Space

It takes about  27 days  for  the moon to  orbit  the  earth. The moon looks bright, but it actually a dark and rocky place.It looks bright only when the sun ‘s light reflects, or bounces off of it.

Mercury  does not have a moon. Mercury is hard to see from earth because its too               close  to the sun. Mercury is only a little  bigger than earth’s moon.mercury and Venus are the only big plants in our solar system.
