"Although the moon has enthralled observers for aeons, planetary scientists have struggled to trace its ancestry. The manned lunar landings of the Apollo program were supposed to help by collecting hundreds of pounds of moon rocks. Three perfectly respectable theories for lunar origin had been proposed. All that was needed to choose among them was a chunk or two of the object in question. But the lunar samples may as well have been made of blue cheese." (DISCOVER) This article theorizes that the moon was formed from a chunk of the Earth that was broken off when a planetary object slammed into it.
