Jupiter's Ring Rings of gas encircle her throne. Like a combination lock, They rotate alone! From afar it's not very easy to tell. Her true nature and size, 74 moons locked in her spell! On these moons, we spent a cold summer. Europa for some, IO for another! From here we studied her Gossamer rings. Made of remnants of old moons, That collided close to the King! The King of the Planets and the first to form. From gasses that existed, When the universe was born. Her gravitational pull and chemical composition. Made any attempt to land, A deadly and impossible mission! Aptly named, The bringer of Jollity. The Lord of our Solar System, Magnificent in eternal ferocity! Four Rings they are. One to rule them all.. Together they stand. For one and for all!
