# Krypton (comics)
**Krypton** is the fictional home planet of Superman in [DC Comics](https://www.edgepedia.org/dc-comics), a scientifically advanced world orbiting the red dwarf star Rao that explodes and destroys its civilization, leaving the infant Kal-El as one of its few survivors sent to Earth[1](https://dc.fandom.com/wiki/Krypton). Introduced in Superman's very first appearance, it grew from a single unnamed origin panel into one of the most detailed settings in superhero comics, complete with its own history, cities, and language[2](https://www.dc.com/blog/2023/04/18/the-evolution-of-superman-s-origin) • [3](https://www.dc.com/blog/2025/07/01/krypton-unclassified-everything-you-need-to-know-about-superman-s-homeworld).

## Origins in the comics
Superman's 1938 debut in [Action Comics](https://www.edgepedia.org/action-comics) #1 devotes a single page to his origin, in which readers see a panel of Krypton during its final moments, though the planet is not named there[2](https://www.dc.com/blog/2023/04/18/the-evolution-of-superman-s-origin). The hero's home planet is mentioned from that first issue as the "devastated planet" Kal-El comes from, created by [Jerry Siegel](https://www.edgepedia.org/jerry-siegel) and [Joe Shuster](https://www.edgepedia.org/joe-shuster)[5](https://www.superman-boutique.com/en-us/blogs/actualites/planete-d-origine-de-superman-tout-savoir-sur-krypton).
**Early revisions.** The first versions of the origin stated that everyone on Krypton had the same powers Superman had on Earth. As Superman's powers grew, this raised an obvious question: why couldn't the citizens of Krypton simply use their powers to escape the planetary apocalypse? The explanation arrived in 1944's More Fun Comics #101, which established that Kryptonians lacked abilities on their home planet yet would develop tremendous ones on Earth because of its distinctive gravity.[3](https://www.dc.com/blog/2025/07/01/krypton-unclassified-everything-you-need-to-know-about-superman-s-homeworld)
The planet itself was fleshed out gradually. In the 1960s Krypton became a much bigger part of Superman's ongoing series, and over the following two and a half decades the planet was developed in extensive detail, with science as its guiding force[6](https://www.gamespot.com/gallery/krypton-the-15-most-important-versions-of-superman/2900-1921/).
## The planet and its people
Krypton is depicted as a planet populated by a race of super-strong, scientifically advanced humanoids who resemble Homo sapiens in outward appearance[1](https://dc.fandom.com/wiki/Krypton). Its primordial era produced some of the most dangerous organisms in the universe[1](https://dc.fandom.com/wiki/Krypton). Krypton's documented past features internal strife: during the [Kryptonian](https://www.edgepedia.org/kryptonian) year 9846, the military leadership of Erkol mounted an assault on Kandor, the planet's capital[1](https://dc.fandom.com/wiki/Krypton).
Kryptonian culture has been revised with each major continuity change. John Byrne's Post-Crisis reimagining of Superman's origin gave the planet a new history, and the planet's story has also been retold in dedicated miniseries: a 1987 series called The World of Krypton, not to be confused with a 1980 series of the same name, detailed the planet's Post-Crisis history, and in 2022 DC published another miniseries titled World of Krypton[3](https://www.dc.com/blog/2025/07/01/krypton-unclassified-everything-you-need-to-know-about-superman-s-homeworld).
## The destruction of Krypton
For many readers, the beginning and end of their knowledge of Superman's home planet is its destruction[7](https://www.dc.com/blog/2018/04/10/krypton-supermans-high-stakes-history). The cause has changed with each retelling. The 1978 Superman movie depicts Krypton's red sun going supernova, causing the planet to explode, while 1986's The Man of Steel #1 stated that the destruction occurred because of growing radiation within the planet core[3](https://www.dc.com/blog/2025/07/01/krypton-unclassified-everything-you-need-to-know-about-superman-s-homeworld).
In every version, the destruction sets the central story in motion: a child is rocketed to Earth just before the planet dies and is raised by a farming couple, [Jonathan and Martha Kent](https://www.edgepedia.org/jonathan-and-martha-kent), becoming Superman[8](https://edelweiss-assets.abovethetreeline.com/DCCO/pdfs/DCE%20Essential%20Graphic%20Novels%20and%20Chronology%20in%20spreads.pdf). The event also generates the mythology around it, including [Kryptonite](https://www.edgepedia.org/kryptonite), a mineral from the native planet that can weaken Superman[9](https://files.eric.ed.gov/fulltext/ED109699.pdf).
