Venus the Comet

I was doing some research and I found that there are several scientific theories that mention that Venus was actually a comet that was ejected from Jupiter before it became a planet.

"Perhaps the strangest appearance of Venus in popular culture is as the harbinger of destruction in Immanuel Velikovsky's Worlds in Collision (1950). In this intensely controversial book, Velikovsky argued that many seemingly unbelievable stories in the Old Testament are true recollections of times when Venus, which Velikovsky claimed had somehow been ejected from Jupiter as a comet, nearly collided with the Earth." - http://en.wikipedia.org/wiki/Venus
