An international joint research team composed of the Yunnan Astronomical Observatory of the Chinese Academy of Sciences, the Hamburg Observatory of Germany, the Xi’an Jiaotong-Liverpool University and the Nanjing Institute of Astronomical Optics and Technology of the Chinese Academy of Sciences discovered a “super-Earth” Kepler-725c with a mass 10 times that of the Earth in the habitable zone of the sun-like star Kepler-725 for the first time using the transit intermediate time variation (TTV) technology.
Kepler-725c—the newly discovered non-transiting planet—orbits a G9V host star. With an orbital period of 207.5 days and a semi-major axis of 0.674 AU, it receives roughly 1.4 times the solar radiation that Earth does. During part of its orbit, the planet lies within the host star’s habitable zone, making it a potential candidate for habitability.
