<P> Hydra is the largest of the 88 modern constellations , measuring 1303 square degrees . Also one of the longest at over 100 degrees , its southern end abuts Libra and Centaurus and its northern end borders Cancer . It has a long history , having been included among the 48 constellations listed by the 2nd century astronomer Ptolemy . It is commonly represented as a water snake . It should not be confused with the similarly named constellation of Hydrus . </P>
