Behind The Black Postings By Robert Zimmerman

Impressive radar images of near-Earth asteroid 2007 PA8 were taken during its recent fly-by of Earth.

The images … reveal possible craters, boulders, an irregular, asymmetric shape, and very slow rotation. The asteroid measures approximately one mile wide (about 1.6 kilometers).

The asteroid poses no threat to Earth. The resolution of the images, however, is astonishing, especially considering it was done by radar.

  1. Good point, Bob. The images are so good, they look like optical photographs.
