Kepler-1647 b
Kepler-1647b (sometimes named Kepler-1647(AB)b to distinguish it from the secondary component) is a circumbinary exoplanet that orbits the binary star system Kepler-1647, located from Earth in the constellation Cygnus. It was announced on June 13, 2016, in San Diego at a meeting of the American Astronomical Society. It was detected using the transit method, when it caused the dimming of the primary star, and then again of the secondary star blended with the primary star eclipse. The first transit of the planet was identified in 2012, but at the time the single event was not enough to rule out

Kepler-1647b (sometimes named Kepler-1647(AB)b to distinguish it from the secondary component) is a circumbinary exoplanet that orbits the binary star system Kepler-1647, located from Earth in the constellation Cygnus. It was announced on June 13, 2016, in San Diego at a meeting of the American Astronomical Society. It was detected using the transit method, when it caused the dimming of the primary star, and then again of the secondary star blended with the primary star eclipse. The first transit of the planet was identified in 2012, but at the time the single event was not enough to rule out contamination, or confirm it as a planet. It was discovered by the analysis of the Kepler light-curve, which showed the planet in transit.
== Characteristics == === Mass and orbit === The exoplanet is a gas giant, similar in size to Jupiter, and has an orbital period of 1107 days. This is the longest transit period of any confirmed transiting Kepler exoplanet discovered yet. It is also the largest circumbinary Kepler planet known. It is times more massive than Earth, and times Jupiter's mass.
