[10] The brighter star should be easily visible without optical aid under dark skies in the southern hemisphere.

The primary component, Epsilon Reticuli A, is a subgiant star with a stellar classification of K2III–IV, indicating that the fusing of hydrogen in its core is coming to an end and it is in the process of expanding to a red giant.

[11][12] It was noted that its color indices are incompatible with a main sequence object, but are consistent with a white dwarf.

[12] This was confirmed in 2007 by spectroscopic observations, that showed the absorption spectrum typical of a hydrogen-rich white dwarf (spectral type DA).

[14] With a minimum mass of 1.17 that of Jupiter, the planet moves around Epsilon Reticuli with an average separation of 1.16 AU.
