![]() ![]() As asteroids smash into each other, they produce crumbly debris-meteoroids. Many meteoroids are formed from the collision of asteroids, which orbit the sun between the paths of Mars and Jupiter in a region called the asteroid belt. The fastest meteoroids travel through the solar system at a speed of around 42 kilometers (26 miles) per second. Different meteoroids travel around the sun at different speeds and in different orbits. Meteoroids are even found on the edge of the solar system, in regions called the Kuiper belt and the Oort cloud. They orbit the sun among the rocky inner planets, as well as the gas giants that make up the outer planets. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system. By studying different types of meteorites, scientists can learn more about asteroids, planets and other parts of our solar system.īecause asteroids formed in the early days of our solar system nearly 4.Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. The collection acts as a meteorite library for scientists. NASA’s Johnson Space Center has a collection of meteorites that have been collected from many different locations on Earth. When they land on Earth, they are called meteorites.Ī scientist investigates a meteorite that landed in Sudan's Nubian Desert in 2008. In fact, sometimes they survive their trip through Earth’s atmosphere and land on the Earth’s surface. 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. ![]() Read on to find out more and learn the difference between asteroids and comets, meteoroids and meteorites, and more!Īn asteroid is a small rocky body that orbits the Sun.Ī close-up view of Eros, an asteroid with an orbit that takes it somewhat close to Earth. A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth’s atmosphere.
