Good to know the Spaceguard
teams are keeping an eye out for us. The eagle-eyed observers at the Catalina Sky Survey have spotted an asteroid
which will pass relatively close to Earth
this Thursday, April 8, 2010 at 23:06 U.T.C. (4:06 p.m. PDT, 7:06 pm EDT). But it should pose no problem, as at the time of closest approach asteroid
2010 GA6 will be about 359,000 kilometers (223,000 miles) away from Earth – about 9/10ths the distance from to the moon
. The asteroid is approximately 22 meters (71 feet) wide.
"Fly bys of near-Earth objects within the moon
occur every few weeks," said Don Yeomans of NASA's Near-Earth Object Office at the Jet Propulsion
Laboratory in Pasadena, Calif.
This one, however, is a bit bigger than other recent asteroid alerts NASA's Near Earth Observation program has issued. In November 2009, a 7-meter asteroid called 2009 VA
came within 14,000 km (8,700 miles) of Earth and in January, 2010 AL30 was about 10-15 meters
long and came within only 128,000 km (about 80,000 miles).
NASA's NEO program, also called Spaceguard, discovers these objects, characterizes a subset of them and plots their orbits
to determine if any could be potentially hazardous to our planet
So while you're waiting for this one to pass by you can read Don Yeoman's top ten favorite asteroid facts.
The Catalina telescope
is in Tucson, Arizona.
