HD 92788 is a G-type star located approximately 107 light-years away in the constellation of Sextans. It is more massive and slightly smaller than the Sun with high metallicity.

Planetary system[edit]

An extrasolar planet was discovered orbiting this star in 2001.[1]

The star rotates at an inclination of 8+14
−8
degrees relative to Earth.[2] It is probable that this planet shares that inclination.[3][4]
