Planets Around HD 35843
HD 35843 is a star 227 light-years away with two known planets. The star is 2.5 billion years old, has 0.94 solar masses, and a radius of 0.897 solar radii. Its temperature is 5670 K, cooler than the Sun's, and its radius is smaller than the Sun's.
HD 35843 b was discovered in 2025 by the radial velocity method, which measures the wobble a planet's gravity induces in its star. It has a minimum mass of 5.84 Earth masses and an orbital period of 9.9 days, the shortest year among the listed planets. Its minimum mass is larger than Earth's.
HD 35843 c was also discovered in 2025, by the transit method, which detects the dip in starlight as a planet crosses its star. It is Neptune-like, with a mass of 11.3 Earth masses, a radius of 2.54 Earth radii, and an orbital period of 47 days, the longest among the listed planets. Its mass and radius are larger than Earth's, and its mean density is 3.81 g/cm³, 0.691 times Earth's.
