Red dwarf

A Red dwarf is a type of star that is smaller and cooler than our sun. Link to artist’s impression of a Red dwarf star. The majority of stars are Red dwarves though relatively few are known. Red dwarf stars are relatively cool and faint. Astronomers can only pick them up within a hundred Light years or so of the Solar System. Proxima Centauri is the nearest star to the Solar System and is also a Red dwarf.
