Kepler-68 is a Sun-like main sequence star. It is known to have at least three planets orbiting around it. The outermost planet has a mass similar to Jupiter but orbits within the habitable zone.[2]

Planetary system[edit]

Currently, three planets have been discovered to orbit around Kepler-68. Two of the innermost planets were discovered by planetary transit method. Follow-up Doppler measurements helped to determine the mass of Kepler-68b and helped to discover Kepler-68d. [3]
