What are Asteroids?


Asteroids are minor planets, especially those inside the solar system and orbiting the sun.

There are millions of asteroids, many thought to be the shattered remnants of planetesimals bodies within the young Sun's solar nebula that never grew large enough to become planets.
The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter Trojans).
