HD 148164: A Distant Star With Two Known Worlds
HD 148164 is a star 252 light-years away with two known planets. Its spectral type is F8, placing it among the hotter, more massive stars than the Sun. The star is 2.41 billion years old, contains 1.21 solar masses, spans 1.34 solar radii, and has a temperature of 6030 K. Its radius and temperature both exceed the Sun's.
Both planets were discovered in 2018 using the radial velocity method, which detects the gravitational wobble a planet induces in its star's motion. HD 148164 b has a minimum mass of 391 Earth masses and an orbital period of 329 days. HD 148164 c has a minimum mass of 1640 Earth masses and an orbital period of 5060 days. The minimum mass of each planet is larger than Earth's, and the minimum mass of HD 148164 c is roughly 5.16 times Jupiter's mass. Among the listed planets, HD 148164 b has the shortest year by reported estimates, while HD 148164 c has the longest; b also has the smallest minimum mass and c the largest.
