Hydra
Hydra is the largest constellation in the night sky measuring 104 arc minutes in length and takes up 1,303 square degrees in area. This constellation is dotted with numerous galaxies, nebulae and star clusters.
Few bright stars brighter than magnitude 2.16 populate Hydra. The star Alphard translates from the Arabic meaning “the solitary one”. It is located 177 light-years from us and is pale orange in colour. If Alphard replaced our Sun, the star’s edge would reach halfway to the planet Mercury. Alphard is some 40 times larger than the Sun.
