(214869) 2007 PA8 is an asteroid roughly 1.6 km in diameter and that came within 6.5 million km (4 million miles, 17 lunar distances) to Earth on November 5, 2012.[1][2] It was discovered on August 9, 2007 by LINEAR.[2] It was studied by the Goldstone radar as it came near Earth, which resulted in images and other data about the asteroid, such as its rotation rate.[2] It has an Apollo type orbit and is classified as a potentially hazardous asteroid (PHA).[2]
2007 PA8 may be a dormant comet related to the November γ Pegasids meteor shower.[3]
