Kepler47b

Kepler47b is an exoplanet orbiting the binary star system Kepler-47. It is the innermost of the four known planets in the Kepler-47 system. Discovered in 2012 by NASA's Kepler space telescope, Kepler47b is a terrestrial planet, meaning it is likely rocky. Its orbital period is approximately 4.7 days, making it very close to its host stars. Due to its close proximity, the planet is extremely hot, with surface temperatures estimated to be well above the boiling point of water.

The Kepler-47 system is unique because it hosts multiple planets orbiting two stars simultaneously. This arrangement, known as a circumbinary orbit, is relatively rare. Kepler47b's existence demonstrates that planets can form and survive in such complex stellar environments. While its extreme temperature makes it unlikely to host life as we know it, Kepler47b is a significant object of study for understanding planet formation and atmospheric conditions in binary star systems. Further observations are needed to determine its exact mass, composition, and atmospheric properties.
