meteorite

A meteorite is the solid portion of a meteoroid that survives its fall to Earth, or some other body. Meteorites are classified as stony meteorites, iron meteorites, and stony iron meteorites, and further categorized according to their mineralogical content as shown in the table (see individual entries for each of these types). They range in size from microscopic to many meters across. Of the several tens of tons of cosmic material entering Earth's atmosphere each day, only about one ton reaches the ground – an object's survival chances depending on its initial mass, speed of entry, and composition. Incoming meteoroids with masses between 10^(–6) g and 1 kg tend to burn up completely as meteors. Smaller objects are dramatically slowed down without being incinerated and fall as a continuous, gentle, invisible rain of micrometeorites. Larger objects, up to 1,000 tons, are decelerated to a lesser extent, fall through the lower atmosphere at high speed, causing them to glow brightly as a fireball.
