Kepler-1981 and Its Jupiter-Like Planet
Kepler-1981 is a star 2150 light-years away with a mass of 1.07 solar masses, a radius of 1.27 solar radii, and a temperature of 5880 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this star.
Kepler-1981 b is a Jupiter-like planet discovered by transit in 2023, the same method in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. It has an orbital period of 454 days and a radius of 9.23 Earth radii, larger than Earth's. Jupiter-like planets exceed 4 times Earth's radius, and its period is the time it takes to complete one orbit.
