Krypton was the home planet of Kara Zor-El, Kal-El and the Kryptonians before its destruction. It was located 2,000 light years from Earth, orbiting an old red dwarf star called Rao.


The planet was separated into guilds, two known ones being the science and military.[1] Krypton was ruled by the Ruling Council, but it's exact composition and functioning is unknown. A major city on Krypton was Argo City which was also the hometown of the House of El. Apparently, birds didn't exist on Krypton. A flower native to Krypton was the Dar-Essa.


War with Daxam

Krypton is known to have feuded with it's sister planet Daxam over various things such as Democracy vs. Monarchy and how life should be lived. Both Krypton and Daxam went to war over their respective ideals, with casualties in the thousands.[2]


In 1979, the planet was known to be unstable, and would soon be destroyed. Amidst the chaos caused by the impending death of the world, members of the House of El chose to save who they could by sending them away from the planet. The infant Kal-El was sent to Earth, and his cousin, Kara Zor-El, was sent along with him, and instructed to look after him. Shortly following their departure, the planet finally destabilized and exploded, destroying it utterly. The destruction of the planet knocked Kara's pod off course, and also sent radioactive pieces of the mineral Kryptonite flying into space, some of which found its way to Earth.[3]

It is later discovered thath Argo City survived the planet's destruction thanks to the efforts of Zor-El.
