This page brings together all 4 constellations whose names start with the letter H, running alphabetically from “Hercules” to “Hydrus.” These star patterns stretch across both the northern and southern skies, and each one carries its own myths, history, and bright stars. Stargazers use them to find their way across the night sky, to track the seasons, and to enjoy memorable sights like clusters and distinctive stars.

Constellations are patterns of stars that people have grouped together and named, often after animals, heroes, or everyday objects. Astronomers now recognize 88 official constellations that divide the entire sky into clear regions. Many of the names we use today, like Hercules, come straight from ancient Greek and Roman stories about gods and legendary figures.
