TATOOINE, eat your heart out. The fictional planet in Star Wars that orbits two suns stands to be upstaged by a quadruple star system 150 light years from Earth that may host a planet.
The system, called HD 98800, consists of two pairs of stars in which the partners in each pair orbit one another and the pairs in turn travel around each other. Observations by the Spitzer Space Telescope show two concentric rings of dust around one of the pairs, which suggests a planet may be circling there.
