The Wide Area Search for Planets, a consortium of British universities, discovered a new planet they have dubbed WASP-17. The planet orbits in the reverse direction as the star it revolves around, which is the opposite of every other known planet in the universe.

“Newly formed solar systems can be violent places,” Astronomer David Anderson of Britain’s Keele University said in a press release. “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.”

Located 1000 light years from Earth, WASP-17 is twice the size of Jupiter. The team discovered the planet via cameras that monitor hundreds of thousands of stars.
