HD 28254 and Its Planet
HD 28254 is a star 180 light-years away with a spectral type of G1 IV/V, and one planet has been found in its orbit. The star's mass is 1.06 solar masses, its radius is 1.48 solar radii, and its temperature is 5660 K. Its mass and radius are both larger than the Sun's, while its temperature is cooler.
The planet HD 28254 b was discovered in 2010 by the radial velocity method. That technique tracks the wobble a planet's gravity induces in its star's motion, and repeated wobbles reveal the planet and its orbital period. HD 28254 b has a mass of 1210 Earth masses and an orbital period of 1330 days. Its mass is larger than Earth's and roughly 3.8 times Jupiter's mass.
