HD 92788 is a star in the equatorial constellation of Sextans. It has a yellow hue but is too dim to be visible to the naked eye, having an apparent visual magnitude of 7.31.[2] The star is located at a distance of 113 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −4.5 km/s.[4] Two planets have been found in orbit around the star.[5]

This is a G-type main-sequence star with a stellar classification of G6V.[3] It is estimated to be around eight billion years old and is spinning with a rotation period of 31.7 days.[6] The star has a similar mass to the Sun and is slightly larger in radius, with a high metallicity. It is radiating 1.25[1] times the luminosity of the Sun from its photosphere at an effective temperature of 5,722 K.[1]
