Tatooine

Tatooine is a desert planet with almost no significance to anything apart from the fact that everyone seems to live there. You name it: Han Solo, Luke Skywalker, Obi-Wan Kenobi, Darth Vader, Jawas, everyone.

Its also where Luke found out he was a Jedi, and it is believed that Rarth Devan may have visited there at some point. Tatooine, despite being a desert planet, developed a forest for the Jawas to live in that produces Jawa Juice. Quite how, we do not know.
