Recently, an unmanned spacecraft studied the moon's craters. Surprisingly, the moon was found to have the
coldest known places in the solar system. Pluto,
which is billions of miles farther away, still gets some direct
sunlight. However, the craters on the moon do not,
resulting in a temperature around 400 degrees F (240 degrees
C) below zero. The discovery of these spots is
important. It suggests that there might be more water on the moon
than scientists originally thought.
