mp|(19308) 1996 TO|66 (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

Based on their common pattern of IR water-ice absorption and a the clustering of their orbital elements, the KBOs mpl|(19308) 1996 TO|66, mpl|(24835) 1995 SM|55, mpl|(55636) 2002 TX|300, mpl|(120178) 2003 OP|32, and mpl|(145453) 2005 RR|43 appear to be collisional fragments broken off the dwarf planet dp|Haumea.
