Re: The Closest Near Miss On Record - Today

A small near-Earth asteroid (NEA), discovered Monday night by the NASA-funded LINEAR asteroid survey, will make the closest approach to Earth ever recorded. There is no danger of a collision with the Earth during this encounter. The object, designated 2004 FH, is roughly 30 meters (100 feet) in dia
