The Asteroid Apophis: Could It Hit Our Planet?

This assteroid, discovered in 2004, will fly very close to Earth in 2029.

An asteroid, called Apophis 99942 (Apophis was an evil Egyptian god) was discovered in 2004.

This asteroid is interesting to many astronomers. Trajectory calculations show that in 2029 Apophis will fly only 30,000 to 40,000 km from the Earth.

The asteroid won't hit the Earth, but planet's gravity will affect its trajectory and in 2035 Apophis will probably hit the our planet. That is the biggest danger for us in past 200 years. Even if asteroid will flies a safe distance away from Earth, it can be bad for our planet.

Apophis isn't very big. Its diameter is only 390 meters, but when it hits the Earth, there will be an explosion 100,000 times bigger than the Hiroshima's atomic bomb.

It would be even more dangerous if Apophis falls into the ocean. A huge tsunami would destroy many populated coasts. Scientists suggest thinking about Earth's protection. There are plans to send a spaceship with a navigation system into the asteroid and watch its orbit.

Risk of impact? 1 in 45,000, according to NASA: http://neo.jpl.nasa.gov/risk/a99942.html

That's not the same as 'probably' hitting our planet.

I'm not rushing off to get my offshore drilling team together again with these kinds of odds.

That looks like one of those asteroids that shares Earth's orbit. I forget the technical term for them. They tend to become synchronized with the Earth and don't generally pose a risk.

What? are we getting hit by a monster hemeroid?

That picture makes it look like it will plow directly into Venus, not Earth.

if the earths gravity does affect the astroid all it will do is swing the astroid out of the solar system. that is... if another planet doesntdo it first. and if not it will just hit venus like matt said.

The piss poor english makes me realize this is a credible threat. God help us.

The risk with this asteroid is that it's not yet known if it will fly through the "keyhole" in 2029 -- that is, a fairly narrow range of positions in which the Earth's gravity will deflect it into a collision course for the 2035 encounter. If it misses the keyhole, it'll miss the Earth in 2035 and (according to those who track this stuff and have the supercomputers to predict orbits that far out) for at least the next century afterward -- and, now being a known object with, by then, a *very* well known orbit, we'll have lots of warning if it becomes a threat later.

The concern at present is that, in practice, we won't know if it's going to hit the "keyhole" until after the fact, which would then give us at most six years to deflect it away from impact -- and during most of that time, it'll be far enough away from Earth to be pretty difficult to reach with anything but a robotic probe. The time to work on deflecting this body is *now*, when we still have a couple decades; there have been arguments that we shouldn't risk deflecting it *into* the keyhole, but with, say, ten years to push/pull it after spending twelve years developing the spacecraft to do the job, it should be possible to (for instance) deflect it into a for-sure impact on the Moon or push it into an orbit that won't intersect that of Earth for centuries or longer.

the term for objects that share earth's orbit is "trojan", with 5 stable points, forward and aft of the planet.

this was forseen in the bible code prophecies
#11 by Chris, Jun 15, 2007
Right... several years after the earth is destroyed (2000 according to nostradamus?) it will be hit by a large meteor.

NASA can claim ownership and sell the rights for some corporation to put their name on it.

Why worry, the world's gonna end in the year 2012 anyway.
#14 by Ron Kuczenski, Jun 15, 2007
I agree that we need to react to this situation when it arrives in 2029. At the rate of advancement in technology we’ve been seeing there should be ways to deflect it (like in an original Star Trek episode) or blow it to pieces (Armageddon).

The map seems to indicate that its orbit is traveling between the inside of Venus’s orbit and outside Earth’s. It will only be a matter of time before it will collide with Venus, the Moon or Earth. Even though this is fairly big (about four football fields in area) there are many other pieces of rock that crosses Earth’s orbit that may be bigger. The knowledge gained from handling this one may be invaluable if a threat from a much larger one shows in the future.

lol the world is not going to end in 2012.. its just a rumor someone started to get the least bit of attention..
#16 by David, Jun 15, 2007
Why do they make this look like a real news article?
I'm changing my home page! The headline looks like a real article, but the author could hardly write a coherent sentence. It's a joke.

Learn English grammar... then report the apocalypse. This is the typical crap you can find on at Netscape.com. They used to be good before the radical alarmists took over.
#18 by Grizzly, Jun 15, 2007
Actually, a7xfail, the correlation to the year 2012 is not a rumor. There are many articles on the subject, many relating to the aztec and mayan calendars..... not 2035, now THAT's a rumor......LOL.....
#19 by aaron, Aug 17, 2007
alll i gott to say is someone VERY smart better think of something in the next 29 years before something happens because i wanna live until iam 90.... NOT 45!!!!
#20 by Anonymus, Oct 15, 2007
I say we must take drastic action. I see that NASA didn't give US any information on this. WE NEED TO DO SOMETHING! Not just wait like we are doing now. OUR PLANET DEPENDS ON US!
#21 by flav, Oct 17, 2007
This is Asteroids that will hit the Earth possible the end of the world because their are Bible refrence to it.
#22 by sam, Mar 21, 2008
NASA needs to do something now.... we have the tech that has been proven to exist in our missiles.. we have to reconfigure it to move the asteroid and not destroy it.. make a lunar base... that way it can see the asteroids we can't! WAKE UP, HOUSTON WE DO NOW HAVE A PROBLEM ESPECIALLY WITH THE SPECULATION A LARGE COMET COULD HIT IN 2012....should we be concerned.. ahh, yeah NASA.
#23 by Tad Crisuliaus, Mar 31, 2008
It would be nice to hear Nasa commment on this. As it is now, we are the blind leading the blind here. What do we know?

I do worry it could wipe us out. But i guess this can't go on forever anyway can it?
think about it.

German schoolboy, 13, corrects NASA's asteroid figures: paper
Nico Marquardt used telescopic findings from the Institute of Astrophysics in Potsdam (AIP) to calculate that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth, the Potsdamer Neuerster Nachrichten reported.

#25 by cole, Apr 17, 2008
I have reaserched apophis for a long time andi have never seen anything like it
#26 by Zenka, Apr 17, 2008
Don't wory everybody. We have Bruce Willis for this ;)

BERLIN (AFP) - A 13-year-old German schoolboy corrected NASA's estimates on the chances of an asteroid colliding with Earth, a German newspaper reported Tuesday, after spotting the boffins had miscalculated.

Apophis wouldn't smash into Venus. Based on the diagram, by the time apophis gets to where venus is in that picture, venus would probably be opposite that.
Anywho, if Apophis gets too close, Chuck Norris will just roundhouse kick it out of the solar system! Duh.

I work for a program that tracks objects and paths conflicting with earths path of movement. What is known now is this, Earth is infact in the path of a large object, 2012 is the predicted or estimated impact year. This will be at a minimum, The End Of Mankind. I am running for the shores and getting a team together to do some high tech drilling, ( Bruce Willis ) will be the lead man in this operation. On a serious note this is infact as real as it can be, joking aside have children, get married, rob banks, underage drink. I will see you all in the after life and laugh with the dinosaurs, it will be great times my friends.

My monitor is ruined. It is full of corrective red marks trying to render this news/article coherent to English speakers. A run of the mill word processor could have easily identified the spelling problems.
I are reporting on on assterhoid hitted Earth on 2029.

All you have to do is look at the craters in our moon to find out how lucky we are and how good it is to have a moon
