Asteroids, Comets, Meteors, and Meteorites. These spacefarers are too small to be called planets and are given the names of comets, asteroids, meteoroids, and if they reach Earth, meteors or meteorites.

With so many labels, it's easy to forget which is which. Asteroids: These are the rocky and airless leftovers from the formation of planets in our solar system. They mostly orbit our sun in the asteroid belt between Mars and Jupiter and range from the size of cars to dwarf planets.

Comets: Comets are dirty space snowballs of mostly ice and dust that formed during the birth of the solar system 4. Most comets have stable orbits in the outer reaches of the solar system past the planet Neptune. Meteoroids, Meteors, Meteorites: Meteoroids are tiny asteroids or the broken-off crumbs of comets and sometimes planets.

They range in size from a grain of sand to boulders 3 feet 1 meter wide. When meteoroids collide with a planet's atmosphere, they become meteors. If those meteors survive the atmosphere and hit the planet's surface, their remains are called meteorites. At first glance, asteroids may seem like run-of-the-mill space rocks, but these ancient solar system remnants come in all shapes, sizes and flavors.

Despite their small stature the mass of all the asteroids combined is less than Earth's moon , asteroids are also called minor planets or "planetoids.

Ceres is so large, it received a promotion to the status of a dwarf planet in , the same controversial distinction given to Pluto. Most asteroids look like giant space potatoes, with their oblong shapes and surface that's pockmarked by numerous craters caused by collisions with other asteroids. Only a small number of asteroids are large enough that their gravity forms them into spheres, such as Ceres.

Most asteroids, however, are small objects only a few kilometres across. The compositions of asteroids are very similar to those of meteorites and this has led to the idea that meteorites originated in the asteroid belt. Visit Us. Search Want to search our collection?
