The irons, the stony-irons and the stones.
Iron meteorites as the name states are composed of almost solid nickel-iron. Often there are mineral inclusions in iron meteorites, but they amount to a small percentage of the mass. Three main subgroups of irons have been recognized. Meteoroids are one of the three main types of objects flying around our solar system. Find out where the meteoroids are located in our solar system with help from an experienced educator in this free video clip. Part of the Video Series: Space, Planets & Moons. Description. Even hundreds of years ago when the first real scientific studies of meteorites were done it was clear that there are three main types of meteorites. Each of these families of meteorites today includes many subgroups but irons, stony-iron, and stones remain as the three main groups. A meteoroid is smaller than an asteroid. It would range in size  from a grain of sand up to a boulder. Most meteoroids that enter  earth's atmosphere are about the size of a … grain of sand, and these  become meteors. Meteoroids travel in variety of orbits and speeds around the Sun.  They can enter the earth's atmosphere at speeds ranging from 11  km/s to 72 km/s. There are three words that refer to the same object in different situations: meteoroid, meteor, and meteorite. But, over time the differences seen among the ever growing number of these visitors has led to many more categories than three. At the present there are approximately fifty types of meteorites recognized. They still fall mainly into the three original families; the irons, the stony-irons and the stones. There are now a host of sub-groups within each main type. Just as there are different types of asteroids, there are also different types of meteorites. There are actually three main types. These are 1  -. Stony-Just basic stony, rocky material, often with a burned crust on the outside. So these are the main three travelers of the solar system, and to answer your question, meteoroids can be found everywhere in the solar system.
