Whatever Happened to... the Lost Moons of Krypton?

Both Kryptons in the universes of Earths One and Two had twin moons encircling those now extinct planets. One of these moons was named Mithen, and was less notable than their famous  celestrial contemporaries. Meet Wegthor and Koron.

Wegthor was the primary moon of Krypton-One, which was colonized as a lunar colony staff with 500 colonists. These Kryptonians and their new home were destroyed by a missle, built and sent by the scientist Jax-Ur, which strayed from its intended trajectory of an astronid. Jax-Ur was banished to the Phantom Zone for this serious infraction.

Koron was its twin, which orbited Krypton-Two. When an experimental life-extending serum created by Zor-L was used on a gigantic Snagriff, which made it invulnerable and changed its metabolism. To save his world from the creature, Jor-L exiled it to Koron, which was later propelled from its parent planet when Krypton-Two exploded. The Snagriff at almost all the moon, until it entered Earth-Two's orbit when it disintegrated. Later, the Snagriff joined it when consuming several volatile atomic bombs while battling its jailer's son, Superman!
