HD 1461 and Its Two Known Planets
HD 1461 is a G5V star 76.5 light-years from Earth. A G-type dwarf is Sun-like, and this one is estimated to be 7.12 billion years old, with a mass of 1.03 solar masses and a radius of 1.11 solar radii. Its temperature is 5770 K. Both planets orbit this star, and both were found by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion.
The two planets are HD 1461 b and HD 1461 c. HD 1461 b was discovered in 2010, and HD 1461 c in 2015. HD 1461 b has a minimum mass of 6.44 Earth masses and an orbital period of 5.77 days. HD 1461 c has a minimum mass of 5.59 Earth masses and an orbital period of 13.5 days. Among the listed planets, HD 1461 b has the shortest year by reported estimates and the largest minimum mass, while HD 1461 c has the longest year and the smallest minimum mass.
