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.

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 will collide with earth that provides evidence of earth's inner composition?

Meteorites that originate from the asteroid belt can collide with Earth, carrying evidence of Earth's inner composition. By analyzing these meteorites, scientists can study the interior structure and composition of our planet.


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".


Why would scientist 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.

Can an asteroid go through the earth?

No, an asteroid cannot physically pass through the Earth due to its solid structure. If an asteroid were to collide with the Earth, it would impact the surface, causing significant damage depending on its size and speed.


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.


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'.


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!)


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 big is the asteroid 2004 MN4 that is supposed to hit Earth on Friday April 13 2029?

Asteroid 2004 MN4, also known as Apophis, is approximately 370 meters (1,214 feet) in diameter. It was initially thought to have a small chance of impacting Earth in 2029, but further observations have ruled out that possibility. The asteroid will come close to Earth but is not expected to collide with our planet.
