18 Scorpii [SEP] constellation
18 Scorpii
18 Scorpii is a solitary star located at a distance of some from Earth at the northern edge of the Scorpius constellation. It has an apparent visual magnitude of 5.5, which is bright enough to be seen with the naked eye outside of urban areas.
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, and Porto de Mello & da Silva (1997)
light years away in the constellation of Draco, lying about halfway between Polaris and Dubhe on the celestial sphere. Astronomers have looked for planets in the system, so far without finding any. These observations suggest that the star does not have any hot Jupiters.
