69230 Hermes - Wikipedia
网页69230 Hermes is a sub-kilometer sized asteroid and binary system on an eccentric orbit, [10] classified as a potentially hazardous asteroid and near-Earth object of the Apollo group, that passed Earth at approximately twice the distance of the Moon on 30 October 1937.
Asteroid Hermes | Space Reference
网页2019年5月8日 · Hermes is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Hermes as a "Potentially Hazardous Asteroid" due to its predicted close pass (es) with Earth. Hermes orbits the sun every 778 days (2.13 years), coming as close as 0.62 AU and reaching as far as 2.69 AU from the sun. Based on its brightness and the way it ...

Radar observations of long-lost asteroid 1937 UB (Hermes)
网页Asteroid 1937 UB (Hermes) is a large (~1 km) object of considerable historical and dynamical interest. It eluded astronomers for 66 years between its 1937 apparition and 2003 rediscovery. As of Oct 2003, it was the largest asteroid ever observed to make a close approach to Earth within less than twice the distance to the Moon.

网页2004年12月1日 · The Asteroid Hermes (1937 UB) was first detected in October 1937, when it made a very close pass to the Earth ( ∼ 2 lunar distances, or 800,000 km). Because the astrometric measurements during the discovery apparition covered only 5 days, the orbit could not be precisely determined and the object was soon lost.
