Red Dwarf Stars

Red dwarfs are small, cool stars that are the most common type of star in our galaxy. They are much smaller and fainter than the Sun. Red dwarfs can burn for trillions of years, far longer than the Sun is expected to last.

Most stars in the Milky Way are red dwarfs, but they are too faint to see with the naked eye. Some red dwarfs have planets, and scientists look for signs of life on them.
