There are precovery images dating back to 10 February 1996. The orbit is well determined with an observation arc of 14.9 years which includes two radar delay observations. It has an Uncertainty Parameter of 0. The asteroid will pass 248700 km LD on off from the Earth on 26 June 2028. During the close approach, the asteroid should peak at about apparent magnitude 6.7, and will be visible in binoculars. It has an absolute magnitude (H) of 18.2. According to observations by the NEOWISE mission, the asteroid measures approximately 0.9 km in diameter and its surface has a rather low albedo of 0.097. left References 30em 2017-12-26 last obs.
