Not sure if everyone's heard, but a couple weeks ago, it was announced that Kepler-1625b may have the first known exomoon, or moon around an exoplanet. The interesting thing is that the exomoon may be Neptune-sized. Given that we've had questions here before about massive moons, and the habitability thereof, I was considering writing a post discussing the discovery in a worldbuilding context. What do people think?
