Does any one know about the 99942 Apophis asteroid to hit earth in 2036?

Question

there are alot of websites talking about this and if u dont belive me go to yahoo or google and search 99942 Apophis.

Here are a few sites telling you info about the asteroid:

What im asking is i want to know your comment and thoughts on hat you have about this. now this asteroid is not 100% sure that its gonna hit but there is a 100% chance it will come so close that it will hit or at least become visible to the naked eye.

please post your comments or questions about this and let me know what you think of this.

one of the links up there dident come out right but here it is now:

i have also heard that blowing up the asteroid is far beyond our tech but setting it off corse by hitting it on the side mabye? can set it of corse alot

Answer 1

scientists say that on the early moring of Friday April 13th 2029 the asteroid 99942 Apophis will pass Asia and North Africa giving observers an extremely rare chance to c 99942 Apophis passing the Earth @ a distance of 20,000 miles. the obsevers will b able to c this rare event take place with a naked eye.

the 99942 Apophis is about 1,000 feet in diameter. its said that sumthin like this and coming this close to the Earth only happens once every 1,500 years.

wen scientists first discoverd 99942 Apophis in 2004, they gave it a 1-40 chance of this happening in 2029. after scientists studied 99942 for a while, this prediction became obsolete. now they say that it will pass the Earth on Friday April 13th 2029.

scientists state that bfore this event will occur wen it passes the earth in 2029, it will make a trip around the sun bfore headin bacc towards.

once it gets bacc in the earth vicinity, there is a 1-10,000 chance of enterin the "key hole" that is only a 1/2 mile in diameter and then collidin into Earth on Friday April 20th 2036 allowing mankind on earth to bcome extinct.

Answer 2

The 2029 pass of (99942) Apophis is presently predicted to be at 5.93 +/- 0.09 Earth radii, thats about 38,000 km. The along track uncertainty is +/- 570 km. Observers in Europe and Africa are best placed to see it moving across the sky on April 13, 2029. Maximum visual magnitude is about 3.5 so should be clearly visible to the naked eye.

It is, however, not likely to hit us in 2036, in fact it may be no where near us then. The problem is that the 2029 pass alters the orbit and what happens depends very precisely on the exact path taken in the 2029 pass. If Apophis passes through a particular 600m region of space in 2029 then it will come back and hit us in 2036. However this region is presently around 1000km from the predicted position. However, I mentioned before that the uncertainty was 570 km so there is still the possibility that further data will move the predicted position into the 2036 "keyhole". But extra data could easily move the predicted position elsewhere. What it should do is further reduce the uncertainty so if the current predicted position remains about right and the uncertainty drops to 200 km or 100 km then we should be able to say for sure that it won't go through the keyhole and hit us in 2036.

Answer 3

The odds of 99942 Apophis' 2029 pass setting it up for a collision in 2036 are about 1 in 233,000.

Answer 4

According to the current Wikipedia entry, 1 in 45,000 odds of 2036 impact. If it did, estimated 880 megaton equivalent. Largest nuke ever exploded was 58 megaton, Krakatoa eruption about 200 megatons. Very bad for nearby life, but in a geographic perspective, no big deal.

Answer 5

Probability: 1:50,000
Energy: 400 megatons TNT
Dates: April 13, 2036 and April 13, 2037
(Neither day is a Friday, thank our lucky stars.)

Answer 6

Not even close

Answer 7

We will nuke the asteroid, by indirect impace using the force to alter its projectory.
