The most common, smallest, and coolest type of true star in the universe. ({{w|Brown dwarf|Brown dwarfs}} are smaller and cooler, but do not undergo hydrogen fusion.) These can live for trillions of years; the first red dwarfs to form in the universe are still alive today and will be alive long after the Sun reaches its end. |
''{{w|Red Dwarf}}'' is also a science fiction TV series being produced in UK since 1988, named after the eponymous mining ship. This ship is ''small'' (compared to a star) and {{w|Cat_(Red_Dwarf)|one of the characters}} is indeed very ''cool'' (as in a cool cat), but ''dim''-witted (the star of the series is none too bright, either). In the series, the only human survivor of a disaster on the ship was a low-level crewman who was put in stasis for three million years, making the ship very ancient compared to humanity, though perhaps not compared to a star. | ''{{w|Red Dwarf}}'' is also a science fiction TV series being produced in UK since 1988, named after the eponymous mining ship.
