(19308) 1996 TO66 (also written (19308) 1996 TO66) is a trans-Neptunian object. It was discovered in 1996 by Chadwick A. Trujillo, David C. Jewitt and Jane X. Luu.
Origin
Main article: Haumea family
Based on their common pattern of IR water-ice absorptions and neutral visible spectrum,[7] and the clustering of their orbital elements, the KBOs (19308) 1996 TO66, (24835) 1995 SM55, (55636) 2002 TX300, (120178) 2003 OP32, and (145453) 2005 RR43 appear to be collisional fragments broken off the dwarf planet Haumea.
