Forum:KB:Night on Coruscant

I just watched a science video and it said, due to the black hole in the center of a galaxy, stars are group pretty densely near the core, which cause the bright center in the galaxy. Coruscant is located pretty close (in galaxy term) to the core, that means that stars are probably very close together there, then how do coruscant actually get nighttime? Shouldn't it stay bright all the time? (I mean without the city lights, of course)
