Kepler-56b
Kepler-56b is an Exoplanet located roughly 2,800 light years away. It is slightly smaller than Neptune and orbits its parent star Kepler-56 and was discovered in 2012 by the Kepler Space Telescope.
Planetary Orbit
Kepler-56b is about 0.1082 AU away from its host star.[1] About one-tenth of the distance between Earth to the Sun, making it even closer to its parent star than Mercury and Venus, it takes 10.5 days for it to complete a full orbit around Kepler-56.[2] Further research shows that Kepler-56b's orbit is about 45° misaligned to the host star's equator. Later radial velocity measurements have revealed evidence of a gravitational perturbation but currently it is not clear if it is a nearby star or a third planet.
Both Kepler-56b and Kepler-56c will be devoured by their parent star in about 130 and 155 million years.[3] Even 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]
