          Description Kepler-47(AB) is a multiplanetary system orbiting a binary star. This is the first system of its kind. One of the binary stars is a Sun-like star, the other one is roughly one-third the size of the Sun. The orbital period of the binary is 7.45 days.edit Kepler-47(AB) is a multiplanetary system orbiting a binary star. This is the first system of its kind.
