}}{{starbox end}}HD 173791 (30 G. Telescopium) is a giant star in the constellation Telescopium, located about {{Convert|358|ly|pc|abbr=off|lk=on}} from Earth. It has an apparent magnitude of +5.8, allowing it to be viewed with the naked eye under suitable viewing conditions. The stellar classification is G8III, which indicates that it has evolved from a main sequence star and has expanded into a giant with three times the Sun's radius.[9] The effective temperature of its chromosphere is 5,200 K,[8] giving it the characteristic yellow hue of a G-type star.[15]It has an estimated lifespan of 10 billion years and has about the same mass as the Sun. After passing through the giant stage, its end state will probably be a carbon-oxygen white dwarf.[8] References1. ^1 {{citation | last=Evans | first=D.
