The Moon was first imaged by Kal-El's ancient ancestor Sul-El. While seeing markings on both moons, he found Wegthor's markings hazy and surmised that it may have an atmosphere. It proved suitable enough for a lunar colony.
The moon and its 500 colonists were accidentally destroyed when Kryptonian scientist Jax-Ur tested a nuclear missile designed to destroy a meteor. As a result Jax-Ur was the first Kryptonian imprisoned in the Phantom Zone.
After its destruction, Wegthor's debris formed rings around Krypton.
