possibility that their host stars were binary systems; the only way that this was definitely known in the case of Kepler-14 was through the use of high-resolution imaging. If the less prominent portion of the Kepler-14 binary system had not been detected, Kepler-14b's mass would have been incorrect by nearly 60%, and its radius too small by about 10%.

was used to find the centroid, the point in space around which both of the Kepler-14 stars orbit. Analysis of the collected data determined which component of the binary star system was the site of the transit signal, and, additionally, that the transit signal came from the primary star in the system

The authors of Kepler-14b's discovery paper noted that, had they not discovered that Kepler-14 was indeed a binary system, the parameters for Kepler-14b would have been extremely inaccurate. They noted that other planets discovered using radial velocity measurements might not have accounted for the

Kepler-14b's host star is the primary (A) component of the Kepler-14 binary system. However, because the binary system is so closely knit, it was impossible at the time of Kepler-14b's discovery to distinguish the characteristics of each individual star. If the Kepler-14 system was an individual

Kepler-14 is a binary star system, which means that it is actually composed of two gravitationally bound stars that orbit a common point in space. The system is composed of a primary star, Kepler-14A, and a dimmer companion star, Kepler-14B. When the stars were observed, while searching for the

In other words, the planet is 8.4 times more massive than Jupiter, but only 1.136 times Jupiter's size. This equates to a high density, which is measured at 7.1 g cm. According to the 453:
