as they are Rock/Psychic, i imagine they can telekinetically control asteroids and meteors in outer space, for other abilities Solrock would also launch small and massive but controlled solar flares, coronal mass ejections and prominences coated in psychic energy, Lunatone would use psionic moonlight to alter the tides of oceans in planets, plus it's red eyes can cause fear on people, mind control multiple lifeforms at once and even put many creatures to sleep.
