Can you make particles orient towards/away from center of the emitter?

Look for Emitter Normals Mode in the Default Required module. Spherical or Cylindrical might work, but it probably needs to use another module, and consist of 5 emitters, each of their Emitter Normals Mode set to Spherical or Cylindrical. The other module(s) to use may be Location and Rotation, and there’s also the Orbit module. Sounds tricky.
