It has an estimated diameter of {{val|679|55|-73|u=km}}.[6] It was discovered by Andrew Becker, Andrew Puckett and Jeremy Kubica on 10 September 2005 at Apache Point Observatory in Sunspot, New Mexico. It is possibly a dwarf planet.[1][2] ClassificationThe Minor Planet Center (MPC) classifies it as a cubewano.[3] But since this object has an inclination of 19.3° and it is unknown how it acquired this moderate inclination,{{Citation needed|date=May 2012}} the Deep Ecliptic Survey (DES) classifies it as scattered-extended.[4] It has been observed 119 times over thirteen oppositions, with precovery images back to 1954.
