The thermosphere is the thinnest layer of the Earth's atmosphere. It extends from about 53 miles (85 km) to 375 miles (600 km) above the surface. The air density in the thermosphere is less than 1% of that at sea level.
Here are some additional facts about the thermosphere:
- The thermosphere is where the International Space Station orbits.
- The temperature in the thermosphere increases with altitude, reaching up to 1,500°C (2,732°F).
- The thermosphere is home to the aurora borealis (northern lights) and aurora australis (southern lights).
