POTENTIALLY HAZARDOUS ASTEROID THAT ZIPPED PAST EARTH HAS ITS OWN 'MOON' "Potentially hazardous" NEOs (Near Earth Objects) are defined as space objects that come within 0.05 astronomical units and measure more than 460 feet in diameter, according to NASA. One of the study's co-authors, astrono...
A "potentially hazardous asteroid" that whizzed past Earth earlier this month is so large it has its own "moon."
