Gamma Andromeda
Gamma Andromeda is a star system in which a nuclear meltdown occurred in 50 F.E, in Foundation by Isaac Asimov. The meltdown killed several million people and destroyed at least half the planet. It was caused by ill-done repairs and shoddy-made replacement parts done several decades before. Following the incident on Gamma Andromeda V, the Galactic Empire considered severely limiting the use of nuclear power. Given that the real star Gamma Andromedae, or Almach, is 350 light years from Earth, Asimov may have had this name in mind when writing this line.
