Discovered on 21 June 1990 by H. E. Holt at Palomar.
Peter Erwin (1966–2025) was an American astronomer who studied galactic single and double bars, composite bulges and outer disc profiles. After his Ph.D. at the University of Wisconsin, he moved to Tenerife, then to the Max-Planck-Institut für extraterrestrische Physik. Peter developed a widely-used galaxy-fitting software program.Naming citation (WGSBN Bull. 6, #2, 7), IAU / Minor Planet Center, via NASA/JPL
