Kepler-763 and Its Three Planets

Kepler-763 is a star located 3140 light-years away. It is 4.79 billion years old, with a mass of 0.84 solar masses, a radius of 0.8 solar radii, and a temperature of 5170 K. The star's reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.

Three planets orbit Kepler-763. Kepler-763 b, an Earth-like planet discovered in 2016 by transit, has an orbital period of 1.2 days and a radius of 1.22 Earth radii, which is larger than Earth's. Kepler-763 c, also Earth-like and discovered in 2023 by transit, has an orbital period of 4.1 days and a radius of 1.42 Earth radii, which is larger than Earth's. Kepler-763 d, a Super-Earth discovered in 2023 by transit, has an orbital period of 6.5 days and a radius of 1.67 Earth radii, which is larger than Earth's.

Among the listed planets, Kepler-763 b has the shortest orbital period at 1.2 days and the smallest radius at 1.22 Earth radii. Kepler-763 c has the second-shortest orbital period at 4.1 days and the second-smallest radius at 1.42 Earth radii. Kepler-763 d has the longest orbital period at 6.5 days and the largest radius at 1.67 Earth radii.
