Meteors usually burn up in the mesosphere, in aâ¦ltitude from 75 km  to 100 km in earth atmosphere.as long as the meteor is small enough it burns up in earths atmoshere but rarly they dont burn up and make it though. Meteors burn up when the start coming through the atmosphere.
Next up, the mesosphere starts just above the stratosphere, 31 miles (50 km) above the surface and extends up to 53 miles (85 km). The mesosphere is the coldest layer of the atmosphere with temperatures averaging -130Â° F (-90Â° C). Most of the meteors that burn up in the atmosphere do so in the mesosphere.
