Omicron Ceti

Omicron Ceti (also known as Mira) is the primary of the Omicron Ceti system. It is on the fringes of Federation space, about two dozen light-years coreward of Kropasar. Its emissions include deadly berthold rays, rendering its otherwise eminently suitable planet Omicron Ceti III unsuitable for colonization.
