Where do asteroids that fall to the earth come from?

Answer 1

small pieces of debris that are from other comets, asteroid's, etc colliding together
Meteoroids are formed by; Scientists look at what they know--the form and composition of meteorites as the see it in the laboratory and the form and composition of the universe as they see it through their telescopes. They then make a guess--pose a hypothesis--as to how meteorites formed. They test the hypothesis by trying to prove it false. Following are the current theories of how meteorites formed:

Answer 2

Asteroids that fall to Earth typically come from the asteroid belt located between Mars and Jupiter, though some may also originate from other regions in the solar system. These asteroids can be nudged out of their orbits by gravitational interactions with planets or collisions with other asteroids, eventually leading them to intersect with Earth's orbit and potentially impact the planet.

Answer 3

As far as I know, no particular precautions need to be taken; it is not the way it is depicted in Science Fiction stories on television. The asteroids are very far apart from one another, and the chances of hitting one are fairly slim.

Answer 4

Asteroids and Comets are the leftovers from the formation of our Solar System. When we think of the Solar System, we tend to think of the Sun, its eight planets, and their moons. But there is much more going on here than meets the eye. The empty spaces of our solar system are littered with small objects known as asteroids and comets. These objects can be thought of as the leftovers of the Solar System. There are chunks of rock, ice, or both that are believed to have formed from the primordial matter that originally created the Solar System. Comets have been known since ancient times. This is because they tend to announce their arrival in grand style. As the Sun heats their cores, their long, glowing tails can be seen for weeks as the circle the Sun. These objects were once thought to be omens of disaster. Several comets return like clockwork on a cycle that brings them back every few years. Comet Halley, perhaps the most famous, returns every 76 years. Unlike comets, asteroids tend to come and go unnoticed. They are usually only seen when they enter the Earth's atmosphere. A few of the asteroids in our solar system are large enough to be observed from Earth. The first to be observed was Ceres. It was discovered by a Sicilian monk named Giuseppe Piazzi in 1801. Since that time, thousands of these objects have been discovered. Hope this helps. Good luck!

Answer 5

Here is a perfect explanation pulled from a wiki page:

The asteroid belt formed from the primordial solar nebula as a group of planetesimals, the smaller precursors of the planets. Between Mars and Jupiter, however, gravitational perturbations from the giant planet imbued the planetesimals with too much orbital energy for them to form into a planet. Collisions became too violent, and instead of sticking together, the planetesimals shattered. As a result, most of the main belt's mass has been lost since the formation of the Solar System. Some fragments can eventually find their way into the inner Solar System, leading to meteorite impacts with the inner planets.

Answer 6

In order to reach the earth's surface, the asteroid has to first enter the earth's atmosphere. This happens when the asteroids path intersects the earth's orbit around the sun. Second, the asteroid has to reach the earth's surface without eroding. As the asteroid enters the atmosphere, the high velocity of the asteroid increases the drag force, thus causing more resistance and erosion. Generally, asteroids become small before hitting the earth's surface.

Answer 7

Asteroids are formed from the same dust and gas that formed the sun and the planets in our solar system
by sand and dust in space and rocks

Answer 8

Astronomers think that asteroids are material that jupiter's gravity prevented from forming into a planet.

Answer 9

The "asteroid belt" is the theory of left over matter from when our galaxy and planets , were created.

Answer 10

Asteroids are big or small chunks of other planets that have been knocked off by other asteroids when they collide.
