was designated Kepler-14b, and this was published alongside the data and research on Kepler-14 in a June 2011 paper. Kepler-14's nature as a close binary star was almost missed by the astronomers, and would not have been known if high-resolution imaging of the star had not been undertaken. The Kepler team acknowledged that a number of transiting planets' host stars may have actually been close visual binaries, and that the assumed characteristics of the stars and their planets may be incorrect. As a result of their studies into Kepler-14, the Kepler team suggested the implementation of a high-resolution imaging campaign to re-examine transiting planet hosts, an effort which would require only a modest amount of telescope time. Characteristics Kepler-14 is a binary star whose two components are separated by at least 280 astronomical units, or the distance between the Earth and Sun. The estimated orbital period of the Kepler-14 binary system is approximated at 2800 years. The two stars are of nearly equal brightness, but the primary component is slightly brighter as it has a more visible apparent magnitude, or its brightness as seen from Earth. The primary star has an estimated mass of 1.51 times that of the Sun, and the secondary has an estimated mass of 1.39 times the Sun's mass. The Kepler-14 system is 980 parsecs (3,196 light years) from Earth. It has an apparent magnitude of 12.12, and thus cannot be seen with the unaided eye. Because Kepler-14 is so close-knit as seen from Earth, it was impossible for the discovery team to separate the two stars and analyze their characteristics as separate stars. The Kepler team analyzed their characteristics under the assumption that Kepler-14 was a single star. If Kepler-14 were a single star, it would be an F-type star with a mass of 1.512 times the Sun's, and a size that is 2.048 times the Sun's radius. As a single star, the effective temperature of Kepler-14 would be 6395 K, much hotter than the Sun, and the star's iron content would be 0.12, or 132% the amount found in the Sun. Assuming that Kepler-14's two stars formed at about the same time, their gyrochronological ages would be approximately 2.2 billion years. Planetary system Kepler-14b is a Jupiter-like planet in the orbit of the primary star of Kepler-14. The planet is 8.4 times Jupiter's mass, the equivalent of 2670 times Earth's mass. The planet is
