However, if the rock you've found isn't at all close to black or brown in color, then it is not a meteorite. Some collectors enjoy the appearance of beautiful iron forged in the elements. The stronger the magnet, the more likely you can seek out these tiny micrometeorites and pull them off the ground. In the same vein as sending a space probe to an asteroid or comet and collecting a sample but infinitely cheaper finding a meteorite whose incoming trajectory is known can reveal fresh information about the structure and composition of a distant region of the solar system. The magnet itself is on the underside. When you picture a meteorite, you probably imagine a massive hunk of space rock hurtling its way through Earths atmosphere. You can perform a color streak test on a rock you find by scraping it across a piece of unglazed porcelain. These meteors fly around the solar system and sometimes collide into other celestial bodies, including the Earth. Crobium is a type of zirconium that is formed by cooling microgravity-generated droplets of melted rock into spherical discs. "Furthermore, the dry conditions in all of these regions (even Antarctica) help preserve the specimens i.e., they are less altered by liquid water," Rubin told Life's Little Mysteries.
