Excitingly, a contest has been created for the public to choose names for the 20 moons. Sorry, but Saturn McMoonyFace won’t be allowed, as the names have to conform to their mythological groupings, along with other naming conventions.


Welcome new moons! We look forward to learning your new names.

Correction: A previous version of this article stated that one of the new moons has an orbital period of 5.3 years. The correct figure is 3.87 years. We regret the error.
