Gamma Sextantis, Latinized as γ Sextantis, is a binary star [12] system in the equatorial constellation of Sextans. The combined apparent visual magnitude of the system is 5.05, [2] which means it is faintly visible to the naked eye. The annual parallax shift is 11.75 mas, [1] indicating a distance of around 280 light years.
The two components orbit each other with a period of 77.55 years and a high eccentricity of 0.691. The orbital plane is inclined by 145.1° to the line of sight from the Earth. [1] With a visual magnitude of 5.6, [5] the brighter component A is an A-type main sequence star with a stellar classification of A1 V. [5] The fainter companion B has a classification of A4 V [5] with a magnitude of 6.0. [5] Their combined spectral matches a classification of A0/1 V [4] and their angular separation 0,4 arcseconds, so for the observation a telescope with at least 30 centimetres aperture is require.
There is a magnitude 12.28 companion star C at an angular separation of 36.9 arc seconds along a position angle of 333°, as of 2000. This separation has increased from 30.0 arc seconds in 1834. The proper motion of this star differs from the Gamma Sextantis AB system, having components μα = −29 mas/yr and μδ = +5 mas/yr. [13]
