Detailed explanation-1: -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. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago.
Detailed explanation-2: -meteorite: A meteoroid, especially one that has hit Earth’s surface. asteroid: A rocky object that orbits the sun and has an average size between a meteoroid and a planet. comet: An object made mostly of ice and dust, often with a gas halo and tail, that sometimes orbits the sun.
Detailed explanation-3: -Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
Detailed explanation-4: -Asteroids are small rocky planetoids. while comets are formed of frozen gases held together by rocky and metallic material.
