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]
