Kepler-29 is a Sun-like star in the northern constellation of Cygnus. It is located at the celestial coordinates: Right Ascension 19h 53m 23.598s}, Declination +47° 29′ 28.411″.[4] With an apparent visual magnitude of 15.036,[2] 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. To date the age of the star has not been determined due the 4064 light-year (1246 parsecs) distance. As of 2016 no Jovian exoplanets of 0.9–1.4 MJ have been found at a distance of 5 AU. [5]
