UGC 12682 is an irregular galaxy, located in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 1024 ± 25 km/s, which corresponds to a Hubble distance of 49.2 ± 3.7 Mly (15.10 ± 1.12 Mpc).[3] In addition, one non redshift measurement gives a distance of 65 Mly (20.0 Mpc).[4] The earliest known reference to this galaxy is from the 1959 journal A Catalogue of Dwarf Galaxies by Sidney Van Den Bergh, where it is listed as DDO 218.[5]
On 7 November 2008, 14-year-old amateur astronomer Caroline Moore from Warwick, New York, became the youngest supernova discoverer at the time, when she found SN 2008ha (type Ia, mag. 18.8)[6] in UGC 12682.[1][7]
