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.


Although initially there were concerns that this asteroid might possibly impact Earth later this century and thus merit special monitoring, further analysis of its orbit has since ruled out any such collision, at least in the foreseeable future.


Size not known


Asteroid 2004 XP14 is a member of a class of asteroids known as Apollo, which have Earth-crossing orbits. The name comes from 1862 Apollo, the first asteroid of this group to be discovered. There are now 1,989 known Apollos.


The size of 2004 XP 14 is not precisely known. But based on its brightness, the diameter is believed to be somewhere in the range of 1,345 to 3,018-feet (410 to 920 meters). That's between a quarter mile and just over a half-mile wide.


Due to the proximity of its orbit to Earth [Map] and its estimated size, this object has been classified as a “Potentially Hazardous Asteroid” (PNA) by the Minor Planet Center in Cambridge, Massachusetts. There are currently 783 PNAs.


The latest calculations show that 2004 XP14 will pass closest to Earth at 04:25 UT on July 3 (12:25 a.m. EDT or 9:25 p.m. PDT on July 2). The asteroid's distance from Earth at that moment will be 268,624-miles (432,308 km), or just 1.1 times the Moon's average distance from Earth.


Spotting 2004 XP14 will be a challenge, best accomplished by seasoned observers with moderate-sized telescopes.


On April 13, 2029, observers in Asia and North Africa will have a chance to see another asteroid, but without needing a telescope. Asteroid 99942 Apophis, about 1,000 feet (300 meters) wide, is expected to be visible to the naked eye as it passes within 20,000 miles (32,000 km). Astronomers say an asteroid that large comes that close about once every 1,500 years.


Observing plans


As 2004 XP14 makes its closest approach to Earth, astronomers will attempt to gauge its size and shape by analysis of very high frequency radio waves reflected from its surface.


Such radar measurements of the exact distance and velocity of the asteroid will allow for precise information on its orbit. From this scientists can also discern details of the asteroid's mass, as well as a measurement of its density, which is a very important indicator of its overall composition and internal structure.


Astronomers plan to utilize NASA's 70-meter (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.


Augmenting the Goldstone observations will be radar observations scheduled at Evpatoria in the Ukraine, commencing several hours prior to the July 3 observations at Goldstone.


Editor's Note: A SPACE.com viewer's guide for 2004 XP14 will be presented in Joe Rao's weekly Night Sky column on Friday, June 30


Got my hopes up over nothing. :headbang:

Wait for 2029. Apophis will be enough to make people wet their pants.

They recalculated the orbit. 2036 seems more probable.

Either way, I'm betting that it's actually going to get pulled in by Earth's gravity, and land on something hard.

An asteroid full of space nymphos gets attracted by Earth's gravity and land on something hard.

Then everybody turns into a mutant or something, just to keep it interesting.

Given that asteroids can be as much as 600 miles in diameter, I think the word 'huge' here is a tad misplaced. Certainly it's on the high side of the average, but hardly 'huge'.

Do the aliens have extra orifices?

That's close and anything near .5 KM or 1 KM is not nice.

What might do quite a bit of damage to, but not annihilate earth, could wipe out our moon.. and we'd be screwed. I think I'd rather us get hit.

We don't have the capability to send a nuclear weapon to hit it.

Painting them white is actually considered a much more feasible option for diverting such bodies.

Aside from that, are you suggesting that putting one of these...

...in one of these...

... is a good idea?

I was wondering what you were meaning when you said paint it white.. thought at first it was some sort of sarcasm I didn't get .. but

" A more novel idea is to paint the surface of the asteroid white. This should change the amount of solar energy it radiates and change its course. However, the amount of paint required could be huge. "
