Hermes, a large asteroid that skimmed by the Earth in 1937 but has never been seen again, has been spotted once more after years of effort by astronomers, the International Astronomical Union (IAU) said.
”A bright near-Earth candidate” reported by astronomer BA Skiff early on Wednesday, was confirmed within four hours as Hermes by a visual sighting by another astronomer, the Paris-headquartered IAU’s Minor Planet Centre said in a circular received in Paris on Thursday.
Further calculations are being done to determine its orbit, although early estimates suggest that the rock, formally called 1937 UB (Hermes), takes a little more than two years to go around the Sun, the circular said.
Hermes created a stir when it flew by close to the Earth in October 1937 at a distance of less than a million kilometers, just 60% further than the distance of the Earth to the Moon.
Estimated at the time to be about 800m across, Hermes swiftly disappeared from view, leaving doubts about whether its orbit would again bring it so close, or even closer, to the Earth.
Asteroids are speculated to be the rubble left over from the making of the solar system — space rocks that orbit the Sun, although sometimes at long and highly elliptical orbits. — Sapa-AFP
