EPSILON RETICULI

Our inner solar system superimposed behind the orbits of the planets HD 179949 b, HD 164427 b, Epsilon Reticuli Ab, and Mu Arae b (each planet has its parent star labeled next to it -- all parent stars are in the center)

'Epsilon Reticuli' (ε Ret / ε Reticuli) is a 4th magnitude star in the constellation Reticulum. The system is a binary, the primary component being an orange subgiant, and the secondary is a white dwarf. The primary star should be easily visible without optical aid under dark skies in southern hemisphere.
The primary star is known to have an extrasolar planet orbiting it.

Epsilon Reticuli A


The primary star, 'Epsilon Reticuli A', is an orange subgiant 20% more massive than our Sun. Being a subgiant it is ceasing or has already ceased fusing hydrogen in its core. Soon the star will swell up and become a red giant. Despite its advanced stage, it cannot be much older than the Sun.


ε Reticuli B


The companion star, 'Epsilon Reticuli B' is a white dwarf star located around 240 AU from Epsilon Reticuli A. It has a surface temperature between 9000 and 17000 K.
