Microstar

A microstar is a rare, extremely small type of star.

History and specifics
In 2269, the USS Enterprise (NCC-1701) discovered an artificial blue microstar in orbit of the rogue planetoid Anomaly. The microstar contained a pea-sized black hole. This quantum singularity had a mass of hydrogen and helium surrounding it, and the energy released when these particles fell into the event horizon created illumination and warmth for the planetoid. However, the quantity of particles could only last for a decade, and the black hole was also too massive for its size. The microstar's hydrogen and helium were continually refueled, and the extreme gravitational fields were being held in check, by the indigenous Arivne through psychokinesis.
