(214869) 2007 PA8 is an asteroid and slow rotator, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometers in diameter.

It came within 6.5 million km (4 million miles, 17 lunar distances) of Earth on 5 November 2012.[8][9]

It was discovered on 9 August 2007, by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Lincoln Laboratory Experimental Test Site in Socorro, New Mexico.[2]

It was studied by the 70-meter (230 ft) Goldstone Deep Space Network antenna as it came near Earth, which resulted in radar images and other data about the asteroid, such as its very long rotation period of approximately 100 hours.[9]

2007 PA8 may be a dormant comet related to the November γ Pegasids meteor shower.[10]
