A black hole and neutron star form the core of this system. Orbiting these and of special interest is a second neutron star, ringed, whose massive cerulean blue outer ring has a radius of just over 2.9 million kilometers. This ringed neutron star is itself orbited by a class M star. It is tempting and possible to map the neutron star's rings to better mine their bounty; however, one must approach perilously close to the neutron star's exclusion zone in order to do so. This system was discovered during the 3306 Distant Screws expedition to Colonia and Sagittarius A*.
