This, to me, is one of the big mysterys of the 2600. None of the current emulators (including my own) handle the stars correctly. I have looked at the code and stil can't figure out how it is done. The starts are definatly missiles, but on all the emulators they appear in a straight vertical line. It must have something to do with the horizontal motion registers.
