Radar data of asteroid 2014 HQ124 taken over four hours on June 8, 2014, when the asteroid was between 864,000 miles (1.39 million kilometers) and 902,000 miles (1.45 million kilometers) from Earth. The data reveals asteroid 2014 HQ124 to be an elongated, irregular object that is at least 1,200 feet (370 meters) wide on its long axis. The radar data were obtained using NASA's 70-meter Goldstone antenna, the same antenna used for communicating with spacecraft in deep space. The Goldstone radar team paired with the Arecibo Observatory (Goldstone sending radar, Arecibo receiving) for the first five frames of this movie in order to collect higher quality data, resulting in sharper images. The other frames were made by both sending and receiving with antennas at the Goldstone complex.
