An asteroid the size of a bus came to within 186,000 miles of Earth
– a close shave in cosmic terms – on Saturday morning. The
recently-detected asteroid HL129 was closer to Earth than the Moon –
which is on average 238,855 miles away from our planet – on its closest
approach at 4.13am.
The asteroid is
about 7.6 metres wide, according to NASA’s Asteroid Watch project based
at the agency’s Jet Propulsion Laboratory in Pasadena, California
An asteroid of
that size would cause significant damage if it impacted a major city,
potentially hitting with the impact of a nuclear bomb roughly half the
size of the one that hit Hiroshima in 1945.
The asteroid was
discovered on Wednesday, April 28, by astronomers with the Mount Lemmon
Survey team, according to an alert by the Minor Planet Center, an arm of
the International Astronomical Union that chronicles asteroid
discoveries, reports.
