Arcturus

 

Arcturus is a planetary system orbiting a orange K-class star.  The system lies in the Bootes Constellation of the Inner/Sol Region.

 
Arcturus is a red giant with a mass similar to Sol's, Arcturus can be viewed as an advanced version of Sol.  Arcturus's primary planet was the one of the earliest settlements outside Earth by the Terrans.  Waves of colony ships travelled to Arcturus looking to build a large-scale, permanent population.

 

Arcturus's primary planet Nubu is a habitable world, Nabu experienced swift growth shortly after the start of Interstellar Colonization by the Terrans.  Colonists were drawn to Arcturus by the plant life and pleasant enviroment on Nabu.  Plant life is extensive and luxuriant, Nabu's surface is covered in dense trees and ferns.
