Its story

It is the brightest star in Hydrus and, at just 24 light-years away, one of the closest aged twins of the Sun ever found. A G-type subgiant that has already exhausted the hydrogen in its core and begun to swell, astronomers study it as a preview of the fate awaiting our own star several billion years from now. Around 150 BC it lay only two degrees from the south celestial pole and served as a southern reference for early navigators.
