HD 80653 and Its Two Known Planets
HD 80653 is a G-type main-sequence star 358 light-years away, with two known planets orbiting it. It is a single star, and its reported values exceed the Sun's: it has 1.15 solar masses, 1.2 solar radii, and a temperature of 5960 K. Its age is 3.3 billion years.
HD 80653 b was discovered in 2020 by the transit method. It is a Super-Earth with a radius of 1.62 Earth radii and a mass of 5.61 Earth masses. It completes an orbit in 0.72 days. Its mean density is 7.26 g/cm³, which is 1.32 times Earth's. Among the listed planets, HD 80653 b has the shortest year by reported estimates.
K2-312 c was discovered in 2023 using the radial velocity method. It has a minimum mass of 1680 Earth masses and an orbital period of 871 days. Among the listed planets, K2-312 c has the longest year by reported estimates.
HD 80653 b's radius and mass are larger than Earth's. K2-312 c's minimum mass is larger than Earth's and roughly 5.29 times Jupiter's mass.
