What you need to do is link it to a light. Create a new spot light ( you must name it “Emitter” for this to work. Place your light in z space behind the camera and set key frames. move forward in the time line and move the light forward to wherever you want it to hit. Now go into your particular settings and twirl down the emitter settings and set emitter type to light. now your comet will follow whatever path you have made with your light.
