Stars

Stars are giant spheres of hot plasma powered by nuclear fusion. They create the heavy elements that make planets — and life — possible.

Types of Stars

• Red Dwarfs — smallest, longest-lived
• Yellow Dwarfs — like our Sun
• Red Giants — dying stars expanding
• Supergiants — massive, short-lived, explosive
• White Dwarfs — stellar remnants
