i've heard recently about smthing will hit the earth and destroy it after many years. tell me pls all about it

Answer 1

I suspect you have picked up the story of Asteroid 99942 Apophis. as the rumours surrounding it are rife and spread by irresponsible unresearched journalism on "Doom and Gloom" TV Channels and the gutter press,

People get garbled versions of this in which the object is a comet. a meteor, or unspecified/left vague and the common theme of all the rumours is that it "is heading straight for earth" (like an avenging Angel?) and that it will "destroy the earth and kill everyone".

A more sober account of the facts which would reveal there is only a very tiny percentage chance of an impact would of course not sell many newspapers or attract much advertising revenue to the channels that carry this scare-mongering stuff.

This is how Wikipedia summarises the situation:

"(99942) Apophis (previously known by its provisional designation 2004 MN4) is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a relatively large probability that it would strike the Earth in 2029.

Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029.

However there remained a possibility that during the 2029 close encounter with Earth, Apophis would pass through a "gravitational keyhole", a precise region in space no more than about 400 meters across, that would set up a future impact on April 13, 2036. This possibility kept the asteroid at Level 1 on the Torino impact hazard scale until August 2006.

Additional observations of the trajectory of Apophis revealed the "keyhole" would likely be missed and on August 5, 2006, Apophis was lowered to a Level 0 on the Torino Scale.

As of October 19, 2006 the impact probability for April 13, 2036 is estimated at 1 in 45,000. An additional impact date in 2037 has been identified, however the impact probability for that encounter is 1 in 12.3 million."

With those odds I for one will contnue to sleep soundly in my bed at night! What is revealing is how the old information of Dec 2004 circulates freely, even though it has been refuted and superceded by further observations and recalculation of its orbit.

Answer 2

The short answer is, you heard wrong.

The long answer is that you hear these stories quite often now days. It is only in the last 50 years or so that we realized that asteroids big enough to cause serious damage could still hit Earth. None is big enough to completely destroy Earth, but some are big enough to really mess up the planet, causing a giant explosion, earthquakes, tidal waves and vast clouds of dust that could blot out sunlight for years, causing cold weather, crop failures and so on. And it is only in the last 10 years or so that we started making a survey of asteroids in orbits that cross Earth's orbit and so have a chance of hitting Earth. Every now and then a new asteroid is discovered that looks like it might hit Earth in the next few years, but so far better measurements of the orbit have shown all those asteroids will miss. There is some chance that one we don't know about would hit, but that has always been true. There is also some chance that one we know about will hit in the distant future. Like 50,000 years in the future. It is like lightning that way. We know lightning strikes all the time but how long until it strikes your house? Nobody knows. We now know that asteroids pass Earth every year, but how long until one passes too close and actually hits? Nobody knows.

Answer 3

Nothings is predicted to hit the earth and destroy it.

Period.

Meteors have hit the earth in the past; it is believed that a meteor hit the Earth creating so much dust in the atmosphere that greatly reduced the sunshine and the temperature, thus wiping out the food source for the dinosaurs and thus wiping out the dinosaurs.

Could one hit and create similar conditions on Earth for us.
Yes. But no meteor is scheduled to do so.

Answer 4

if you are talking about the famous asteroid that wiped out the dinosaurs in Arizona? don´t worry about it. how many times in Mans history has one hit? and besides, as it stands now, we have the technology to alter the course of almost any thing coming in. we might blow it up in the process.

i put in a link. i for get how many are around the world, but the one in Arizona is most famous because it has been unaltered. and i seriously doubt it had any thing to do with whipping out the dinosaurs. Personally, i don´t believe they could breath under water.

Answer 5

I have already got 6 and it works merely effective for me because of the fact it makes me a lot much less frightened of death than maximum. yet i will desire and save my palms crossed that atheists would be in front of me so i will plss myself guffawing whilst they are on their knees screaming for God to maintain them.
