18 Scorpii is located about 45.7 light-years from Sol. It lies at the northern edge of the constellation Scorpius, the Scorpion -- just off its left claw.

18 Scorpii is a yellow-orange main sequence dwarf star of spectral and luminosity type G1-5 V-Va. A little bigger and brighter than Sol, the star may have a mass similar to Sol's[1][2][3], 1.02 to 1.03 times its diameter[1][4], and 1.05 times its luminosity. It may be 105 to to 112 percent as enriched as Sol with elements heavier than hydrogen ("metallicity"), based on its abundance of iron[3][5].

An Earth-type planet could have liquid water in a stable orbit centered around 1.02 AU from 18 Scorpii -- around the orbital distance of Earth in the Solar System. Such a planet would have an orbital period of around one Earth year.
