Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. So, the atmosphere of the moon is both hot and cold at the same time. When the sun shines, the temperature rises up to 260 F (127 C), which is more than the temperature of boiling water. When there is no shining sun, the temperature comes below -280 F (minus 173 C).
