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.
The mesosphere of Venus extends from 65 km to 120 km in height, and the thermosphere begins at around 120, eventually reaching the upper limit of the atmosphere (exosphere) at about 220 to 350 km. The exosphere is the altitude at which the atmosphere becomes collisionless. The mesosphere of Venus can be divided into two layers: the lower one between 62â73 km and the upper one between 73â95 km. In the first layer the temperature is nearly constant at 230 K (â43 Â°C).
