Earth's natural satellite - the Moon

  • Orbiting many of the planets are  natural satellites, called moons
  • Our Earth has one moon. 
  • It moves in an orbit round the Earth.
  • It is held in this orbit by the pull of  Earth's Gravity.
  • It goes around the Earth in an anti-clockwise direction. 
  • The Earth also spins in an anti-clockwise direction at the same time from west to east.
  • It takes one lunar month (28 days) to complete one orbit of the Earth.
  • The Moon is a dead object. 
  • It has no light of its own. 
  • As it goes around the Earth we see the moon surface reflecting the Sun's light
  • It looks different at different times of the month, changes its shape. 
  • It has phases.  The phases are about 4 days apart.  See animation and diagram below.
