HD 92788 is a G-type star located approximately 113 light-years away in the constellation of Sextans. It is more massive and slightly smaller than the Sun with high metallicity.
Planetary system
An extrasolar planet was discovered orbiting this star in 2001.[3]
The star rotates at an inclination of 8+14
−8 degrees relative to Earth.[4] It is probable that this planet shares that inclination.[5][6]
