Particle Field not emitting at all

I created a particle field sphere and am trying to use it to simulate stars in my game. I have the following setup but when I try to simulate it no particles are generated. Any ideas?

Your sphere radius, 10,000 units, is farther than the “far clipping plane” of your main camera which is defaulted to 1,000 units. You either increase your camera clipping plane or reduce your particle emitter radius. But even so, the start size of your star particles is still too small for this distance from the camera.
