Epsilon Eridani

Epsilon Eridani (ε Eri / ε Eridani) is a notable main-sequence K2 class star. It is the closest star in the constellation of Eridanus at 10.5 light years from the Solar System (around 5 days in slipspace in a human ship) and is the third closest star visible to the naked eye.

Epsilon Eridani has no official proper name (being called only by its Bayer designation), although Arab settlers along the East African coast occasionally applied the name الصادرة Al-Sadirah "the Returning Ostriches" to the star nearly seven centuries ago.

Due to it being a relatively close and sun-like star, Epsilon Eridani regularly appears in science fiction. Its closest neighbor is Luyten 726-8 (UV Ceti and BL Ceti), 5.22 ly (=1.60 pc) away.

Epsilon Eridani was home to Reach until late August and early September, when it was conquered and glassed by the Covenant.
