How did the constellation Leo get its name?

Answer 1

The Chaldeans associated Leo with the sun since it is in the sky during the summer solstice (although this is no longer true, due to the precession of the Earth's axis). Since the Nile floods around this time, the ancient Egyptians worshiped the celestial lion.

You can find Leo in the sky by looking for the "sickle" starting at Regulus (Alpha Leonis), the brightest star in the constellation, and following the backwards question mark.

Another opinion suggests that Leo was a great Lion in the time of Hercules. It is said that Hercules fought this great beast as a task for one of this twelve labors.
The Greek and Latin word for Lion is Leo. The greeks considered the Lion toi be the king of all beasts and thus named the oldest constellation known in astronomy Leo in honor of the animal.
Leo is lion in Latin.

Answer 2

The constellation Leo got its name from the Latin word for lion. It is named after the Nemean Lion from Greek mythology, a creature slain by the hero Hercules as one of his twelve labors. The star pattern in the sky was thought to resemble a lion, hence the name.
