Kepler 47

This places Kepler-47 c well within the classical quothabitable zone,quot defined as the range of distances from the host stars where liquid water could persist on the surface of an Earth-like planet . While Kepler-47 c is probably a gas giant and thus not suitable for life, its location is notable as it demonstrates that circumbinary planets

We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that of Earth, respectively. The binary star consists of a Sun-like star and a companion roughly one-third its size, orbiting each other every 7.45 days. With an orbital period of 49.5 days, 18 transits of the inner planet

Kepler-47 is a binary star system in the constellation Cygnus located about 3,420 light-years 1,050 parsecs away from Earth.The stars have three exoplanets, all of which orbit both stars at the same time, making this a circumbinary system.The first two planets announced are designated Kepler-47b, and Kepler-47c, and the third, later discovery is Kepler-47d.

Kepler-47 is a roughly 3.5-billion-year-old system located 3,340 light-years from Earth. One of its stars is quite sunlike, but the other is considerably smaller, harboring just one-third the mass

Kepler-47 b is a Neptune-like exoplanet that orbits a G-type star. Its mass is 2.07 Earths, it takes 49.5 days to complete one orbit of its star, and is 0.2877 AU from its star. Its discovery was announced in 2012.

Kepler-47b also known as Kepler-47 AB b and by its Kepler Object of Interest designation KOI-3154.01 is an exoplanet orbiting the binary star system Kepler-47, the innermost of three such planets discovered by NASA's Kepler spacecraft.The system, also involving two other exoplanets, is located about 3,400 light-years 1,060 parsecs away.

The planets in the Kepler-47 system were detected via the quottransit method.quot If the orbital plane of the planet is aligned edge-on as seen from Earth, the planet can pass in front of the host stars, leading to a measurable decrease in the observed brightness. The new planet, dubbed Kepler-47d, was not detected earlier due to weak transit

The eclipsing binary Kepler-47 is the first system detected to have multiple circumbinary planets Orosz et al. 2012. The binary consists of a Sun-like star and a companion roughly one-third its size, orbiting each other every 7.45 days. The planets were detected using transit photometry when each planet transits the stars of the binary.
