| Men have always been interested in
the moon because it is the biggest and brightest object
in the sky at night. In fact, it is really quite
small. It looks big because it is so near to us. It is only about
400,000 kilometers away. It is
nearer to us than any other heavenly body
in space. Although the moon looks
bright, it does not have any light of its own. It only reflects
the sun's light. The moon looks about the same size as the sun, but
the sun is really 400 times bigger and 400 times farther
away.
The moon travels around the earth at about 384,000 kilometers
an hour. Days and nights on the moon are much longer than on the
earth. One day, or one night, on the moon is as long as two weeks
on the earth. In the daytime the moon is much hotter than the earth.
It reaches a temperature
of 120 ℃. The nights are much colder: -150℃. On the moon things
are not so heavy as they are
on the earth. Something that weighs
one kilogram on the earth would
weigh only about 160 grams on the moon.
