Why would scientists want to know if an asteroid is on a course to collide with earth in 20 years?

If an asteroid were to hit Earth, it could do HUGE damage. It was the changes to Earth after an asteroid hit that killed off the dinosaurs. But if we knew about an asteroid heading our way long enough ahead of time, maybe we could change it's course enough to make it miss, and save millions of lives.

Has scientists ever found an asteroid that will crash into Earth in the future?
No.No.No.No.
Will asteroid 2012 DA14 hit earth in 2013?
No. The asteroid has passed, having missed Earth by about 17,000 miles. That's fairly close, but scientists new it would miss by about that much.
What happened when an asteroid hit earth?
What happened when an asteroid hit the Earth is debatable but many scientists believe that this is what may have wiped out the dinosaurs. Some people believe that the asteroid created a dust cloud that covered the planet and caused a winter that froze most life.
What would happen if an asteroid on a collision course with Earth would get blown up in outer space?
It is FAR easier to change the direction of an asteroid than to blow it up. All that is needed to accomplish the former is to nudge the asteroid a little off its collision course with Earth, and this could be done with some small explosions on the side of that asteroid. Blowing up an asteroid would be a complete waste of energy.
Is Earth inside or outside of the asteroid belt?
From the sun it goes Mercury, Venus, Earth, Mars, ASTEROID belt, Jupiter, Saturn, Uranus, Neptune, Pluto (although no longer classed as a planet). So the earth is inside the orbit of the asteroid belt.

How many years does it take an asteroid to happen?
An asteroid to happen? Asteroid cannot 'happen'. It can collide with earth, or any other object with mass, though.
Why do astronomers search for near earth asteroids?
Near-Earth asteroids have some potential to collide with Earth. The effects of an impact, even from a relatively small asteroid, could be devastating. So, scientists are working to find objects that might collide with Earth. If one is shown to be a substantial danger, then strategies for deflecting it to miss earth may be discussed.
How does path of the asteroid compare to the path the earth travels?
It doesn't. In an estimated 23 years, a belt of asteroids will collide with the earth.

No.No.No.No.
What are NEAs?
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
What planet did Earth once collide with?
Earth did not collide with a planet. If Earth collided with another planet, it would have been smashed to smithereens and wiped from existence, then over billions of years the debris would have formed into a series of lifeless moons. It is believed however that a large-ish object, most likely a small moon or large asteroid, did collide with the Earth. The debris from that impact is believed to have created the moon that orbits Earth. So, a planet did not collide with Earth. But it's possible a small moon or large asteroid did. This is only a theory, it has not been scientifically proven. The theory is called the "giant impact hypothesis".

No. The asteroid has passed, having missed Earth by about 17,000 miles. That's fairly close, but scientists new it would miss by about that much.
What do scientists believe happened after an asteroid struck earth million years ago?
The dinosaurs died.
Is there a 2012 asteroid?
yes, the asteroid tauntless is a space rock which crosses orbits with earth every 'so many' years, it will come close to the planet but no actually collide with it though, (or let's hope it doesn't!)
When plates of the earth move apart scientists says they?
It's simple, when the plates collide, the crust of the earth wrinkles forming mountains.
If a black hole or an asteroid hit earth what will happend to the ocean?
A black hole would eventually swallow up the entire Earth. An asteroid would provoke great catastrophes - depending, of course, on the mass of the asteroid.
