* The Sickle: This asterism (a recognizable pattern of stars) is shaped like a backwards question mark and forms the lion's head and mane. It contains the stars Regulus, Algieba, and Denebola.
* The Triangle: This group of stars forms the lion's rear and includes the bright star Denebola.
* The "Sickle Stars": This includes the stars that make up the Sickle asterism, which are important for identifying Leo in the night sky.
Beyond these prominent groups, Leo also contains many other interesting stars, including:
* Regulus: The brightest star in Leo and one of the brightest stars in the entire night sky.
* Algieba: A double star, meaning it appears as two separate stars when viewed through a telescope.
* Denebola: The third brightest star in Leo.
There are many more star groups and individual stars within Leo, but these are some of the most recognizable and noteworthy.
