Class K Star

Basic Information

• Main Sequence K V Stars are good candidates to be the homeworld of aliens, as they are only a little colder than our sun, but have a much longer expected stellar lifespan.
  • And since Class K stars are so common (1 in 8), one would expect a universe teaming with life. See Loads and Loads of Races and Fermi's Paradox.
