A red dwarf is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed. From Earth, not one star that fits the … See more The term "red dwarf" when used to refer to a star does not have a strict definition. One of the earliest uses of the term was in 1915, used simply to contrast "red" dwarf stars from hotter "blue" dwarf stars. It became established … See more The spectral standards for M type stars have changed slightly over the years, but settled down somewhat since the early 1990s. Part of this is … See more Many red dwarfs are orbited by exoplanets, but large Jupiter-sized planets are comparatively rare.

As a result, they have relatively low pressures, a low fusion rate, and hence, a low temperature. The energy generated is the product of nuclear fusion of hydrogen into helium by way of the proton–proton (PP) chain mechanism. … See more Modern evidence suggests that planets in red dwarf systems are extremely unlikely to be habitable.
