Sometimes meteoroids don’t vaporize completely in the atmosphere. However, when you see a meteor, it’s in our atmosphere. You can see a comet even when it is very far from Earth. That vaporized ice and dust become the comet’s tail. But comets are made of ice and dust-not rock.Īs a comet’s orbit takes it toward the Sun, the ice and dust begin to vaporize. However, these two things are very different.Ĭomets orbit the Sun, like asteroids. Image credit: NASA/JPLīecause meteors leave streaks of light in the sky, they are sometimes confused with comets. This photo was taken during the Perseid meteor shower, which happens each year in August. If a meteoroid comes close enough to Earth and enters Earth’s atmosphere, it vaporizes and turns into a meteor: a streak of light in the sky.īecause of their appearance, these streaks of light are sometimes called "shooting stars." But meteors are not actually stars.Īt certain times of the year, you might be lucky enough to see more meteors in the sky than usual. This can cause small pieces of the asteroid to break off. Sometimes one asteroid can smash into another. Most asteroids in our solar system can be found in the asteroid belt, between Mars and Jupiter. For example, some asteroids orbit the Sun in a path that takes them near Earth. But they can also hang out in other locations around the solar system. Most asteroids in our solar system are found in the main asteroid belt, a region between Mars and Jupiter.

The photo was taken by NASA’s Near Earth Asteroid Rendezvous - Shoemaker spacecraft in 2000.

A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth’s atmosphere. A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth’s atmosphere, creating a streak of light in the sky.Īn asteroid is a small rocky object that orbits the Sun.
