mp|(24835) 1995 SM|55, also written (24835) 1995 SM55, is a trans-Neptunian object (TNO) that resides in the Kuiper belt.

Discovered

It was discovered on September 19, 1995 by Nichole M. Danzl. Detected by a common pattern of IR water-ice absorption and a clustering of their orbital elements.

Origin

Based on their common pattern of IR water-ice absorption and a the clustering of their orbital elements, the KBOs mp|1995 SM|55, mpl|(19308) 1996 TO|66, 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.
