Kepler-23c is a Neptune-sized exoplanet orbiting the star Kepler-23, located in the constellation Cygnus.3 The planet is 3.12 times wider than the Earth2 and is 0.189 Jupiter masses.3 The planet was discovered using data taken from the Kepler space telescope.1 It is likely a gas giant. The planets Kepler-23b and d both reside in the same planetary system.
