HD 3765 and Its Planet
HD 3765 is a K2V star 58.5 light-years away. The spectral type identifies it as a main-sequence K-type dwarf, and its temperature of 5030 K is cooler than the Sun's. It has a mass of 0.85 solar masses and a radius of 0.79 solar radii, both smaller than the corresponding values for the Sun. Its age is 2 billion years. One planet is known to orbit this host.
That planet, HD 3765 b, was discovered in 2021 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 55 Earth masses, larger than Earth's. Its minimum mass is a lower bound on its true mass. Its orbital period is 1210 days.
