Hydrus is a small constellation located in the southern sky that was created in the late 1500s based on observations made during voyages to the Southern Hemisphere. It was first recorded on a celestial globe in 1597-1598 and later appeared in star atlases, becoming an officially recognized part of the night sky that astronomers still use today for navigation and study.
