Kepler-29

Sun-like star in the constellation Cygnus

Kepler-29 is a Sun-like star in the northern constellation of Cygnus. It is located at the celestial coordinates: Right Ascension 19h 53m 23.6020s, Declination +47° 29′ 28.436″.[2] With an apparent visual magnitude of 15.456,[3] this star is too faint to be seen with the naked eye. It is a solar analog, having a close mass, radius, and temperature as the Sun. Currently the age of the star has not been determined due to its 2780 light-year (850 parsecs) distance. As of 2016 no Jovian exoplanets of 0.9–1.4 MJ have been found at a distance of 5 AU. [7]

Planetary system

In 2011 an analysis of the first four months of data from the Kepler space telescope detected 1235 planetary candidates two of which orbited this star.[8] Later study of the transit-timing variations of the system lead to the confirmation of both planets.[9] The planetary orbits are lying in Orbital resonance to each other, with orbital period ratio being exactly 7:9.[10]
