Help Name Five Newly Discovered Moons of Jupiter!
In July 2018, Carnegie's Scott Sheppard announced the discovery of 12 new moons orbiting Jupiter—11 “normal” outer moons, and one that he called an “oddball.” This brought Jupiter’s total number of known moons to a whopping 79—the most of any planet in our Solar System.
Now you can help Sheppard and his co-discoverers select the names for five of these newly announced moons!
