The Planet Krypton was an M-Class planet located in the Xeno Galaxy in the Constellation Corvus. Krypton was the fourth out of seven planets in orbit around the red supergiant Rao. The planet was home to a Type II sentient species of humanoids known as the Kryptonians who maintained a stable climate in the harsh planet via artificial means through harnessing the power of Krypton's immense sun.
