This is a random question, I didn't know where to ask it.
I noticed a few questions asked on Wordbuilding SE used "Luna" instead of "the Moon".
Is this common in SciFi ?
Where does this usage come from (scientific world, scifi literature...) ?
Worldbuilding is cool and clearly I love it...but there's a certain satisfaction to be had from building a new product and watching it work on the first boot.
