The monster Hydra from the second labor of Hercules is also a constellation. Eighty-eight constellations have been discovered. Andromeda, Cassiopeia, Orion, and Perseus are named after Greek heroes.
Constellations are very interesting.
An observer at the equator sees all the constellations, while an observer at the North or South Pole sees only one hemisphere of constellations. Many of the constellations are named after Greek heroes. You can see different constellations in different seasons. Though not many people use constellations for navigation anymore, they are still very interesting and can tell us many things. People are still inventing new things that are made only to study constellations.
