Detailed explanation-2: -The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material.

Detailed explanation-3: -They survived the tumultuous formation of our solar system 4.5 billion years ago, and the sometimes-chaotic aftermath. An asteroid is mostly rock and dust, with some ice in the mix, while a comet is mostly ice, with some rock and dust.

Detailed explanation-4: -Some come from comets, others from asteroids, and some even come from the Moon and other planets. Some meteoroids are rocky, while others are metallic, or combinations of rock and metal. When meteoroids enter Earth’s atmosphere, or that of another planet, like Mars, at high speed and burn up, they’re called meteors.

Detailed explanation-5: -Comets are made of dust, ice, and rock materials, while asteroids are composed of rocky materials and metals. Both celestial bodies were formed 4.6 billion years ago. Asteroids were formed much closer to the sun where it was impossible for the ice to remain solid.
