Carnegie's Scott Sheppard has just announced the discovery of 20 new moons orbiting Saturn, bringing its total to 82 and moving it ahead of Jupiter, which has 79. All hail the new king of moons!

Earlier this year we held a contest to name five Jovian moons discovered by Sheppard last July. We loved the enthusiasm everyone showed for this contest so much that we’re doing it again. Please help us name all 20 Saturnian moons!

Contest Launch Date:

October 7, 2019

Contest End Date:

December 6, 2019

How to Submit: 

Tweet your suggested moon name to @SaturnLunacy and tell us why you picked it. Photos, artwork, and videos are strongly encouraged. Don't forget to include the hashtag #NameSaturnsMoons.

The General Rules:

We hope you know a lot about giants, because that’s the key to playing the name game for Saturnian moons.

  • Two of the newly discovered prograde moons fit into a group of outer moons with inclinations of about 46 degrees called the Inuit group. All name submissions for this group must be giants from Inuit mythology.
  • Seventeen of the newly discovered moons are retrograde moons in the Norse group. All name submissions for this group must be giants from Norse mythology.
  • One of the newly discovered moons orbits in the prograde direction and has an inclination near 36 degrees, which is similar to those in the Gallic group, although it is much farther away from Saturn than any other prograde moons. It must be named after a giant from Gallic mythology.
