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.

2019年4月17日 · Astronomers have discovered a third planet in the Kepler-47 system, securing the system’s title as the most interesting of the binary-star worlds. Using data from NASA’s Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two ...

2024年10月25日 · 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.

2025年1月17日 · NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.

Kepler-47c (also known as Kepler-47(AB)-c and by its Kepler Object of Interest designation KOI-3154.02) is an exoplanet orbiting the binary star system Kepler-47, the outermost of three such planets discovered by NASA's Kepler spacecraft.

2012年8月28日 · The two planets of Kepler-47, the first transiting circumbinary system - a system with more than one planet orbiting a pair of stars. Kepler-47b, on the right, has three times the radius of earth and orbits the pair of stars in less than 50 days while Kepler-47c is thought to be a gaseous giant, slightly larger than Neptune with an orbital period o

2019年4月17日 · Three planets are orbiting two suns in the Kepler-47 system. Astronomers discovered the third planet, a Neptune-to-Saturn-size world lurking between two previously known planets.

Astronomers have found a third planet circling a pair of stars in the Kepler 47 system. An artist's illustration shows the three planets of the Kepler 47 system. The large middle planet represents the newly discovered Kepler 47d.

Using data from NASA’s Kepler space telescope, a team of researchers led by astronomers at San Diego State detected in April 2019, the new Neptune-to-Saturn-size planet, dubbed Kepler-47d, orbiting between two previously known planets.

2019年4月17日 · With its three planets orbiting two suns, Kepler-47 is the only known multi-planet circumbinary system. Circumbinary planets are those that orbit two stars. The planets in the Kepler-47...
