Presuming that it takes several billion years of complex live to evolve in a stable environment, the stars most likely to currently have inhabited planets are

Question

Quizplus · Accepted Answer

G to K main sequence stars have stable environments that could support complex life for several billion years. B to A main sequence stars have shorter lifetimes and greater instability, making it less likely for complex life to evolve on their planets. G to K giants have short lifetimes and are unstable, while white dwarf stars and neutron stars are too small and/or too intense in their radiation for complex life to survive. G to K main sequence stars have a stable lifespan of several billion years, providing enough time for complex life to evolve on any orbiting planets. B to A stars have shorter lifespans and are more likely to die out before complex life can evolve, G to K giants may have habitable zones too close to the star, and white dwarfs and neutron stars are not stable enough to support life.
