Arcturus is a star of Spectral Class K1.5 IIIFe also known as a Orange giant,
and is 37.5 light years distant from Sol. It was one of the systems first colonised under the First Diaspora between 2118 and 2148. It is not known whether the colony continues to be known simply as Arcturus, or whether the system is now known by the name of its capital world - as is the case with Vekta, Helghan and Gyre.
An ISA Cruiser is named after the star system Arcturus.
