Radar Images Asteroid 2007 PA8

Scientists working with NASA's 70-metre Deep Space Network antenna at Goldstone, Calif., have obtained several radar images depicting near-Earth asteroid 2007 PA8. The images were generated from data collected at Goldstone on Oct. 28, 29 and 30, 2012. The asteroid's distance from Earth on Oct. 28 was 10 million kilometres. The asteroid's distance to Earth was 9 million kilometres on Oct. 30. The perspective in the images is analogous to seeing the asteroid from above its north pole. Each of the three images is shown at the same scale.
