Assuming an ISS like situation, every time the moon is showing, it’s a full moon, no? Or do orbiting bodies still see it as crescent, waning, etc because it’s still just in the shadow?
But then what if the werewolf is on an interplanetary expedition? What about Io, Ganymede, Europa, etc? Is it only our moon that causes lycanthropy to, y’know, wolf out? Or is it any moon? What if it is only our moon, then it seems like lycanthropes would be on the top of the list as either experimental pilots or just travelers.
What say you all?


The ISS orbits at about 400km. The distance to the moon is about 385,000km. From the moon, and especially the sun, the Earth and ISS are basically in the same place, so the phase of the moon doesn’t appreciably change in low earth orbit.
A werewolf on Europa (and others) could be in a full moon much more often. Even on the side facing away from the sun, it may still have plenty of light due to the reflection from Jupiter.
Maybe they would have to hide away from society once per month whenever they turn into a human monster?
Movie idea: The wolf people of Europa decide to invade Earth but when they get here, their plot is foiled when they turn into humans.
