yes they are. when the planets were first made, they crashed together and the astroids broke off the planets
A solar system
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.
The gas planets are much more massive than the terrestrial planets and therefore have stronger gravity. It is believed that as they formed many of their moons formed around them much like the planets formed around the sun. Other moons are likely captured asteroids and comets.
Planets, moons, asteroids.
its the comets are smaller than planets, moons, and asteroids. In order of size, usually comets < asteroids < moons < planets
The Sun and the asteroids.
Asteroids and Comets
Basically absence... also comets, meteors, asteroids, planets, moons, satellites, shuttles and space stations, planets and moons.
No. There are more than that. There are currently 173 known moons orbiting planets in our solar system and many more orbiting dwarf planets, asteroids, and comets.
Gasses & dust including all known elements.
Answer 1: Asteroids are formed by the collision of two planets breaking each into small pieces and floating off into space Answer 2: Asteroids are formed when planets are absorbed and crushed inside a black hole. The pieces of the planet are then ejected from the backend of the black holes into space as asteroids.
