Usually chunks of rock that has broken off a moon, planet, etc. However, it may also be chunks of garbage ejected from a space shuttle/rocket.
No. Asteroids are basically the leftovers from the formation of the solar system. They are material that never formed a full-fledged planet.
astronomers believe that asteroids were formed by a colision with much larger body near mars and thay formed asteroid belt
masive craters formed and the asteroids shatered thanks for reading this
element
Asteroids are pieces of rock that are similar in composition to the material that formed the planets in our solar system. They are remnants from the early stages of solar system formation and can provide clues about the processes that led to the formation of planets.
It is thought that Asteroids are leftover material from unfinished planets.
Actually generally speaking Asteroids are heavily composed of high density rock. Dust and Ice are generally the properties of a Comet mostly because they aren't formed near the sun.
They formed naturally, as material in the nascent solar disk coalesced. We can tell this by the pock marked surfaces of the planets, asteroids, and moons.
Asteroids and Meteorites
The asteroids are destroyed on impact and their material becomes part of the Moon.
Saturn's rings where formed by the comets and asteroids with the strong gravitation pull .
Asteroids Minerals Asteroids are made of Rocks,Craters and other Asteroids So .... most sciientist bielieve they are remanings of planets not formed
