Kepler-5

Kepler-5 is a star located in the constellation Cygnus in the field of view of the Kepler Mission, a NASA project aimed at detecting planets in transit of, or passing in front of, their host stars as seen from Earth.

Kepler-5 is larger and more massive than the Sun, but has a similar metallicity, a major factor in planet formation.

Kepler-5 is actually the second planet-bearing star discovered during the course of the Kepler Mission, a NASA operation that seeks to discover Earth-like planets that transit, or cross in front of, their host stars with respect to Earth.

[6][7] Kepler-5 is a sunlike star that is 1.374 (± 0.056) Msun and 1.793 (± 0.053) Rsun, and is 137% the mass of and 179% the radius of the Sun.

It is, thus, a Hot Jupiter, or a gas giant that orbits near to its host star.
