Binary systemWhat is HYG 119548
It isn't one star, it's two. This A-class white in Aquarius forms a binary system, two bodies bound by mutual gravity, dancing around their common centre of mass. Its light reaches us from one hundred and fifty-five light-years away, having left the star around 1870, when the Suez Canal was being inaugurated at Port Said. The naked eye sees a single dot; only the telescope or the spectrum reveals the pair.
Where it is and when to see it
HYG 119548 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: the Sun sits at the opposite point of the sky and the star culminates around midnight.
