  That depends in whether you want it to look like a photo or just like
an artistic image.
  Photos of planets and other similar well-illuminated objects in space
do not usually show stars (including the ones taken in the Moon). This is
because the exposure time of the camera is set so that the planet will look
good (ie. not overexposed). Stars are usually too faint to be photographed
with such a short exposure time; photographing the stars would need a longer
exposure time, which would make the planet overexposed (almost white).

  If you ever see a photo of a well-illuminated planet also showing stars,
you can be sure that the photo is fake or at least altered (ie. the stars
have been added later).
