Epsilon Reticuli (in the literature, HD 27442) is a binary system approximately 59 light-years away in the constellation of Reticulum. The primary star is an orange subgiant star, while the secondary star is a white dwarf star. The primary star should be easily visible without optical aid under dark skies in southern hemisphere. As of 2000, an extrasolar planet has been confirmed to be orbiting the primary star in the system.
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.
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.
On December 11 2000, a team of astronomers announced the discovery of a planet Epsilon Reticuli b. With a minimum mass of 1.17 that of Jupiter and a similar radius, the planet moves around Epsilon Reticuli with an average separation of 1.16 AUs. The eccentricity of the planet is extremely low (at 0.06), and orbits around the star every 418 days (or 1.13 years).
There could be an Earth sized planet in its Trojan field.
