Tau Ceti system

Tau Ceti (τ Cet / τ Ceti, pronounced /ˌtaʊ ˈsiːtaɪ/) is a star in the constellation Cetus that is similar to Sol in mass and spectral type. At just under 11.9 light years distant from the Sol system, it is a relatively close star. Like Sol, Tau Ceti is a yellow-orange dwarf star. An Oort cloud was located at the edges of the system.

This system was inhabited by a significant Covenant presence in 2552, including a massive fleet of warships prepared to attack Earth and the refit and repair station Unyielding Hierophant. The station was destroyed by UNSC forces September 13, 2552, including the majority of the Covenant fleet.

Trivia
Tau Ceti is also the setting for the first Marathon game.
