This image shows an artist's rendering of a planet whose discovery was announced by NASA in September 2011. It is the first ever example of a "circumbinary planet" i.e. one that orbits two stars. This has led to it being dubbed "Tattooine" after the fictional circumbinary planet from the Star Wars movie franchise.

Formally, its name is ___-16(AB)-b, where the word in the blank is shared with its binary star, which gets its name from the NASA spacecraft that was used to study it. The spacecraft was named for a famous German astronomer.
