I love the movies and some of my favorites involve the “what-if” scenarios of a catastrophic collision between the Earth and an impending asteroid. There’s “Armageddon” starring Bruce Willis, a great ensemble cast in “Deep Impact”. Also, there’s the 1950s B-movie classic “When Worlds Collide”. Well, guess WHAT?? An asteroid is rapidly approaching the Earth! Obviously, this is not a really big deal because we, in the media would be on the air 24/7 if it was. According to astronomers, there is no need for concern, but the space rock will make an exceptionally close approach to our planet early on Monday, July 3, passing just beyond the Moon’s average distance from Earth.
As it gets closer to us, these same star-gazers will use radar to figure out where it is. If you have a very good telescope, you can camp out in the back yard and spy it for yourself at around 12:25 am this coming Monday.
This chunk of space, designated 2004 XP14, was discovered on Dec. 10, 2004 by the Lincoln Laboratory Near Earth Asteroid Research (LINEAR), a continuing camera survey designed to keep watch for asteroids that may pass uncomfortably close to our home. This asteroid is a member of a class of asteroids known as Apollo, so named because their orbit crosses the Earth. Scientists don’t exactly know how big it is, but preliminary estimates show it could be from a quarter mile to just over a half-mile wide.
To get a better handle on XP14, astronomers plan to utilize NASA's 230-foot diameter Goldstone radar, the largest and most sensitive antenna in its Deep Space Network. Located in California’s Mojave Desert, the Goldstone antenna has been used to bounce radio signals off other Near-Earth asteroids many times before, and it is now being readied to “ping” 2004 XP14 on July 3, 4 and 5.
So, there’s no need to panic, right? Did I mention that astronomers don’t know how big it is? These are the same geniuses who sometime forget to carry the one! Oh well, let’s hope they are right.
