Kepler-56c is a hot Jupiter[2] (a class of exoplanets) orbiting the star Kepler-56, located in the constellation Cygnus. It was discovered by the Kepler telescope in October 2013. It orbits its parent star only 0.17 AU (16 million mi; 25 million km) away, and at its distance it completes an orbit once every 21.4 days.[1] Its orbit is significantly misaligned with its parent star's equator.[1]

Both Kepler-56b and Kepler-56c will be devoured by their parent star in about 130 and 155 million years.[3] Further research shows that it will have its atmosphere boiled away by intense heat from the star, and it will be stretched by the strengthening stellar tides.[3]
