* Constellations are patterns: They're groups of stars that we on Earth see as forming shapes. The stars themselves are at vastly different distances from us.
* Many stars make up constellations: Leo, like most constellations, has dozens, even hundreds, of stars that are part of it.
Here are some of the most notable stars in Leo:
* Regulus: The brightest star in Leo, it's a blue-white star marking the heart of the lion.
* Denebola: A blue-white star marking the lion's tail.
* Algieba: A double star (two stars close together) marking the lion's mane.
* Zosma: A bright star forming part of the lion's hindquarters.
