collisions with other small planets and a veritable plethora of asteroid 
impacts. The prevailing theory about the formation of the moon is called the 
giant impact hypothesis: the theory goes that a Mars-sized object, known as 
Theia, crashed in to the young Earth. What was left was Earth, and its moon. </blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/05/did-multiple-mo.html"><P>"The giant impact that likely led to the formation of the Moon launched a lot of material into Earth orbit, and some could well have been caught in the Langrangian points," -points in space where the gravity between two objects cancels the other out, said says study team member Lissauer.   Their theory places small moonlets, or Trojans, in Earth’s orbit, for up to 100 million years.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/05/did-multiple-mo.html">Over time, gravitational tugs from other planets would have eventually altered
