Leo, the Lion, is a prominent constellation in the Northern Hemisphere. While it contains many stars, some of the most notable ones are:

* Regulus: The brightest star in Leo, a blue-white star. It's also one of the four "Royal Stars" of ancient Persia.

* Denebola: The second brightest star in Leo, a white star. It marks the lion's tail.

* Algieba: A double star, visible with binoculars or small telescopes.

* Zosma: A yellow-white star that marks the lion's back.

* Chort: A white star that marks the lion's chest.

There are many other stars in Leo, forming the lion's body and mane. Some of these are fainter and harder to see with the naked eye, but they contribute to the overall shape of the constellation.
