Spock famously comes from the fictional planet Vulcan. However, the show creators originally had a different idea for his homeworld. What planet was Spock originally supposed to come from?

Spock's character evolved as the show was being developed. In the original pitch, Spock was half-Martian and was supposed to have a reddish skin tone. However, the show creator Gene Roddenberry feared that humans would land on Mars before the end of the show, rendering Spock's "alien" nature obsolete.
