HD 64114 and Its Lone Known Planet
HD 64114 is a G7 V star 103 light-years from Earth. Its spectral type marks it as a Sun-like, main-sequence dwarf. The star holds 0.99 solar masses, a radius of 0.908 solar radii, and a temperature of 5600 K. Its radius is smaller than the Sun's, and its temperature is cooler. One planet is known to orbit this host.
That planet, HD 64114 b, was found in 2019 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 17.8 Earth masses, a lower bound on its true mass and larger than Earth's. It completes one orbit every 45.8 days.
