Prepare to Duck

One of the nearly 2000 asteroids known as "Apollos" because they have earth crossing orbits will give us a near miss Sunday. This asteroid (2004 XP14) is a pretty big one and is esitmated at over a half mile in diameter. It is one of the 983 asteroids that are considered "Potentially Hazardous" due to the close proximity of its orbit.

An asteroid possibly as large as a half-mile or more in diameter is rapidly approaching the Earth. There is no need for concern, for no collision is in the offing, 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.

Astronomers will attempt to get a more accurate assessment of the asteroid's size by “pinging” it with radar.

And skywatchers with good telescopes and some experience just might be able to get a glimpse of this cosmic rock as it streaks rapidly past our planet in the wee hours Monday. The closest approach occurs late Sunday for U.S. West Coast skywatchers.

The asteroid, designated 2004 XP14, was discovered on Dec. 10, 2004 by the Lincoln Laboratory Near Earth Asteroid Research (LINEAR), a continuing camera survey to keep watch for asteroids that may pass uncomfortably close to Earth.
