Delta Sextantis (δ Sex, δ Sextantis) is a solitary[10] star in the equatorial constellation of Sextans. With an annual parallax shift of 10.13 mas,[1] it lies at a distance of around 322 light years from the Sun. This star is faintly visible to the naked eye, having an apparent visual magnitude of +5.25.[2] According to the Bortle scale, that means it can be viewed from dark suburban skies.

This is a B-type main sequence star with a stellar classification of B9.5 V;[3] just shy of being a cooler A-type star. It is estimated to have 2.6 times the Sun's mass and 3.25 times the radius of the Sun. It is 146[8] million years old, with a projected rotational velocity of 152[7] km/s. The star radiates 100 times the solar luminosity from its outer atmosphere at an effective temperature of 10,139 K.[6]
