Jupiter Moons: Names & List of Number of Moons

Jupiter has 80 total numbers of moons, of which 23 have not been officially named yet. So there are 57 confirmed Jupiter moons with their official names.

Jupiter is the largest planet in our solar system and also it has the largest moon in our solar system. Four ‘Galilean Moons’ (Ganymede, Callisto, Io, and Europa) are the largest moons of Jupiter.

Planet Jupiter has 4 inner moons ( Metis, Adrastea, Amalthea, and Thebe), whose orbits are very close to Jupiter.

Moons of Jupiter

Facts & Information

Jupiter’s Galilean Moons were the first discovered moons after the earth’s moons and were the first known objects to orbit a planet after the earth’s moon.

Galilean moons were first discovered by ‘Galileo Galilei’ in 1610 and soon after seen by ‘Simon Marius’. Before discovering Galilean Moons, scientists did not know that any object orbits a planet other than the earth’s moon.

Jupiter’s moon ‘Ganymede’ is the largest and most massive moon in our solar system. It is approximately 26% larger than the planet Mercury by volume. This satellite of Jupiter is the ninth largest object in our solar system, after the sun and seven planets.

The four Galilean moons and four inner moons (Metis, Adrastea, Amalthea, and Thebe) of Jupiter are called regular satellites. These eight moons have prograde motion and orbit relatively near Jupiter. Whereas the other moons of Jupiter are called irregular satellites. These irregular satellites of Jupiter have high eccentricity with their prograde and retrograde motion and have much inclination to Jupiter’s plane.

Though there are 80 known moons of Jupiter, but currently some of Jupiter’s moons are lost (currently 7 satellites are lost).

Galilean moons are so large and massive that even the other 45 jovian moons including the rings of Jupiter are only contained around 0.003% mass of Galilean moons.

In the Galilean Moons of Jupiter, Moon IO is the closest and Callisto is the farthest to the Planet. Whereas Europa is the smallest and Ganymede is the largest of the Planet Jupiter. These heavy and large Jupiter Moons made this planet different. Check the image below for reference:

After the first scene of Galilean moons in 1610, no Jupiter moons were observed until 1892. In 1892 an American astronomer Edward E. Barnard discovered the inner satellite ‘Amalthea’. Whereas the Voyager spacecraft discovered the other three inner moons of Jupiter.

“Some of Jupiter’s moon can collide in the future after millions of years, because of their prograde and retrograde orbits”.
