Inaccuracy is fine too instead of weakness. Could even be slightly fairer if planets fire back at super-range.
It still gives ships a chance to win, if it does splash damage. Misses against spacecraft just miss. Against planets, still chance for explosive hit.
Or make up something to prevent use by planets. Perhaps causes massive radiation in firing chamber hazardous to cities, but can be vented in space.
