This 73-frame movie of asteroid 2012 DA14 was generated from data obtained by NASA's Goldstone Solar System Radar on the night of February 15 to 16, 2013.
This collage of 72 individual radar-generated images of asteroid 2012 DA14 was created using data from NASA's 230-foot (70-meter) Deep Space Network antenna at Goldstone, California. The data were collected on the night of February 15 to 16, 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 kilometers).
