a planet
The most numerous bodies in the solar system are asteroids. There are estimated to be millions of them, with most of them located in the asteroid belt between Mars and Jupiter. They vary in size from small rocks to large bodies several hundred kilometers in diameter.
William Herschel invented the word "asteroid". Various people have named asteroids as they have been discovered.
It has been observed.
An asteroid is a rocky object in space. It may be a broken part of a planet. The smallest observed asteroids are 10 meters in size . There may be many asteroids smaller than this but they can not be detected yet and also have not been observed yet.
As of October 2009 around 450,000 asteroids have had at least two days observation, with approx. 397,000 with calculated orbits, and around 222,000 with complete orbits. Several hundred thousand asteroids have been discovered and given provisional.

Numerous asteroids are in constant motion around the earth, infinitely tracing their orbits. Occasionally some will collide or break down and fall as bits of meteor to Earth.
Asteroids.
An asteroid is known as a minor planet that orbits the sun. As of 2010 there have been 530,091 asteroids discovered.
William Herschel invented the word "asteroid". Various people have named asteroids as they have been discovered.
It has been observed.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
These are asteroids. They all belong to the Asteroid Belt, which is located between the planets of Mars and Jupiter.
