Astronomers now have the dumbest name possible for a moon that is the moon of another moon

If you look at the night sky, chances are you'll see the only great natural satellite on Earth. We just call it "the moon," but other planets also have moons. Recently, the first evidence of an exomoon – that is, a moon orbiting a planet in another star system – was revealed, but what would happen it if we found a planet with a moon that had its own moon?

This entirely speculative scenario has attracted the interest of several astronomers, who have set themselves the task of defining their own terminology to describe these still unknown objects. The best (or worst?) Candidate so far is so stupid that he has already stormed the Internet: moon storm.

As ScienceAlert explains, the entire discussion regarding moons around other moons is from a pair of documents awaiting publication. The first is the work of astrophysicist Duncan Forgan who took the time to calculate whether the candidate for the exomoon recently studied around the exoplanet Kepler-1625b could potentially be livable.

Forgan explains in his article that even though current observations of exomoon's potential suggest that he would not reside in the habitable zone of the star. However, if the large moon of Neptune's size had its own moon and this moon was a rocky body like the Earth, it could have been inhabited when Kepler-1625 was in its main sequence a long time ago.

This is where we come to the heart of the problem. When Forgan describes the potential of a moon around another moon, he uses the term "moon-moon." It's a silly term to start with, but Moon Moon also turns out to be the hook of a meme that gained popularity in 2013. The gag is the result of one of those awful messages "What is your name ______?" That attempts to give you a new nickname based on the first few letters of your first name and last name. In this particular case, the individual's "werewolf name" ended up being Moon Moon.

Internet culture aside, the research is quite interesting and an article appeared a few days later trying to answer the question of whether a moon could even exist around another moon. Completely avoiding the term "moon-moon" – authors Juna Kollmeier and Sean Raymond prefer "submoon" instead – scientists describe how this might actually be possible. Both articles deserve to be read, but we will have to wait to see with what term the astronomy community will decide to follow.
