@simmo@mastodon.social hmm only thing I can think of is that the moon doesn't really have a name and there are lots of them in the solar system. Mars does have a name, so all the planets and moons that are named eg. Jupiter, Ganymede we don't use 'the'. Should be going to 'a moon's I guess, but probably 'the' because it's earth's only one 🤔
