Asteroid Passes (Just) 65,000 Miles From Earth

An anonymous reader writes "Discovered a day before its closest approach to Earth, Asteroid 2013 LR6 came within roughly 65,000 miles of the planet as it flew over the Southern Ocean of Tasmania, Australia at 12:42 a.m. EDT on June 8. Despite being more than half the size of the one that exploded over Chelyabinsk, Russia in February, the 30-foot-wide asteroid posed no threat, according to NASA."

    To be fair, the object that hit Chicxulub posed no risk for any of it's near Earth passes either.... until it did.

    While this object is fairly small, it passed about 1/4 of the distance to the moon from us. If we were intelligent, we'll keep track of it so we can plot to see if it will ever hit us; if we blindly think it poses no risk, it may slap us in the face in the future.

    As for NASA stating that it posed no risk in passing us that close, i can both understand the humor in their statement, as well as them feeling the need to after the complete and utter bullshit hysteria that anything more than a gnat farting 10 miles away causes in some of the truly idiotic of our species (see: all the lame ass, end of the world bullshit ever contrived by mental midgets, or the con-men taking advantage of the mental midgets).
