Constellation names, like the names of stars, come from a variety of sources and each has a different story and meaning to it.
Old constellations’ names usually come from Greek mythology, while the constellations created more recently were mostly named after scientific instruments and exotic animals. However, there are no strict rules because the stories of the constellations differ from one constellation to the next.
Constellation names that come from Greek mythology or refer to figures from Greek and Roman myths, as zodiac constellations do, are probably the ones that are best known. They were created and documented by the Greek astronomer Ptolemy in the 2nd century A.D.
Constellation names associated with figures from mythology include most of the members of the Perseus family (Perseus, Andromeda, Cassiopeia, Cetus, Cepheus, Pegasus, and Auriga), the Hercules family (Hercules, Sagitta, Aquila, Lyra, Cygnus, Hydra, Crater, Corvus, Ophiuchus, Serpens, Centaurus, Lupus, Corona Australis, and Ara), the Orion family (Orion, Canis Major, Canis Minor, Lepus, Monoceros), the Zodiac family (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, Pisces), and the Ursa Major family (Ursa Major, Ursa Minor, Draco, Canes Venatici, Boötes, and Corona Borealis).
The constellations that carry names of exotic animals were for the most part introduced by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman in the 16th century, and mainly include members of the Johann Bayer family: Dorado, Grus, Tucana, Chamaeleon and Volans among others.
Below is the list of constellations with their names, genitive forms, English names, name meanings, mythical associations, and stories about how they were named.

In another myth, Boötes represents Arcas, the son of Zeus and Callisto. In the myth, Callisto’s father King Lycaon decides to test Zeus to see if the god is really who he says he is and serves him his son Arcas for dinner. Seeing what Lycaon has done, Zeus kills the king’s sons and turns Lycaon into a wolf, then collects the parts of his own son and makes him whole again. Arcas’ mother Callisto, in the meantime, gets turned into a bear, either by Zeus to disguise her and protect her from Hera’s revenge, or by the jealous Hera herself. When Arcas grows up, he comes face to face with his mother in the woods and does not recognize her. He starts to chase the bear and Zeus intervenes to prevent bloodshed and turns them into the constellations Ursa Major (Callisto) and Boötes (Arcas).
Boötes constellation is also sometimes associated with another mythical figure: Icarius, the wine maker.

It is said that the jewels turned into stars which now form the constellation Corona Borealis.

After a while, Coronis loses interest in the god and falls in love with a human man. When the bird reports the affair to Apollo, the god becomes so angry that the raven did not stop the affair that he curses it, scorching the raven’s feathers and turning them black. (The bird had originally had white feathers.) Coronis’ son, the healer Asclepius, is represented by Ophiuchus constellation.
