Zeta Doradus system

The Zeta Doradus system is a planetary system near UNSC-controlled space, approximately 38 light-years from Sol. It contains many planets orbiting the star Zeta Doradus, almost all of which are icy rocky planets or gas giants, none of which are habitable. The one exception, however, is the artificial planet known as Onyx.

The UNSC cruiser was refit to serve near Zeta Doradus in 2550. In 2552, the Battle of Onyx was fought in the system.

Trivia
Dorado is an actual constellation, and it does possess a Zeta Doradus within it.
