CoRoT-23 is a star located in the constellation Serpens at a distance of about 1956 light-years from us. At least one planet revolves around the star.
CoRoT-23 is a yellow dwarf main sequence star similar to our Sun. Its solar mass is 1.098 and its solar radius is 0.86.[1] The surface temperature is about 5900 kelvin.
One planet has been discovered orbiting CoRoT-23, CoRoT-23b. [2]
The planet may be in an unstable orbit and subject to merger with the host star in the future.[3]
