Yes there are multiple, but none are likely to hit in our lifetime. But there is a small chance of one hitting us. But its not like one of those doomsday things when its almost as big as earth. It would be devastating though.

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.
When did an asteroid collide with Mercury?
An asteroid(s) impacted with Mercury many times in it's early formation.
Can an asteroid destroy the earth?
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
What is the name of the asteroid that will be near earth in 2029?
99942 Apophis is an asteroid where initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029.Later observations concluded that the asteroid would miss the Earth.The chances are now set at a one in 3 million that it will hit Earth.
The earth been destroyed by a asteroid?
No, if the Earth was destroyed by an asteroid we would not be living today.
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.
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.
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".

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!)
How does an asteroid fall on earth ex. does the asteroid just go rolling until it reaches earth?
The Earth itself is in free-fall, falling around the Sun in its orbit. Asteroids behave the same way; they are falling in their orbits around the Sun. Sometimes, they collide, like cars on the freeway.
When did an asteroid collide with Mercury?
An asteroid(s) impacted with Mercury many times in it's early formation.
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.
What is the name of the asteroid that hit planet earth that set perfect orbit and rotation as we know it?
It was not an asteroid. It was a planet. The name starts with an 'M'.
Can an asteroid destroy the earth?
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
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.
