[edit] Origin

Main article: Haumea family

Based on their common pattern of IR water-ice absorption and a the clustering of their orbital elements, the KBOs (120178) 2003 OP32, 1995 SM55, (19308) 1996 TO66, (55636) 2002 TX300, and (145453) 2005 RR43 appear to be collisional fragments broken off the dwarf planet Haumea.
