Denebola is the tip of Leo's tail. Its luminosity varies slightly over a time period of a few hours. The star has a high rate of rotation that causes it to have an equatorial bulge.

There are a few stories that are said to contain Leo the lion. The first is the story of Hercules. A lion (Leo) was terrorizing a town and eating people and sheep. Hercules was told to kill it, but the lion's flesh was unable to be punctured by stone or metal. Hercules proceded to strangle the lion to death and skin it with one of its own claws. A second story is the story of Thisbe and Pyramus. These two lovers planned to meet at a certain tree, but Thisbe was startled by a lion that had just made a kill and dropped her veil, which the lion caught. Pyramus saw the bloody cloth and believed his love to be dead. Then he killed himself, and she took the sword from his dead body and killed herself too. Zeus placed her veil in the sky (Coma Berenices), which is located near the constellation Leo.
