Orbits of Jupiter's 71 irregular satellites as of 1 January 2021, each of them labeled. Their orbits are colored based on their direction of orbits; prograde satellites are colored blue while retrograde satellites are colored red. The lost satellite S/2003 J 10 is given a darker shade of red. Orbits are calculated from JPL-HORIZONS elements based on epoch JD 2459200.5 (17 Dec 2020).
For comparison, the orbit of Galilean moon Callisto (dark green) is shown in the center.
