Record-Breaking Asteroid to Pass Earth Tonight (15th)

By John Pustelnik

An asteroid will pass by Earth tonight, the largest asteroid recorded to ever pass Earth at such a close range.

It will be closest to the Earth at 19:25 GMT. At this time, the asteroid will be about 17,200 miles (27,000km) from Earth.


The asteroid is about 150ft (45m) in diameter.

It will pass the Earth at 17,450mph (28,080kph).

It is best viewable in Australia, Asia, and Eastern Europe. It may be difficult to see with the naked eye, but should be visible with a pair of binoculars.

The asteroid can also be viewed online. NASA is streaming the event on Ustream. (link below)

The asteroid was first discovered in February of 2012.

"When asteroids come this close, it`s very important to try to learn about them, it`s become so bright, so it`s so easy to study," said Alan Fitzsimmons of Queens University Belfast.
