Our own Moon is thought to have been created when a Mars-sized planet collided with the recently formed Earth and threw up a cloud of debris. A near collision during the early, violent stage of this planetary system could well have caused a gravitational slingshot, flinging WASP-17 into its backwards orbit.” (c) http://www.neatorama.com/tag/wasp-17/ Aceasta este ipoteza actuala.
