Joining in the asteroid belt.
its the comets are smaller than planets, moons, and asteroids. In order of size, usually comets < asteroids < moons < planets
William Herschel invented the word "asteroid". Various people have named asteroids as they have been discovered.
Usually comets are icy as that is why you see the icy trail, but asteroids can be icy too.
well meteors are usually boiling like comets, however asteroids are usually a formation of gas and ice but they all form in outer space
There have been about 300 identified Earth-crossing asteroids. The total number of asteroids that cross the Earth's orbit is estimated to be significantly greater than this; by one estimate, there are perhaps 1500 asteroids that are greater than 1km across, and 135,000 steroids that are greater than 100m across.
Asteroids diameter would actually usually be around the rim of 989.00 km, TRICKED YA ! I REALLY DONT KNOW
Comets : mostly ice & are often in very distant elliptical orbits. Meteoroids and asteroids are usually rocky and/or metallic, asteroids are found in the asteroid belt (between Mars & Jupiter).
Asteroids are objects smaller then planets that orbit the Sun. Meteorites are (usually) smaller objects that enter the atmosphere and reach the ground.
Asteroids comets and meteoroids all are masses of land sometimes inflamed and usually come from parts of planets hurtling through space.
usually mde up of rock minerals and metals
Comets
There are three main clusterings of asteroids in our solar system: the Asteroid Belt, the first one identified, which is composed mostly of rocky asteroids, the Kuiper Belt, which contains several dwarf planets, and many icy asteroids, and the Oort Cloud, a theoretical halo of sorts surrounding our solar system, comprised mainly of comets and icy asteroids.
