By far the most common class of star in our galaxy and the Universe are red dwarfs. These are weak, dim stars with no more than 40% of the mass of the Sun, and the brightest of them shine at only 10% of the Sun’s luminosity. Because they burn their fuel so slowly they have lifespans much longer than our own star, of at least 10 billion years. Around 80% of all stars in our local neighbourhood are red dwarfs.
