The Leo constellation is made up of many stars, but the most prominent ones that form its recognizable shape are:

1. Regulus (Alpha Leonis): The brightest star in Leo and one of the brightest stars in the night sky. It marks the heart of the lion.

2. Denebola (Beta Leonis): The second brightest star in Leo, located at the lion's tail.

3. Algieba (Gamma Leonis): A double star, meaning it's actually two stars orbiting each other, located at the lion's mane.

4. Zosma (Delta Leonis): Located at the lion's back.

5. Chort (Theta Leonis): Located on the lion's flank.

6. Rasalas (Epsilon Leonis): Marks the lion's mane.

7. Adhafera (Zeta Leonis): Marks the lion's head.

8. Subra (Mu Leonis): Located on the lion's front paw.

These are just the main stars that form the shape of Leo. The constellation actually contains many more stars, but these are the ones that are typically used to identify the lion's figure in the night sky.
