Three precovery images are known from 1 July 1995. With an observation arc of 16 years, the orbit is well determined with an orbital uncertainty of 0. With an absolute magnitude of 20.0, the asteroid is about 270–590 meters in diameter.

With a Mars-minimum orbit intersection distance of 0.002 AU, the asteroid currently makes closer approaches to Mars than it does Earth. On 29 July 2014 the asteroid passed 0.00805 AU from Mars.
