  4. Moon Formation Hypothesis • The impact theory of the moon's formation was first proposed in the mid-1970s and is now widely accepted. • According to this hypothesis, Earth's moon formed from a collision between the early Earth and a Mars-sized object. • Both Earth and its impactor had already formed iron cores before the collision, leaving their outer layers relatively iron-poor.

  7. Rotation • The action of turning around an axis or center • The rotation of the Moon – or a lunar day – lasts around 27.3 days. • This is the same amount of time the Moon takes to complete one orbit around the Earth. • Because the rotation of the Moon and the length of its orbit are exactly the same, the Moon always presents the same face to the Earth.

  8. Revolution • the action by a celestial body of going round in an orbit or elliptical course
