Well, if you’re a scientist, lack a bit of imagination and have no clue about internet memes.... you call them *drummroll*:

Moonmoons.

At least according to astronomers Sean Raymond and Juna Kollmeier , who are working on a paper on the topic if moons can have moons. Official recognition from the International Astronomical Union still pending.

Given the above mentioned meme, I’d recommend an internet poll. Which will naturally end with Moony McMoonface, but still better than Moonmoon.

[If you don’t know what meme I’m talking about, here it is.]
