New views of an NEO (near Earth object).
According to the article, "The radar measurements further refined the asteroid's trajectory, allowing computer models to accurately compute 2007 PA8's orbit for the next 632 years. NASA scientists were also able to confirm that this was the closest flyby since 1880 and the next flyby that brings the asteroid closer to Earth won't be until 2488".
These images were obtained by radar.
