Location

Krypton was located close to Earth, at least in cosmic terms. It was 50 light years from Earth and orbited a red giant star known as Rao. Krypton is roughly Earth sized and was part of Green Lantern sector 2813 (Earth is in sector 2814). However, in the story "Superman: Birthright", Krypton was said to be in another galaxy, approximately 2.2 million light-years away. Krypton is home to a race of people known as Kryptonians that are similiar to humans but are more closely related to Daxamites. Under their Red Sun the Kryptonians became more technologicaly advanced society.

People and Culture

Krypton was a world renowned for it's scientific achievement. As a culture the people lead an idyllic life surrounded by robots and followed a ritual path through life. One of their achievements were their Clone Banks. Their mastery of cloning allowed them to live an eternal youth and their society grew ever more hedonistic. In these banks each Kryptonian would maintain three mindless Clones which could be used as spare parts if their "owner" was ever injured. Their was growing concern however, that the clones too had rights. At first what started out to be a pacifist movement ended up being The Clone Rights Movement that began with the teachings of Sem-M. One clone gained independant sentience, causing the debate to escalate into conflict. Eventually the Clone Rights Movement formed such a large force that they rebelled against the ruling authority. The advanced scientific knowledge of the Kryptonians was turned into super weapons and Krypton's Clone War began. Two weapons were created at this time, the Eradicator and the Destroyer. The Eradicator had altered the genes of Kryptonians so that they could never leave their planet again. The Destroyer was aimed at the planet's core, by pro-clone forces causing a chain reaction. The Destroyer was stopped when the government ended hostilities and the planet was saved.

Krypton would never be the same. The world was left with no wildlife and the people began living in isolation from one another and other races. Direct physical contact became prohibited and procreation was fascilitated by birthing matrices. Krypton had peace again, but their world was sterile and joyless.

Daxamites

The people of Daxam originated on Krypton. They left to explore the universe, though they were altered by the Eradicator as they left, leaving them fatally vulnerable to lead.

Global Catastrophe

The planet's core became increasingly unstable, due to the reactions the Destroyer had caused and began emmitting deadly radiation. The scientist, Jor-El discovered that the planet would soon explode. Jor-El was unable to convince his associates of the impending danger, who could not conceive of leaving Krypton and was himself prevented from leaving. However, he sent his child's birthing matrix to safety shortly before the planet exploded.

Notable Residents

Krypton is most famous for being the birthplace of Kal-El, better known as Superman. It was also home to his parents, Jor-El and Lara and his cousin, Kara Zor-El (Supergirl). It was also the birthplace of General Zod(General Dru-Zod) and his allies Ursa and Non. The monster, Doomsday, was also created there by a scientist known as Betron. Betron is known for teaching Kryptonians the science of genetic engineering who was later killed by his creation Doomsday.

Other versions of Krypton

Krypton of Earth-One

Silver-Age[Earth-One]Krypton

The Silver Age Krypton happened between the 50's  and 70's. Many people looking to add something new to Krypton, trying to find different ways about the dead planets origin as their inspiration , began to realize that for a planet that exploded had a lot of survivors. So in Superman: The Movie this allowed designer John Barry who also did Star Wars and Clockwork Orange to create Krypton into a crystalline utopia. This version of Krypton featured a highly advanced society,where this planet is crime-free.Criminal will be banished into outer-space until the criminal's crime intention was completely erased and he/she will be put to use again after his/her sentences is over.This kind of sentences was completely ignored after Jor-El discovered the Phantom Zone.This Planet Krypton was destroyed due to Krypton's unstable uranium core explodes.

Jor-El knew that the council of science was not considering to take action even to the very last moment when their red sun threatens to consumed their world,he put Kal-El in his prototype machine,where the machine transmitted Kal-El's atoms across the galaxy,and Kal-El was safely rematerialized on Earth.Moments after that,a large radioactive solar flare that was generated by Krypton's red sun completely consumed the entire planet.Everyone there died instantly.
