HD 11506 and Its Three Known Planets
HD 11506 is a star 167 light-years from Earth. Its spectral type is G0 V, a Sun-like class, and it is a single-star system. The star is estimated to be 5.4 billion years old, with a mass of 1.19 solar masses and a radius of 1.38 solar radii. Its temperature is 6060 K. Three planets are known to orbit this host.
HD 11506 b was discovered in 2007 by the radial velocity method and has a minimum mass of 1530 Earth masses, or roughly 4.8 times Jupiter's mass, with an orbital period of 1620 days. HD 11506 c was found in 2008, also by radial velocity, and has a minimum mass of 127 Earth masses and an orbital period of 224 days. HD 11506 d was discovered in 2022 by radial velocity, with a mass of 4070 Earth masses, roughly 12.8 times Jupiter's mass, and an orbital period of 26500 days.
Among these planets, HD 11506 c has the shortest orbital period, at 224 days, while HD 11506 d has the longest, at 26500 days. The star's reported mass estimate is larger than the Sun's, its radius estimate is also larger, and its temperature is hotter than the Sun's.
