Kepler-23 is a G-type main-sequence star about 2,860 light-years (880 parsecs) away in the northern constellation of Cygnus, the swan. With an apparent visual magnitude of 13.5,[3] it is too faint to be seen with the naked eye. This star is similar in mass and temperature to the Sun, but is larger and more luminous.[5][4] Kepler-23 is orbited by three known exoplanets.[6]
