Perhaps you mean Dysnomia, a moon of Eris. The moon goes around the dwarf planet once every 15.8 days. I don't think its actual rotation has been observed, but if we assume that its rotation is synchronized with its revolution (as is the case with many moons), that would also be 15.8 days.
Eris has one natural satellite, it is called Dysomia.
