Create a planet, kill the sun object (or save it for later - your choice), download a good picture of the moon from Google Images (free) and use this object to map (using the Image Shader) to your new planet that you have set in the distance on the horizon away from your first planet. If you have kept the sun object, make it invisible, set it at the correct angle, and then set the strength accordingly.
Or you could increase the luminosity of that planet and/or just use source lights to light it and your surrounding scenery.
These are ideas I've tried and used successfully. Try some of these and see what you come up with.
The most difficult thing might be to find a moon JPG on Google that doesn't need a lot of trimming, but it is possible.
