Jupiter has many natural satellites. As of June 2023, Jupiter has **95** confirmed moons.

Moons of Mars

## Groups

### **Regular Satellites**

#### Inner satellites or Amalthea group

Made up of Metis, Adrastea, Amalthea, and Thebe. They orbit very close to Jupiter; the innermost two orbit in less than a Jovian day. The latter two are respectively the fifth and seventh largest moons in the Jovian system.

#### Main Group or Galilean Moons

***See each satellite's dedicated page for further information. Or see the Galilean Moons of Jupiter.***

Made up of Io, Europa, Ganymede and Callisto. These moons have already been implemented into the game. These four make up the vast majority of the Jovian system's mass and are respectively the fourth-, sixth-, first-, and third-largest natural satellites in the Solar System, containing approximately 99.997% of the total mass in orbit around Jupiter, while Jupiter is almost 5,000 times more massive than the Galilean moons.

### **Irregular Satellites**

#### Prograde Satellites

##### Himalia group

Confined within semi-major axes between 11–12 million km (6.8–7.5 million mi), inclinations between 27–29°, and eccentricities between 0.12 and 0.21. It has been suggested that the group could be a remnant of the break-up of an asteroid from the asteroid belt. Made up of Leda, Ersa, Himalia, S/2018 J 2, Pandia, Lysithea, Elara, S/2011 J 3, and Dia.

##### Carpo Group

The Carpo group includes two known moons on very high orbital inclinations of 50° and semi-major axes between 16–17 million km (9.9–10.6 million mi). Made up of: Carpo and S/2018 J 4.

#### Retrograde Satellites

##### Carme Group

This group has tightly confined within semi-major axes between 22–24 million km (14–15 million mi), inclinations between 164–166°, and eccentricities between 0.25 and 0.28. It is very homogeneous in color (light red) and is believed to have originated as collisional fragments from a D-type asteroid progenitor, possibly a Jupiter trojan. Made up of: Carme, Taygete, Eukelade, Eirene, Chaldene, Isonoe, Kalyke, Erinome, Aitne, Kale, Pasithee, and (probably) S/2003 J 9.

##### Ananke Group

The Ananke Group has a relatively wider spread than the previous groups, with semi-major axes between 19–22 million km (12–14 million mi), inclinations between 144–156°, and eccentricities between 0.09 and 0.25. Most of the members appear gray, and are believed to have formed from the breakup of a captured asteroid. Made up of: Ananke, Praxidike, Iocaste, Harpalyke, Thyone, Euanthe, and Eupheme.

##### Pasiphae Group

The Pasiphae Group is quite dispersed, with semi-major axes spread over 22–25 million km (14–16 million mi), inclinations between 141° and 157°, and higher eccentricities between 0.23 and 0.44. The colors also vary significantly, from red to grey, which might be the result of multiple collisions. Sinope, sometimes included in the Pasiphae group, is red and, given the difference in inclination, it could have been captured independently; Pasiphae and Sinope are also trapped in secular resonances with Jupiter. Made up of: Pasiphae, Sinope, Callirhoe, Megaclite, Autonoe, Eurydome, and Sponde.
