Radar-imaging of 2006 DP14

2006 DP14 is a Near-Earth object that passed within about 11 lunar distances of Earth in early February 2014.[1] On the night of February 11, 2014 NASA scientists conducted a radar imaging session using the Goldstone 70 m (230 feet) dish.[1] These observations revealed its basic shape and size; it appears to be about 400 × 200 m.[1] Amateur and professional astronomers helped track the asteroid in the preceding days, so they would know just where to point the large antenna.[1]
