The Mimas article was wrong on the point of the adjectival form it might be considered correct by some but it s not merely obscure it s a neologism unused anywhere except Wikipedia and most importantly unused by astronomers or the arbiters of astronomical nomenclature the IAU I feel that it is inappropriate to promote the use of a neologism in an encyclopaedia which is supposed to be descriptive rather than prescriptive and so I have removed the reference to the word
