Lighting objects with emissive material

Hi!, I’m having some trouble with getting objects lighted from a emissive material. I’m developing a level that simulates the solar system, being the sun the emissive material but hte light does not illuminate any planet. I’ve tried a lot of things and I think it might be caused by the distance between them, about 149000000 uu, that atenuates the light intensity. Do you have any ideas?

Thank you so much for your help :).

Its late as hell, but just dont. Use a non inverse square falloff pointlight with the source radius set to the size of the sun. Why are you even attempting to bake light in this situation in the first place?
