Year-old discovered asteroid to return Feb15

Asteroid 2012 DA14, which was discovered a year ago when it came closest to the Earth , will come closer to the planet again on the night of February 15. The asteroid, about 148 ft in diameter and weighing 1.30-lakh tonne, will be as close as 34,100 km from the centre of the earth the point of closest approach. But it will come closer than some of the geostationary satellites orbiting the earth, said M P Birla planetarium director D P Duari on Wednesday. Given the radius of the Earth, it will be about 28,000 km from the earth's surface, a small distance in terms of astronomical figures, he said.
