A red dwarf is a small star that burns fuel slowly and lives for a very long time.

Why red dwarfs last so long

Red dwarfs use their fuel slowly. Because they are small, they do not burn through energy as fast as larger stars.

Why they matter so much

They are among the most common stars in the Milky Way, so they are important when readers learn how stars are spread through our galaxy.

How they compare with the Sun

A red dwarf is dimmer, smaller, and cooler than the Sun, but it can remain stable for far longer.

How to picture it

Imagine a steady red-orange lamp in space: not powerful like a giant star, but patient and long-lived.
