mp|(120178) 2003 OP|32, also written as (120178) 2003 OP32,is a trans-Neptunian object (TNO) that resides in the Kuiper belt. It was discovered on July 26, 2003 by Michael E. Brown, Chad Trujillo, and David L. Rabinowitz.

Origin

Based on their common pattern of IR water-ice absorption and a the clustering of their orbital elements, the KBOs mpl|(120178) 2003 OP|32, mp|1995 SM|55, mpl|(19308) 1996 TO|66, mpl|(55636) 2002 TX|300, and mpl|(145453) 2005 RR|43 appear to be collisional fragments broken off the dwarf planet dp|Haumea.
