Asteroid Due for Close Approach

mernil writes "BBC Reports "A giant space rock was set to whizz past the Earth on Monday under the close scrutiny of astronomers. The mountain-sized object had been classed as a "potentially hazardous asteroid", but scientists say there was no danger of a collision with Earth. [...] At this time calculations suggested it would be about 268,873 miles (432,709km) from the Earth, only 1.1 times the planet's distance from the Moon."
