18 Scorpii is a solitary star located at a distance of some 46.1 light-years (14.13 parsecs) from the Sun at the northern edge of the Scorpius constellation. It has an apparent visual magnitude of 5.5,[2] which is bright enough to be seen with the naked eye outside of urban areas. The star is drifting further away with a radial velocity of +11.6.[2]
18 Scorpii has some physical properties in common with the Sun, a G-type star. Cayrel de Strobel (1996) included it in her review of the stars most similar to the Sun,[10] and Porto de Mello & da Silva (1997) identified it as a younger solar twin.[11][12] Some scientists therefore believe the prospects for life in its vicinity are good.
