  Why does moon have very cold and very hot temperature variations e.g., from  to  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°C to HCTC. The main reason behind this huge variation in temperature of moon is that it has no atmosphere. The atmosphere plays very important role in the temperature control. Air is a bad conductor of temphaturs thus, it acts as temperature buffer and checks excessive rise of temperature during the day and excessive cooling during the night.
