They are either much brighter than the Sun, or much fainter. WebRed dwarf stars are the most common kind of stars in the universe. They have such a low mass that they’re much cooler than stars like our Sun, and therefore appear very faint. Red stars are able to keep the hydrogen fuel mixing into their core, and so they can conserve their fuel for much longer than other stars.
