and the nearby elliptical galaxy NGC 4881 to infer the distance to the Coma Cluster.[4]
