Article
2135 Aristaeus (1977 HA) is an Apollo asteroid discovered on 17 April 1977, by E. F. Helin and S. J. Bus at Palomar Observatory. It is named for Aristaeus, the son of Apollo and the nymph Cyrene.
2135 Aristaeus is a potentially hazardous asteroid (PHA) because its minimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is greater than 150 meters. The Earth-MOID is 0.0100 AU (1,500,000 km; 930,000 mi). Its orbit is well-determined for the next several hundred years.
