Orono is a planetary system orbiting a orange K-class star.  The system lies in the Cetus Constellation of the Cetus Region.

The primary planet of the Orono System is a world whose surface is covered in a mixture of various ices and water.  Deep deposits of valuable minerals are located deep below the planet wide oceans


Multiple efforts have been attempted to extract the minerals, but have ultimately been unsuccessful due to the endeavors not being profitable.  The planet is home to a small population who mostly reside in orbital stations, the planet's surface is rarely visited by anything beyond exploratory teams.
