The compositional differences of different types of asteroids are determined by how far from the sun they were formed. They are the third most common and the biggest is called 16 Psyche and is about 120 miles wide. They make up about 17% of the total asteroids in the solar system. These are the second most common and found on the inner edge of the asteroid belt. Then there are the S-types (stony) asteroids which are made up of silicate materials and nickel-iron. These types of asteroids are very dark in appearance and are among the most ancient objects in the entire solar system, having been out there for billions of years. The C-type (chondrite) asteroids are the most common and probably consist of clay and silicate rocks. There are three types of asteroids called C, S, and M types, all with different compositions, according to Arizona State University (opens in new tab). Studying them can provide clues to how our solar system was formed. NASA's Johnson Space Center has a collection of meteorites that acts as a sort of 'meteorite library' for scientists around the world. When such a meteoroid hits the Earth's atmosphere it begins to burn up, creating a fire trail through the sky which is visible to the naked eye.īut sometimes they don't completely evaporate in the atmosphere and hit the Earth, when this happens they're called meteorites. Sometimes one asteroid can hit another, with a smaller piece breaking off and becoming something called a meteoroid. With all the chaos in the solar system caused by the gravitational pull of the sun and massive planets such as Jupiter and Saturn, things have a tendency to collide.

Galaxy: also known as the solar system a system of planets, stars and moons orbiting around a Sun Scientists believe an asteroid might have caused the extinction of the dinosaurs.F3 comet Neowise blazes over the skies of Northern Greece.Asteroid: a large body in space made of rock and minerals.

Meteor: small pieces of rock or minerals that have broken off a larger asteroid.Comet: a large body in space made of rock, ice and frozen gas.When this happens, thousands of little pieces chip off the asteroids. Sometimes asteroids collide or crash into one another. Luckily for the people of Chelyabinsk the meteor exploded in the air and didn’t hit the ground and explode, if it did it would have wiped out the town. The massive shock wave damaged thousands of buildings and injured over 1500 people. In 2013 in area of Russia called Chelyabinsk a meteor over 20 m wide exploded in the air.Most meteorites are small, but larger ones have landed on cars or houses, causing damage.Most of them burn up, but if they land on Earth, they are called meteorites. Meteors enter the Earth’s atmosphere every day. The meteors travel through space and occasionally become caught by a planet’s gravitational pull. Sometimes asteroids collide or crash into one another.Scientists estimate that a massive asteroid hit earth about 65 million years ago wiping out the dinosaurs.Ceres is the largest asteroid and is about 950 km wide.Asteroids are found in the Asteroid Belt between Mars and Jupiter. Keep reading to find out more all about comets, meteors and asteroids. Comets orbit at the very edge of the galaxy, past Pluto.This tail can be seen in the night sky as a bright, quickly-moving light. This melting process causes bits of dust and debris to trail behind the comet. As comets travel close to the Sun, some of the ice melts off and becomes a gas. Fun Facts about Comets, Meteors and Asteroids for Kids Some are only a few feet in size, while others are a mile or more long. Comets, meteors and asteroids are too small to be planets. First, they’re believed to be remnants of the materials that created the Sun and the planets. Comets, meteors and asteroids have several things in common.
