DescriptionThe Male Water Snake was created by Dutch navigators Keyser and de Houtman in the 1590s to complement the ancient female Hydra of the northern skies. It occupies the far southern sky between the two Magellanic Clouds. The constellation contains HD 10180 — a remarkable star system about 127 light-years away with at least seven confirmed planets, one of the most multi-planetary systems known. The brightest star, Beta Hydri, is the closest bright star to the south celestial pole visible to the naked eye — a yellow subgiant very similar to the Sun, just 24 light-years away and one of the nearest solar analogs.
