It was discovered by American astronomers Eleanor Helin and Jeff Alu at the Palomar Observatory in California on 24 September 1992.
This makes the body a potentially hazardous asteroid, because its MOID is less than 0.05 AU and its diameter is greater than 150 meters.
[1] The first precovery was obtained at Palomar Observatory in 1953, extending the asteroid's observation arc by 39 years prior to its discovery.
In 1999, Czech astronomer Petr Pravec constructed a lightcurve, that rendered a rotation period of 7.328 hours and a brightness variation of 0.72 in magnitude (U=n/a).
[a] In March 2006, observations by astronomer David Polishook from the ground-based Wise Observatory, Israel, gave a rotation period of 7.31 and amplitude of 0.70 mag (U=2),[8] and in November 2011, American astronomer Brian Warner at the Palmer Divide Observatory, Colorado, obtained the first well-defined period of 7.323 hours with an amplitude of 0.50 mag (U=3).
