What's all this pro-grade/retro-grade nonsense? Why can't we just accept that some moons "go the other way" without labelling them with culturally loaded terms like Pro and Retro? What if a moon decides to reverse after some cosmic encounter with an astronomical body - does it have to change its name? Do Retro moons have to dress in old clothes from charity shops? Are Pro moons paid more in the Lunar League?
Anyway Jupiter/Zeus liked wine so I propose Chardonne, Lambrine, Spumante, and Prosecca and Cava respectively.
