HD 127506: A Nearby K-Type Dwarf and Its Planet
HD 127506 is a K3.5 V star located 73.5 light-years away. The "V" in its spectral type marks it as a main-sequence dwarf, and its class places it among the cooler, less massive stars. It has a mass of 0.73 solar masses, a radius of 0.736 solar radii, and a temperature of 4600 K, all smaller or cooler than the corresponding values for the Sun. One planet is known to orbit this star.
That planet, HD 127506 b, was discovered in 2022 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 27.3 Earth masses, a lower bound on its true mass, and it completes an orbit every 65.8 days.
