[edit] Origin
Main article: Haumea family
Based on their common pattern of IR water-ice absorptions and neutral visible spectrum,[10] and the clustering of their orbital elements, the KBOs 1995 SM55, (19308) 1996 TO66, (55636) 2002 TX300, (120178) 2003 OP32, and (145453) 2005 RR43 appear to be collisional fragments broken off the dwarf planet Haumea.
