Hydrus means the male water snake. It shares a border with the constellations Dorado, Eridanus, Horologium, Mensa, Octans, Phoenix, Reticulum and Tucana. Hydrus lies in the southern circumpolar region and is a beautiful place to buy a star package if you live in the southern hemisphere. Most of the northern hemisphere cannot see it at all.  

Despite its small size and relative faintness, Hydrus contains several interesting stars and deep-sky objects that are worth exploring.  One of the most notable stars is “Beta Hydri”, which is a yellow sub-giant star located approximately 25 light-years from Earth. Beta Hydri is the brightest star in the constellation with a 2.8 magnitude. It is the closest bright star to the celestial south pole. Another interesting star in Hydrus is “Alpha Hydri,” which is a yellow-white subgiant located approximately 72 light-years from Earth. Alpha Hydri is one of the brightest stars in the constellation and is easily visible from the southern hemisphere.
