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.