## Krypton across eras and media
**Silver Age and after.** Kryptonian characters and settings expanded far beyond the origin story. The dog Krypto, created by writer Otto Binder and artists Curt Swan and Sy Barry, debuted in [Adventure Comics](https://www.edgepedia.org/adventure-comics) #210 in March 1955 as a Kryptonian dog launched by Jor-El in a prototype test rocket, the same design later used to send infant Kal-El to Earth[10](https://time.com/7301596/krypto-dog-superman-history/). Krypto endured through the [Bronze Age](https://www.edgepedia.org/bronze-age) until DC's continuity was reset by [Crisis on Infinite Earths](https://www.edgepedia.org/crisis-on-infinite-earths) in the mid-1980s, after which the character returned in several different forms, including a dog from a false version of Krypton that Brainiac created as a trap in the 2001 event Return to Krypton[10](https://time.com/7301596/krypto-dog-superman-history/).
**A real address.** In 2012, DC published the back-up story "Star Light, Star Bright" in Action Comics #14, in which the astrophysicist [Neil deGrasse Tyson](https://www.edgepedia.org/neil-degrasse-tyson) helps Superman find his home planet on its final day of existence. By applying real-world science to the story, the issue tied Krypton's sun to an actual star in the sky[4](https://www.dc.com/blog/2012/11/05/dc-comics-and-neil-degrasse-tyson-put-krypton-on-the-map-with-historic-superman-story).
**Screen versions.** Adaptations have offered their own takes on the planet's end. The 2025 film Superman shows Superman's Kryptonian parents, Lara and Jor-El, cameoing via video message[11](https://www.gamesradar.com/entertainment/dc-movies/every-comic-book-character-in-superman/), and the 2026 film Supergilda depicts Krypton's destruction differently from the comics: Kara's father Zor-El contained Argo City for many years after the planet's initial destruction, allowing Kara to grow up there before being sent to Earth[12](https://www.gamesradar.com/entertainment/dc-movies/supergirl-ending-explained/).
## Recent comics centered on Krypton
Krypton remains an active setting in current publishing. In 2025, DC announced Krypto: The Last Dog of Krypton, a five-issue [DC All In](https://www.edgepedia.org/dc-all-in) series by writer Ryan North and artist Mike Norton, part of the publisher's "Summer of Superman" initiative[13](https://www.dc.com/blog/2025/02/20/dc-delivers-big-news-to-retailers-at-comics-pro-revealing-publishing-plans-for-summer-and-fall-of-2025).
**Elseworlds 2026.** DC's alternate-universe [Elseworlds](https://www.edgepedia.org/elseworlds) line announced three new Krypton-centered series for summer 2026. Supergirl: Survive, written by Ethan S. Parker and Griffin Sheridan with art and covers by Rod Reis, launches on June 3 and follows teenage Kara Zor-El and infant Kal-El launched into a hostile universe as Krypton burns around them, with [General Zod](https://www.edgepedia.org/general-zod) tightening his grip on the planet. Superman: Father of Tomorrow, written by Kenny Porter with art and covers by Danny Earls, launches on May 27 and imagines a world where Jor-El, not his newborn son, crash-lands in Kansas and becomes Earth's greatest protector. Dark Knights of Steel II continues the fantasy epic that opened with the destruction of Krypton and the planet's escape aboard a spaceship[14](https://www.dc.com/blog/2026-03-17/dc-expands-its-elseworlds-line-with-new-series-in-2026) • [15](https://as.com/meristation/comics/reportajes/los-caballeros-oscuros-de-acero-unos-batman-y-superman-alternativos-situados-en-la-edad-media-f202605-n/).
**Alternate Kryptons.** The planet also anchors alternate-reality characters. Superboy-Prime is a Kal-El sent from a doomed Krypton to an otherwise superhero-free universe, raised in New England by Jerry and Naomi Kent and named after the popular comic book character[16](https://www.dc.com/blog/2026-05-27/a-super-primer-on-superboy-prime).
## The planet's place in the mythos
The destruction of Krypton functions as the engine of Superman's story rather than a fixed plot point, and writers have used that flexibility in different directions. The cause of the catastrophe has shifted from a supernova to core radiation depending on the era[3](https://www.dc.com/blog/2025/07/01/krypton-unclassified-everything-you-need-to-know-about-superman-s-homeworld), and screen versions have added further variations, such as the Argo City survival story in the 2026 [Supergirl](https://www.edgepedia.org/supergirl) film[12](https://www.gamesradar.com/entertainment/dc-movies/supergirl-ending-explained/). The 2012 Tyson story went further by anchoring the fiction to real astronomy, changing Superman's place in history by giving his home planet a location readers could actually find in the sky[4](https://www.dc.com/blog/2012/11/05/dc-comics-and-neil-degrasse-tyson-put-krypton-on-the-map-with-historic-superman-story).
