It was discovered by Eleanor F. Helin at the Palomar Observatory in San Diego County, California, on June 26, 1990. This object is approximately {{convert|0.7|km|mi}} in diameter, and listed as a potentially hazardous object.[2] On July 23, 2020, it will come within 0.055 au of the Earth—about 21.3 times the Moon's distance.[3] See also
