Lunar Orbits and Moon Phases

Lunar Orbits and Moon Phases

• Using geometry, we can calculate which part of
  the moon is seen at which position.
• This simulation can be modified to show other
  aspects of Earth Science that are influenced by
  Moon Orbits, such as tides, eclipses, ect.
• Another aspect that could be modeled with this in
  combination with a variant of Molecular Dynamics
  is the birth of the moon due to an impactor.
