However, we can talk about different layers of the atmosphere and their approximate heights:
* Troposphere: This is where we live, and it extends about 7 miles (11 km) high.
* Stratosphere: This is where the ozone layer is, and it extends to about 31 miles (50 km) high.
* Mesosphere: This layer extends to about 53 miles (85 km) high.
* Thermosphere: This layer can extend to hundreds of miles high, but it's very thin.
* Exosphere: This is the outermost layer, and it gradually fades into space.
So, while there's no single number for the atmosphere's total height, the highest point typically considered part of the atmosphere is around 620 miles (1,000 km), where the exosphere fades into space.
