    Astronomers (天文学家) can tell just how hot the surface of the　　 moon gets. The side of the moon toward the sun gets two degrees hotter　　 than boiling water. The night side reaches 243 degrees below zero.

　　     In an eclipse (日蚀、月蚀), the earth's shadow falls on the moon.　　 Then the moon's temperature may drop 300 degrees in a very short time.

　　     A temperature change like this cannot happen on the earth. Why　　 does it happen on the moon? Astronomers think that the surface of the　　 moon is dust. On the earth, rocks store heat from the sun. When the　　 sun goes down, the rocks stay warm. But the dust of the moon cannot　　 store heat. So when the moon gets dark, the heat goes away quickly.　　 The moon gets very cold.
