Metis is the closest moon to Jupiter, lying within the main ring it is thought to supply some of the material for the ring.

Adrastea lies with Metis within Jupiter's main ring; it is the second closest moon to the giant planet and is also thought to supply material for the ring.

Amalthea has an unusual shape, measuring about 270 x 165 x 150 km, it has many impact craters, some of which are disproportionately large compared to Amalthea; humans have named the largest of the impacts Pan, it is 100km across and nearly 8km deep - another impact named Gaea is 80km across and thought to be twice as deep as Pan. Amalthea has two mountains known to humans as Mons Lyctas and Mons Ida, they are around 20km tall. Amalthea's orange-ness is thought to be caused by dust from Io. Amalthea continuously receives high doses of energetic ions, protons, and electrons produced by its planet's magnetosphere.

Thebe is Jupiter's fourth known moon, there is very little data on this asteroid-like moon.

Io orbits very close to the cloud tops of Jupiter, bringing it close to an intense radiation belt that bathes the satellite with energetic electrons, protons, and heavier ions. As the magnetosphere of Jupiter rotates, it sweeps past Io and strips away about 1000 kilograms (1 ton) per second of volcanic gases and other materials; Io has a sulfurous surface with many volcanoes with lava flows, lava lakes, and giant calderas or collapsed volcanoes that have undergone an explosive period. Io's interaction with Jupiter causes it to create electricty at a rate of 400,000 volts across its diameter and generating an electrical current of 3 million amperes. Io seems to be a rocky silicate rich body with a dense iron, iron sulfide core that extends halfway to the surface with a partially melted silicate rich mantle, and a thin rocky crust.

Europa has one of the brightest surfaces in the Solar system, caused by the Sun’s rays reflecting off its icy crust. Europa does not have heavy crater impacts like some of its brothers and sisters; it has random-looking lines across its surface and it is thought there may be seismographic activity beneath with a chance of life sustaining water present there.

Ganymede is the largest moon in the Solar System, with a diameter of 5,262 km (3,280 miles); a very thin layer of ozone has been detected on the surface, created by charged particles trapped in Jupiter's magnetic field as they rain down onto Ganymede – the charged particles disrupt ice on the surface which in turn give off the ozone gas, which could mean there is a weak oxygen atmosphere. Ganymede has mountains, valleys, craters and lava flows. The largest moon in the Solar System has many heavy impact craters that suggest Ganymede is very old.

Callisto is the second largest moon of Jupiter, but only the third largest in the Solar System. Created soon after the Solar System was formed, Callisto is around 4 billion Earth years old; it is beyond the influence of Jupiter’s main radiation belt and has more impact craters than any other object in the Solar System. Its surface is icy with no large mountains, a mass of craters upon crater - two very large concentric rings that are impact basins can be found on Callisto, the largest impact basin is known as Valhalla on Earth; it has a bright central region that is 600 kilometres in diameter, and its rings extend to 3000 kilometres in diameter. The second impact basin is know as Asgard by Earth people. It measures about 1600 kilometers in diameter.

There is little data on Leda at this time, it is the ninth and smallest moon of Jupiter.

It is thought that Himalia was once an asteroid that was captured by Jupiter’s magnetic field; it is now the tenth known satellite of Jupiter and the brightest of the outer moons.

There is little data on the majestic looking Lysithea at this time; it is the eleventh moon of Jupiter.

There is little data on Elara at this time with its startling appearance; it is the twelfth satellite of Jupiter.

There is little data on Ananke at this time; it is the thirteenth satellite of Jupiter.

There is little data on Carme at this time; it is the fourteenth satellite of Jupiter.

There is little data on Pasiphae at this time; it is the fifteenth satellite of Jupiter.

There is little data on Sinope at this time; it is the outermost satellite of Jupiter.
