"Discovered in the late 1960's, this binary star-system is located in the Reticulum [Rhomboidalis] constellation, which is seen from Earth's Southern hemisphere." (PoL)
Zeta Reticulum lies approx. 37 LY away from Earth.
Its inhabitants are called the Zetas, and they are supposed to be largely responsible for the abduction phenomenon. For more information on the Zetas, see: Zetas.
From November 2005 onwards, information was leaked on the Internet about a planet, called Serpo, in the Zeta Reticulum system. In the documentation, its inhabitants are refered to as EBEN. See 'Serpo' for more information.
