  Why does Moon have very cold and very hot temperature variations, e.g., from -190° to 110°C even though it is at the same distance from the Sun as the Earth is?  

Answer:

   The Moon is at the same distance from the Sun as the Earth is, but there is very cold and hot temperature variations, e.g., from ?190° to 110°C. This is because, Moon has no atmosphere. The atmosphere plays very important role in the temperature control. It acts as temperature buffer because it checks excessive rise of temperature during the day and excessive cooling during the night.
