Detailed explanation-1: -Asteroids, meteors, and comets actually have the same basic composition. They are made of rock, dust, and sometimes ice that was leftover from the formation of the planets. Both comets and asteroids orbit the Sun. Meteors are created when comets leave behind some dust and small rocks as they complete their orbits.
Detailed explanation-2: -What’s the difference between a meteor, meteoroid, and meteorite? They’re all related to the flashes of light called “shooting stars” sometimes seen streaking across the sky. But we call the same object by different names, depending on where it is.
Detailed explanation-3: -An asteroid is a small rocky object that orbits the Sun. A comet is a ball of ice and dust that obits the Sun. A meteoroid is a small piece of an asteroid or a comet. A meteor is a streak of light in the sky that appears when a meteoroid burns up upon entering Earth’s atmosphere.
Detailed explanation-4: -Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do.
