The Moon is approximately as far away from the Sun as the Earth is. So, it receives approximately as much heat and light from the Sun as the Earth.
During the day, the Moon's temperature is around 100 °C! During the night, the temperature goes down to about -173 °C!
Even on the Earth, the night is cooler than the day. But, the temperature difference between day and night is not so large! Finish this module to see why the temperature difference is lower on the Earth.
