Sextans (pronounced /ˈsɛkstənz/, Latin: sextant) is a minor equatorial constellation which was introduced in the 17th century by Johannes Hevelius.
Being a modern constellation, Sextans has no mythology associated with it. It was designed to represent an astronomical sextant, an instrument that Hevelius made frequent use of in his observations.
Sextans is not a particularly bright constellation. It has only one star above the fifth magnitude, namely α Sextantis at 4.49m. The constellation contains a few double stars, including γ, 35, and 40 Sextantis. There are few notable variable stars, including β, 25, 23 Sextantis, and LHS 292.
