Experts Keeping Close Eye on Asteroid

Quote:

(April 14) -- An asteroid the size of a 25-story building will come within 18,000 miles of Earth on April 13, 2029 -- closer than the communication satellites that orbit the planet, Discovery.com reported.
The asteroid, called Apophis, has only a 1 on in 45,000 chance of colliding with Earth. But it will then be back for another shot seven years after that.
It's hard for astronomers to determine what kind of threat Apophis poses in 2036 because its orbit will be bent by gravity during its 2029 flyby, Discovery reported.
During the 2029 visit, the asteroid is expected to be visible to the naked eye at night.
Apophis, which was discovered in 2004, is about 210 to 330 meters, or 690 to 1080 feet, in diameter, according to NASA.
In comparison, the asteroid thought to have wiped out dinosaurs 50 million years ago was 6.2 miles in size. In more recent history, an asteroid that was about 50 meters, or 164 feet, exploded over Siberia, an unpopulated part of Russia, in 1908. It torched or blew down trees in an 800-square mile area, Discovery reported last year.
"As things get bigger, the amount of devastation goes up dramatically," but so does the length of time between occurrences, Nick Kaiser, the lead scientist of a new University of Hawaii asteroid-hunting project, told Discovery.
A half-mile diameter object hitting Earth would be likely to cause a global catastrophe, Kaiser said. But events like that happen only every couple of million years.
This object is predicted to come historically close, about a 1 in 800 year event, NASA said.
Scientists expect to know more detail about Apophis' future orbits in 2013 and 2021, when the asteroid will come within 9 million miles of Earth. That will put it close enough for radar studies.

Wow - I'll be ready to retire and the world will end ... great!

"As things get bigger, the amount of devastation goes up dramatically,"

Tell me about it!

omg I just went back in time to the Delta Sig frat house. That was some cool shit to have way back then, and everyone played it all the time! I STILL suck at that game.

7700 HA...beat that! :blush:

can't now...playing duck hunt

Wow, that site has a ton of games. Sweet.

Now say it 3 times fast.

Eh, you all fear my score of 7700 in ASSteroids. My gauntlet has been dissed.

no, no...you fukkers don't have till 2029.

2012!!! 2012!!!

I don't know why you all dismiss this. Your collective faces will be pretty red come 2012.

(no, Sheldon, not CUM 2012...come 2012)

I thought that score seemed low. ;)

I didn't want to burst your bubble, but since you brought it up AGAIN, I beat that score with my first ship ... twice

See, I said I've always sucked at that game. I knew anyone could beat that score! :)
