}}{{starbox end}}Epsilon Sextantis (ε Sex, ε Sextantis) is a solitary[18] star in the equatorial constellation Sextans. With an apparent visual magnitude of 5.24,[3] it is faintly visible to the naked eye on a dark night. The distance to this star, based upon an annual parallax shift of 16.86 mas,[ is about 193 light years.]
This is an F-type subgiant star with a stellar classification of F0 IV.[4] However, Malaroda (1975) gave a classification of F2 III,[22] which would indicate a more evolved giant star. It is estimated to have nearly double the mass of the Sun.[11] The star is around 1.1 billion years old and has a projected rotational velocity of 63.5 km/s.[10]
