Classification

The Minor Planet Center (MPC) classifies it as a cubewano. But since this object has an inclination of 19.3° and it is unknown how it acquired this moderate inclination, the Deep Ecliptic Survey (DES) classifies it as scattered-extended.

It has been observed 119 times over thirteen oppositions, with precovery images back to 1954.
