It was discovered on 22 June 1993, by American astronomers Eleanor Helin and Kenneth Lawrence at the U.S. Palomar Observatory in California.
As it crosses the orbit of Mars, it may also be classified as a Mars-crosser, and, on 28 November 2023, it will pass 0.02535 AU (3,792,000 km) from the Red Planet.
[1] The first precovery was taken at the Australian Siding Spring Observatory in 1981, extending the body's observation arc by 12 years prior to its discovery.
In the 1990s, Italian astronomer Stefano Mottola obtained a lightcurve at La Silla during the EUNEASO, a European near-Earth object search and follow-up observation program to determine additional physical parameters (U=3).
[5][b] In June 2016, the fourth and most recent photometric observation was made by American astronomer Brian Warner at his Palmer Divide Station, Colorado, which gave a period of 4.948±0.005 hours with an amplitude of 0.82 in magnitude (U=3).
