Jupiter has 79 total numbers of moons, in which 26 of them have not been officially named yet. So there are 53 confirmed **Jupiter moons** with its 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.

Here in this article, you can find the most interesting information about the Moons of Jupiter; such as Jupiter moons name, Jupiter moons list, the number of moons, and other unique facts.

**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 the 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 of our solar system. It is approximately 26% larger than the planet Mercury by volume. This satellite of Jupiter is the ninth largest object of 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 to 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 79 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 rings of Jupiter are only contained around 0.003% mass of Galilean moons.

After the first seen of Galilean moons in 1610, no Jupiter moons 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.

**Jupiter moons names and list**

Planet Jupiter has 79 moons, though 7 moons are lost currently. Here you can find a Jupiter moons list with their names. These 79 numbers of moons are mentioned here in order of increasing the distance from Jupiter.
