Of Jupiter's 80 moons, 57 are official and 23 are waiting to be confirmed by the International Astronomical Union.

When Galileo first observed Jupiter's moons in 1610, they were the first of their kind.

The majority of Jupiter's moons are small, with less than 10 kilometers in diameter. The outer moons may have been captured by Jupiter's gravity after the initial system was formed.

There are 10 weird moons in the sun.

Galilean moons: Jupiter's biggest satellites

1. Ganymede  

The diameter is 3,270 miles.

The moon of Jupiter is larger than the planet Mercury. It is the only moon in the world that has its own magnetic field, which makes it a great place to watch the Auroras. According to NASA Science, the giant moon has the potential to hold more water than all the water on Earth's surface.

2. Europa  

The diameter is 1,940 miles.

There is an iron core, rocky mantle and a surface of frozen water ice on top of the ocean. According to NASA, the most promising place to find an environment that could support life is the icy moon Europa. The saltwater ocean could hold twice the amount of water as Earth's oceans combined and have existed for a long time.

3. Io

The diameter is 2, 260 miles.

Io is the most volcanically active place in the solar system and is locked in a tug-of-war between Jupiter's gravity and neighboring moons. The turbid environment is constantly renewing itself, smoothing out craters with vast lakes of lava from one of the hundreds of volcanoes that blanket the landscape.

4. Callisto 

The diameter is 2,995 miles.

Callisto is Jupiter's second largest moon. The oldest surface in the solar system is believed to be the moon. It comes as no surprise that Callisto is the most heavily cratered body in the solar system.

Guests are familiar with the Jovian system. Jupiter has attracted numerous flybys and close encounters from trailblazing probes since the first visitor in 1973. The closest approach to Jupiter by Pioneer 11 was a year after Pioneer 10 in December 1974.

The Jovian system finally had a guest stay from NASA's Galileo in December 1995 Galileo was the first to go to Jupiter and he made a lot of discoveries. There is a possible ocean on Jupiter's icy moon Europa, as well as volcanoes on the moon Io. Galileo crashed into the gas giant at the end of its stay in September 2003 in order to prevent a collision.

In 1992 and 2004 Jupiter was used for a couple of gravity-assisted maneuvers by the NASA-ESA Ulysses mission. Around 26,000 images of the gas giant were collected by Cassini when it was close to Jupiter. During its trip to the dwarf planet, NASA's New Horizons discovered impressive nighttime auroras and lightning at the planet's poles.

The Jovian system is being explored by NASA. The composition, atmosphere, gravity and magnetic field of Jupiter are some of the things that are being investigated by the mission. The solar system's origin and evolution will be learned by Juno.

The Jupiter Icy Moons Explorer is due to be launched in April of 2023. The mission will look at Jupiter and its moons. It will be joined by the NASA's Europa Clipper mission. The goal of the mission is to investigate whether the strange world harbors conditions that could accommodate life.

How to see Jupiter's moons for yourself

It is possible to see Jupiter and its moons with the right equipment. The best times to view the planets is in our visible planets guide.

You can see Jupiter with a pair of binoculars or a small telescope at this brightness. Lower numbers mean brighter objects. Venus shines with a magnitude of about -4. You will need a small telescope or binoculars to see the moons.

If you want to find out where and when to look out for Jupiter's moons, you should use skywatching apps. We have picked the best stargazing apps.

Our best telescopes for seeing planets guide can help if you want to see Jupiter and its moons. If you're looking for a bargain, we have guides on the best binoculars and telescopes.

Additional resources

If you want to learn more about the mission to Jupiter's icy moons, you can watch this video. There is an article in the EU Research and Innovation magazine called "Is there life on Jupiter's moons?" Do you think you have found a new moon? There is a guide to the most common objects that you may have observed as well as information on how to report your findings.
