(24835) 1995 SM55, 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

1995 SM55 and four other objects ((19308) 1996 TO66, (55636) 2002 TX300, (120178) 2003 OP32, and (145453) 2005 RR43) appear to be fragments sheared off parent body (136108) 2003 EL61 by a collision.
