Thread about THE MOON

So this week I was playing the game 'To The Moon', which is fantastic (later I'll post my review here). The amazing soundtrack was created by @Reives_Freebird and @supershigi.

When the 'Moon' subject shows up, I always think about the mythology of this celestial object, and also about the differences between languages to refer to this object.

To be exact, what I really think is: why the hell "the moon" is a masculine word in German (der Mond)?

On this matter, I also think about the Sun: why is it feminine in German?

Nonetheless, I'll focus on the Moon in this thread.
