}}{{Starbox end}}Kepler-107 is a star in the constellation Cygnus. It is a spectral type G2 star. A giant impact is the likely origin of two planets in the system. Kepler-107 c is more than twice as dense (about 12.6 g cm–3) as the innermost Kepler-107 b (about 5.3 g cm–3).Planetary systemKepler-107 has four known planets. {{OrbitboxPlanet begin
