The Lion

Leo is a Zodiac constellation in the northern celestial hemisphere. Its name is Latin for lion.

It is one of the 48 original Ptolemaic Constellations.

Leo is one of the most easily recognizable constellations due to its many bright stars and a distinctive shape that is reminiscent of the crouching lion it depicts. The lion's mane and shoulders also form an asterism known as "The Sickle."

The brightest star in the constellation is Regulus, which is Latin for "prince" or "little king." In Arabic, it is also known as Qalb al-Asad, meaning "the heart of the lion".
