L2 Lagrange Point These points are located ~1.5 million kilometers outward from a planet, where the gravity from the planet and the local star are equal. This point has a semi-stable orbit, requiring only minimal course correction to maintain position. This is where [[Transit Rings]] are located near habitable planets. They stay in permanent shadow to assist with radiative cooling for their [[Fusion Reactor|fusion reactors]]. Diagram of Lagrange Points around a pair of masses.
