What's the Difference Between Asteroids, Comets, and Meteors? We Asked a NASA Expert

The video explains the differences between asteroids, comets, and meteors. Asteroids are rocky objects found mainly in the asteroid belt between Mars and Jupiter. Comets are composed of ice and dust, and develop tails when near the Sun. Meteoroids are small fragments from asteroids or comets, and when they enter Earth's atmosphere, they become meteors, often seen as shooting stars. If a meteor reaches the ground, it is called a meteorite. The video concludes by summarizing these differences.
