Kepler-1399 b: A Close-In Earth-Like World
Kepler-1399 is a star located 4520 light-years away. It is 4.37 billion years old, has a mass of 0.97 solar masses and a radius of 0.96 solar radii, and its temperature is 5740 K. One planet orbits this host.
That planet is Kepler-1399 b, an Earth-like world discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1399 b completes an orbit every 1.64 days, and its radius is 1.25 Earth radii. This reported radius estimate is larger than Earth's. Earth-like describes size class, since such a planet stays within 1.5 times Earth's radius.
