The first confirmed binary star found to have a planet revolving around both stars (a circumbinary planet, the previous one was uncertain and detected using astrometry), located 200 ly away. It is often compared to the Tattoine of Star Wars. It is a Saturn sized world thought to be of rocky and gaseous composition. It is at Venus-like distance from the center of gravity, but because the stars are so dim (70% SM and 20% SM), lies at the outermost portion of the habitable zone. A moon could potentially be habitable. The stars orbit each other every 41 days.
