Krypton is the home planet of Superman and Supergirl (Kara). It is located several solar systems away from Earth and on the left or about 21.7 light years. One day, Kara went to Krypton High School on her pet horse Comet. She was teased by a trio of bullies for using a horse instead of a hover board. They shoved her into a pool of mud. Kara rushed to science class and was chosen to present her project for finals first. While Kara's new solution for growing crystals three times as fast was a success, one of the bullies let Comet go. Kara dropped the solution and ran outside to get Comet. A giant crystal burst out from the roof. The science teacher flunked Kara for being so careless and neglectful. While out with Comet and Krypto, Kara discovered a Mnemosyne Crystal and showed it to Alura. She polished it and programmed it so Kara would always remember her family and home. The planet met its natural destruction and imploded. Two Kryptonians were sent away in single occupant spacecraft each, an infant Kal-El and teenage Kara Zor-El.
The destruction of Krypton was part of a prophecy recorded on Gemworld. It foretold the last gem of an extinct planet bound with treasure from across the universe would give way to ultimate power. Supergirl's Mnemosyne Crystal was used to complete Eclipso's Scepter and she plotted to destroy Gemworld and take over the universe with it.
