Zeta Reticuli is a pair of G class (sunlike) stars deep in the southern sky, about 39 light-years from Earth. No planets have been confirmed to exist around either of these stars, but Zeta2 appears to have its own Kuiper belt. The first Alien film is set in this system as well as its prequel, Prometheus.
It has gained a strange sort of fame as the home of the aliens who visit Earth to abduct humans. The evidence for this is a star map drawn from memory by Betty Hill, who claimed to have been kidnapped by aliens in 1961. Despite the dubiousness of this source, the idea has hung around in ufology for over 50 years, with folks like Bob Lazar claiming Zeta Reticulans are in cahoots with the US government.
