UGC 12682 explained

UGC 12682 is an irregular galaxy, located in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 1024 ± 25km/s, which corresponds to a Hubble distance of NaNMpc. In addition, one non redshift measurement gives a distance of 20abbr=onNaNabbr=on.^[3] 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.^[4]

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 (typeIa, mag. 18.8)^[5] in UGC 12682.^[6]
