The hottest layer in Earth’s atmosphere is the thermosphere. Temperatures here can soar up to 2,000°C or even higher. However, humans wouldn’t feel this heat directly because the air molecules are so sparse that there’s little transfer of thermal energy. Satellites orbit within this layer, and the International Space Station also lies within its bounds. The high temperature results mainly from absorption of solar radiation, especially extreme ultraviolet and X-rays.
