When returning home from a mission in space, Green Lantern came across a living planet that named itself Green Lantern and shaped a continent to resemble him in honor of the hero. Learning that the planet was alive, Green Lantern used his power ring to save it from a pressure build up in it's core. The flaming material that was part of this pressure build up was expunged and shot into space where it became the planets own sun.
- Planet Green Lantern should not be confused with Mogo the living planet that is part of the Green Lantern Corps.
