The Birth of the Moon

My Astronomy paper for my final will be based on this concept.  This is a topic that has always fascinated me.  I will not only delve into how the moon was created but the fact that Earth has an iron core that Mars is lacking.  And the fact that this collision made it so that Earth was large enough to allow her to stay hot enough to keep her atmosphere unlike Mars.  This makes me realize why I love Science so much.
