Detailed explanation-1: -An asteroid is a small rocky object that orbits the Sun. A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth’s atmosphere.
Detailed explanation-2: -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.
Detailed explanation-3: -Meteors do not land on the surface of the earth. Meteorites land on the surface of the earth. Meteoroids break down in the earth’s atmosphere, which results in the flash of light known as meteors. Meteorites are the broken meteoroids that land on the earth.
Detailed explanation-4: -Asteroids tend to have shorter, more circular orbits. Comets tend to have very extended and elongated orbits, which often exceed 50, 000 AU from the Sun. (*Note: 1 AU, or Astronomical Unit, equals the distance from the Earth to the Sun.)
Detailed explanation-5: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do.
