What is above stratosphere?

Above the stratosphere lies the mesosphere, which extends from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface. This layer is characterized by decreasing temperatures with altitude and is where most meteoroids burn up upon entering the Earth's atmosphere. Above the mesosphere is the thermosphere, which extends to about 600 kilometers (373 miles) and contains the ionosphere, where auroras occur and where the International Space Station orbits.
