 An orange star slightly smaller and less massive than the Sun, and relatively close to the Solar System, it is frequently featured in works of science fiction.It is classified as a type K2 star, with the corresponding suggestion that it has a stable habitable zone and is well suited for life.However, one factor which weakens the case for habitability is its youth—as little as 200 million years old—and consequent high levels of ultraviolet emission (see "Implied Spaces" by Walter Jon Williams, below).
