HD 137496 and Its Two Known Planets
HD 137496 is a Sun-like, G-type star located 507 light-years away. Its reported mass estimate is 1.04 solar masses and its radius estimate is 1.59 solar radii, both larger than the Sun's corresponding values. The star's temperature is 5800 K and its age is 8.3 billion years. Two planets have been found orbiting this host.
HD 137496 b is an Earth-like planet discovered by the transit method in 2021. It has a radius estimate of 1.31 Earth radii, larger than Earth's, and a mass estimate of 4.04 Earth masses, likewise larger than Earth's. Its mean density is 9.9 g/cm³, 1.8 times Earth's. It completes an orbit in 1.62 days, the shortest year among the listed planets.
HD 137496 c was discovered by radial velocity in 2021. Its minimum mass is 2430 Earth masses, a lower bound larger than Earth's and roughly 7.66 times Jupiter's mass. Its orbital period is 480 days, the longest year among the listed planets.
