Asteroid Apocalypse

  1. Mar 19, 2004 #1
    PASADENA, Calif. -- A 100-foot-diameter asteroid passed close but harmlessly by Earth on Thursday, astronomers said.

    The hurtling rock passed about 26,500 miles above the southern Atlantic Ocean at 3:08 p.m. MST.

    Astronomers were continuing to observe the asteroid, 2004 FH, which was expected to be beyond the moon's orbit by early today.

    A 100-foot-diameter asteroid impacting the Terran atmosphere would produce a one-half Megaton explosion.

    This is a cool simulation of the asteroid's orbit.

    It seems to me that close shaves with asteroids are getting more common. I hear about one every two months or so.

    Already another thread on this

    The Minor Planet Center (MPC) has a regularly (like every day, maybe even every hour) updated page on NEOs - Near Earth Objects.

    "Close shaves" certainly *seem* to be getting more common! However, it's almost surely because a) the press is more readily picking the stories up, and b) we're getting much, much better at finding them. :smile:
