Origin
Based on their common pattern of infrared water-ice absorption and the clustering of their orbital elements, the other KBOs 1995 SM55, (19308) 1996 TO66, (55636) 2002 TX300 and (145453) 2005 RR43, among others, appear to be collisional fragments broken off the dwarf planet Haumea. The neutral color of the spectrum of these objects in the visible range evidences a lack of complex organics on the surface of these bodies that has been studied in detail for the surface of Haumea.
