Flashback Friday: Krypton's Name

Each Friday, I take one of the entries from my old Super Posts and expand it into its own featured article.

This week: Krypton's Name!

Krypton first appeared as a nameless "distant planet" in Action Comics #1 (April 1938)...

...but was given a name in the first Superman daily strip, "The Superman is Born" (part 1 of Episode 1:"Superman Comes to Earth", January 1939).

It later appeared in the retelling of Superman's origin in Superman #1 (April 1939).

And, of course, it's been a part of Superman's origin ever since...with one exception that I know of. Superman: Red Son (spoiler alert) has Superman hail from a far future Earth. Of course, it also makes Kal-L a distant, distant descendant of Lex Luthor, so it's kind of just doing it's own thing. Every other version of his origin, from comics retellings to adaptations, has him come from Krypton.
