Joozey, I know exactly what you mean, I had the same problem back then.
One way that springs to mind is: - Download a rock-image like this one: http://cgtextures.com/login.php?&tex...bg7ra0eg1m1flg6 - Duplicate the layer - Blur and increase contrast on one of the layers and then use it as a "layer mask" for the other layer
That doesn't give you a perfect planet texture, but I think it's a pretty good start. Result (I also played with the "curves" tool before setting the image as a layer mask):
