Two Planets Around the Sun-Like Star HD 92788
HD 92788 is a G-type main-sequence star 113 light-years away. Its spectral type is G5 V, and it is 3.5 billion years old. This host has two known planets. The star contains 1.1 solar masses, spans 1.11 solar radii, which is larger than the Sun's radius, and has a temperature of 5770 K.
The radial velocity method revealed both worlds. HD 92788 b was found in 2000. Its minimum mass is 1200 Earth masses, roughly 3.76 times Jupiter's mass, and it completes an orbit every 326 days, the shortest year among the listed planets. HD 92788 c was discovered in 2019, has a minimum mass of 1170 Earth masses, roughly 3.67 times Jupiter's mass, and takes 11600 days to orbit. It has both the longest year and the smallest minimum mass among the listed planets.
