Thermosphere
nothing it is as far as it can go
it is about 500-650 kilometers above earth's surface.
Troposphere Stratosphere Mesosphere Thermosphere
The atmosphere begins at the surface of the Earth and extends to space. The upper levels are the thermosphere (up to about 500-650 km altitude) and the exosphere (generally from 500 to 2000 km altitude but is nearly a vacuum).
Thermosphere is a layer in the Earth's atmosphere between mesosphere and exosphere.
The altitude of the Thermosphere is from about 50 miles to 310 miles. The Thermosphere is the biggest of all layers of the Earth's atmosphere.
The thickness of the Thermosphere is 210 kilometers. It is 300 Km. away from Earth.

Thermosphere
The thermosphere, which is a region of the Earth's atmosphere, is above the mesosphere. The thermosphere helps the planet because it absorbs most of the X-ray and UV radiation from the Sun. The thermosphere extends from 53 miles to about 621 miles above the Earth's surface.
