trans-Neptunian object (TNO) that resides in theKuiper belt . It was discovered onJuly 26 ,2003 byMichael E. Brown ,Chad Trujillo , andDavid L. Rabinowitz .Origin
Based on their common pattern of IR water-ice absorption and a the clustering of their orbital elements, the KBOs mpl|(120178) 2003 OP|32, mp|1995 SM|55, mpl|(19308) 1996 TO|66, mpl|(55636) 2002 TX|300, and mpl|(145453) 2005 RR|43 appear to be collisional fragments broken off the
