Yavin to Yavin 4

The page "Yavin" is showing the planet Yavin's moon Yavin 4. (The base for the Rebel Alliance, later Luke's Jedi temple)

So just add a 4 to the page and change the blurb's word planet to moon I guess.

done

I don't want to be picky, but isn't it officially Yavin IV or can it be both?

Yeah it's Yavin IV.  The planet itself is called Yavin Prime, I believe...which I know has been mentioned in a lot of the Star Wars EU books but I'm not sure about games. 

Ha.  It is now IV.
