How high is the sky?

Let’s explore each atmospheric layer and uncover what makes our sky so mesmerizing.

Atmospheric Layers

Sky Diagram

Troposphere

Extends from the Earth’s surface up to about 8–15 km (5–9 mi). Weather happens here.

Stratosphere

15–50 km (9–31 mi) above sea level. It contains the ozone layer.

Mesosphere

50–85 km (31–53 mi). Meteors burn here before reaching Earth.

Thermosphere

85–600 km (53–373 mi). Home to the ionosphere, vital for radio signals.

Exosphere

Starts around 600 km (373 mi) and fades into space at ~10,000 km (6,200 mi).

Factors Influencing Sky Perception

Atmospheric conditions like clouds, pollution, and sunlight can change how we perceive height, clarity, and color.
