HD 23127 and Its Planet
HD 23127 is a star 306 light-years away with a spectral type of G5, making it a Sun-like dwarf. It is 4.51 billion years old, has 1.21 solar masses, a radius of 1.49 solar radii, and a temperature of 5840 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet, HD 23127 b, was discovered in 2006 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 485 Earth masses, roughly 1.53 times Jupiter's mass, and it completes an orbit every 1210 days.
