 | | The inner group of Metis, Adrastea, Amalthea, and Thebe are small- to medium-sized, orbit in nearly-circular paths at less than 200,000 km, and were discovered by Voyager. |
 | | The third group includes Leda, Himalia, Lysithea, and Elara, which were discovered in the 20th century but pre-Voyager, and S/2000 J11; all have diameters of less than 200 km and orbits of 11 to 13 million km with inclinations of 26-29°. |
 | | It is thought that the three groups of smaller moons may each have a common origin, perhaps as a larger moon or captured body that broke up into the existing moons of each group. |
