HD 95544 and Its Giant Planet

HD 95544 is a G-type main-sequence star 286 light-years from Earth. Its spectral type, G3 V, marks it as a Sun-like dwarf. The star has a mass of 1.09 solar masses and a radius of 1.09 solar radii, both larger than the Sun's corresponding values, and a temperature of 5720 K, which is cooler than the Sun's. One planet orbits this host.

That planet, HD 95544 b, was discovered in 2021 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a mass of 1910 Earth masses, roughly 6.02 times Jupiter's mass and larger than Earth's, and an orbital period of 2040 days.
