HD 31253 and Its Planet
HD 31253 is a star 190 light-years away with a spectral type of F8, placing it in a temperature class hotter than the Sun's G type. It has one known planet. The star's reported mass estimate is 1.23 solar masses, larger than the Sun's, and its radius of 1.71 solar radii is also larger than the Sun's. Its temperature is 5960 K, hotter than the Sun's, and its age is 3 billion years.
The planet HD 31253 b was discovered in 2010 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 197 Earth masses, a lower bound on its true mass and larger than Earth's, and it orbits in 466 days.
