red dwarfs
Small cool stars
Red dwarfs are small, relatively cool stars that burn their hydrogen fuel slowly, giving them extraordinarily long lifespans—longer than the current age of the universe.
They are the most common type of star in the Milky Way, though too dim to see with the naked eye.
Astronomers searching for habitable exoplanets often focus on red dwarfs because of their abundance.
