Some facts along with some speculative conspiracy theory info on the wide-binary system:

-- The two stars, Zeta 1 and Zeta 2, are located in the southern constellation of Reticulum and are thus never visible to most of the northern hemisphere on Earth.

-- It's distance is around 39.4 to 39.5 light-years from our sun.

-- Zeta 1 was one of the first stars ever to be used as a solar analog by
astronomers. Zeta 1 Reticuli is separated from Zeta 2 Reticuli by at least 350 billion miles, or about 100 times the Sun-Pluto distance.

-- Zeta 2 is classed as G-1 with a luminosity of 0.9 (the Sun being l.0). This means that both Zeta 1 and Zeta 2 are very Sun-like and could well possess
solar systems much like our own.

-- Zeta2 has around 99 to 111 percent of our sun's mass, and 94 to 99 percent of its diameter. The star may be 38 to 126 percent as enriched as our sun with elements heavier than hydrogen based on its abundance of iron.

-- Currently there is no observational evidence of planets in the system, but the Anglo Australian Planet Search is looking for worlds in their classfication system under HD20807.

-- Zeta 2 has an approximate age between eight billion years, about one to three billion years older than our Sun and suggests that any
life on planets associated with them could be much further along in its
evolutionary process than we are.

-- On September 20, 1996, astronomers at the European Southern Observatory announced that they had detected possible indications of a giant planet around Zeta2 with around 27 percent of Jupiter's mass, moving in a close inner orbit (0.14 AUs) with a period of 18.9 days. Within two days, however, the discovery announcement was retracted because the detected radial velocity variations could be attributed to the aging star's pulsations (more). In
any case, the orbit of an Earth-like planet (with liquid water) around Zeta2
would have to be centered at around one AU -- the orbital distance Earth in the
Solar System -- with an orbital period of just over a year.

-- Based on the controversial
analysis of a map that was viewed by a couple of Humans and later recalled
under hypnosis, some UFO conspiracy
theorists on Earth believe that Zeta2, the brighter component, harbors the base
of space-travelling beings
(whom they call Greys").
Apparently, these Greys have been visiting Earth to abduct humans for research
and other nefarious purposes. One of their vehicles purportedly crash landed in Roswell, New
Mexico, which the U.S. Government is alleged to have been trying to cover
up. (On April 1, 1997, PBS aired a NOVA television show called "Kidnapped by UFOs?" in the
United States, which included the Hill incident -- see transcript.)
