Initial Radar 'Images' of Asteroid 2012 DA14
Date: 16 Feb 2013
This collage of 72 individual radar-generated images of asteroid 2012 DA14 was created using data from NASA's 230-foot (70-m) Deep Space Network antenna at Goldstone, Calif. The data were collected on the night of 15 to 16 Feb. 2013, after the asteroid had made its closest approach to Earth and was exiting the Earth-moon system. During the observations, the space rock's distance to Earth increased from 74,000 to 195,000 miles (120,000 to 314,000 km).
