Jupiter is the fifth planet closest to the Solar after (Mercury, Venus, Earth, Mars) and it’s a gaseous planet in composition and composition and it’s the largest and largest planet within the photo voltaic system when it comes to measurement, mass and gravitational drive. , so there are numerous moons of Jupiter and since it comprises the strongest magnetic discipline, so any asteroid passing close to it’s both captured in considered one of its orbits or destroyed. Most of Jupiter’s moons are both fashioned by collisions or are captured asteroids.

What number of moons does Jupiter have?

There are various satellites revolving round Jupiter with totally different orbits, 79 satellites in complete, and 53 of them have been named and their names have been chosen by the Worldwide Astronomical Union (IAU) in reference to a Greek or Roman historic determine.

Forms of Jupiter’s moons

Jupiter’s satellites are divided into two sorts: common common satellites and irregular satellites:

1 – Peculiar Peculiar Moons

It has round progressive orbits, which suggests it rotates in the identical route as Jupiter’s rotation and has a low inclination. Additionally it is characterised by a spherical form and is split into two primary teams:

A – Galilean moons

How many moons does Jupiter have?

It’s the largest and most necessary of the 4 moons orbiting Jupiter as found by the astronomer Galileo Galilei in 1610. We organize them from nearest to farthest from Jupiter as follows: IO, Europa, Ganymede, Callisto.

Io, Europa, and Callisto are bigger than Earth’s moon, and Ganymede is the most important moon within the photo voltaic system.

Yo Moon

Io has a diameter of 3642 km and is the third largest of Jupiter’s moons. The satellite tv for pc Io performs an necessary function in modulating the radiation waves emitted by Jupiter. This planet is characterised by its volcanic exercise, since there are numerous volcanoes which are characterised by their power and violence when lava is ejected a number of kilometers above the floor of this moon.


With a diameter of 3121.6 km, it’s the fourth largest of Jupiter’s moons. It is an icy rocky moon. The higher half consists of stable ice, whereas the decrease half is a liquid water ocean. It’s characterised by longitudinal strains that cross on its icy floor, which is soil hooked up to ice, giving it a darkish earthy coloration.

The floor of Europa is the smoothest within the photo voltaic system.

Moon of Ganymede

It’s the largest moon within the photo voltaic system with a diameter of 5262.4 km, which is bigger than the planet Mercury, and the one one with a magnetic discipline. .

callisto moon

It has a diameter of 4820 km and is the second largest satellite tv for pc within the photo voltaic system, consisting of an equal variety of rocks and ice.

B – Inner satellites

It is a group of small satellites lower than 200 km in diameter, positioned at a distance of 127,000-220,000 km from Jupiter, so as from close to to far:

moon title fall in kilometers Distance from Jupiter in km
Metis 40 127 960
Adrastea twenty 128 980
Amalthea 188 181 300
Being 100 221 900

2 – incorrect moons

They’re very small, have totally different shapes and orbits away from Jupiter. These moons have been fashioned because of collisions or have been asteroids captured by Jupiter’s gravity.

Scientists referred to as this group (retrograde cycle).

Every group of moons in the same orbit is called after the most important moon within the group, for instance:

  • Himalia مجموعة: Named after the group’s largest moon, the Himalayas, which has a diameter of 186 km, this group has progressive orbits, which means it orbits in the identical route as Jupiter.
  • Carme Group: Named after the most important moon within the group, Karem, which has a diameter of 40 km, this group has retrograde orbits, which implies that it orbits reverse Jupiter’s orbit, and can also be related in look and is crimson in coloration.
  • Assortment Ananke: Named after the most important moon within the group, Ananke, which has a diameter of 30 km, is a gaggle of 15 moons which have undergone many collisions and different shapes, have retrograde orbits, and are grey in coloration.
  • Assortment Pasithea: Named after the most important moon within the group, the Pacific Ocean, which has a diameter of fifty km, these satellites have been fashioned because of collisions, have varied irregular shapes and take their coloration from crimson and grey, and these satellites have retrograde orbits.
  • As well as, there are numerous irregular moons that don’t belong to a selected group.
