London: n asteroid
larger than an aircraft carrier will dart between the Earth and
Moon Tuesday. It will be the closest encounter by such a huge
space rock in 35 years.
The asteroid, named 2005 YU55, is a quarter-mile across and is
being watched by ground antennas in California and Puerto Rico as
it approaches from the direction of the Sun, the Daily Express
The closest point will occur at 11.28 p.m. Tuesday when the
asteroid passes within 202,000 miles of Earth and 150,000 miles
from the Moon.
Unlike any fictional asteroid, scientists say, this will not
threaten to destroy Earth.
"We're 100 percent confident that this is not a threat," said Don
Yeomans, the manager of NASA's Near Earth Object Programme.
According to Jay Melosh, professor of Earth and atmospheric
sciences at Purdue University in Indiana, both -- the Earth and
Moon -- are safe "this time".
If 2005 YU55 was to hit earth, it would blast out a crater four
miles across and 1,700ft deep, said Melosh.
