Krypton was the home planet of Kara Zor-El and Kal-El 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]

War with Daxam

Krypton is known to have feuded with her 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]


When the planet was in chaos, Kal-El was sent to Earth along with his cousin, Kara Zor-El, to look after him. Shortly following their departure, the planet exploded, destroying it and sending radioactive pieces of the mineral, Kryptonite, flying into space, particularly to Earth.[3]
