Krypton is the home planet of Superman.
Krypton was an idyllic world in another part of the universe, which gave birth to a race of "supermen". All Kryptonians have the same powers as Superman. The reason is because of Krypton's lower gravity that they were powerless on their own planet.
It was said to had been born over 6 billion time cycles ago from the gaseous mass flung from the red sun of the solar system. (World of Krypton v1 #1)
Around 100,000 years ago, the planet was known as Ny'l'uyl that was inhabited by a hairless race of humanoids that had become masters of the planet that were a content people who had long abandoned warfare. Their science detected a celestial object that was predicted to strike their homeworld and destroying the surface leading to the natives constructing large stasis chambers to shelter their population underground. They were to remain for 20 years whilst their ruler volunteered to stay watch over the years where he took refuge at various points to ensure his survival. For reasons unknown, the instruments did not awaken the ruler in the allotted time and instead thousands of years had passed. During this time, their world gave rise to a new civilization that were the soft skinned Kryptonians who had built their society on the surface. (Superman v1 #397)
Krypton was a super-advanced paradise where science ruled above all. Through the use of science, Kryptonians had freed themselves from all worries, cares, chores, and wars. Robots and computers were used for everything, even for determining what career paths the young children would take as they grew up.

Long ago, an onrushing meteor threatened the planet Krypton where it would strike the world in ten days and had the power to destroy whole cities. A scientist by the name of Skal-Var began construction of a rocket designed to destroy the comet before it impacted his world. However, the comet's generated an electrical disturbance that disrupted the guidance system of the rockets causing each to miss. Skal-Var would not have the time needed to create a guidance system to bypass the electrical disturbance and in desperation he built the Comet-Missile 3X which he would pilot in order to ensure it hit its target. Thus, the comet was destroyed before it could bring harm to Krypton but this came at the cost of Skal-Var's life. As a result, he became regarded as a hero on his homeworld for his sacrifice and his Comet-Missile 3X became considered one of the relics of Krypton. (Superman's Pal, Jimmy Olsen v1 #69)
As science began to mature on Krypton, nuclear disaster erupted on their world that devastated an entire town and killed thousands. In response, the government forbade scientific research leading to it being outlawed and creating a period of anti-science fanatics. This resulted in a time where Kryptonian scientific developments was stunted. (Adventure Comics v1 #333)
In its history, Kandor, the capital of Krypton, was shrunk and taken away by Brainiac. Kryptonopolis, another major city, was the new capital. Space flight was banned as a result of an experiment performed by Jax-Ur which destroyed one of Krypton's two moons.
The destruction of Krypton was the result of a build-up of internal pressures at its core. The explosion transformed of the matter which made up Krypton into a various kinds of kryptonite. Kal-El, the survivor of Krypton, was rocketed to Earth before its destruction.
Long ago, a powerful and wise race of magnetic beings called the Xan once ruled Krypton where they used their powers to bring the Xuthful ore from space onto the planetary surface with their living electromagnetic field abilities. Their civilization later collapsed with the only remains of their society being at the Proto-Tombs of Xan. (Superman: The Man of Steel v1 #111)
