Abstract: While long anticipated in both in science and science fiction, the existence of a planet orbiting a pair of normal stars was not firmly established until the discovery of Kepler-16. With that single discovery, many questions soon arose about the nature of circumbinary planets: What kinds of orbits, masses, and radii could they have? What kinds of binary stars can host planets? How common are they? Since 2011, nine more transiting Kepler circumbinary planets have been discovered, and several more candidate systems are under investigation. While still few in number, the sample is becoming large enough that some intriguing patterns are starting to emerge, regarding the planets' radii, orbits, host star binary periods, and their proximity to the habitable zone. In this talk I will discuss the discovery and characterization of the Kepler circumbinary planets, the emerging trends, and present the latest discoveries and candidate systems.
