Zeta2

Zeta2 Reticuli
A yellow-orange main sequence dwarf star of spectral and luminosity type G1-2 V, Zeta2 has about the same mass (99 percent), around the same diameter (almost 99 percent), and almost same luminosity (102 percent) as Sol.

Zeta2 Aquarii and zeta1 Aquarii form a binary of two equal white stars with an orbit of 760 years. Zeta2 Aquarii is the primary: 4.4, 4.6; current PA 266º and separation: 2.3".

Zeta2 Reticuli has a very similar mass and luminosity to our Sun. The spectral type of the star is G1 V. The star was suspected to have a close stellar companion, but it was deemed to be an instrument artifact.

35 mag (zeta2) and an A9 subgiant of 5.93 mag (zeta3). These two can easily be observed with binoculars. Small scopes reveal another companion: another A1 main sequence star of 7.21 mag (zeta1).
