(24835) 1995 SM55, also written (24835) 1995 SM55, is a trans-Neptunian object (TNO) that resides in the Kuiper belt that was discovered on September 19, 1995, by Nichole M. Danzl.
Origin
Main article: Haumea family
Based on their common pattern of IR water-ice absorptions, neutral visible spectrum[10] and the clustering of their orbital elements, the other KBOs (19308) 1996 TO66, (55636) 2002 TX300, (120178) 2003 OP32 and (145453) 2005 RR43 all appear to be collisional fragments broken off of the dwarf planet Haumea.
