Kepler-1256: A Distant Star and Its Lone Planet
Kepler-1256 is a star located 2910 light-years away. It is 3.72 billion years old, has a mass of 1.17 solar masses, a radius of 1.36 solar radii, and a temperature of 6130 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this star.
That planet is Kepler-1256 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-1256 b has an orbital period of 12.4 days, the time it takes to complete one orbit, and a radius of 1.49 Earth radii, which is larger than Earth's. As an Earth-like planet, it stays within 1.5 times Earth's radius.
