Jupiter's four largest moons are called (from closest to furthest); Io (pronounced 'eye-oh'), Europa, Ganymede (the largest, and the largest moon in our solar system) and Callisto. These are also known as the Galilean satellites.
All four of Jupiter's largest satellites were discovered by Galileo.
The person who first saw and described these was Galileo Galilei and they are therfore called the "Galilean Moons".
Galileo Galile
The 4 largest satellites of Jupiter. The (first) four seen by Galileo.
Only Jupiter, the Galilean moons are the four largest moons of Jupiter which Galileo discovered.The four satellites discovered by Galileo orbit Jupiter.
Because someone - Galileo Galilei - looked through the new wonder tool - the telescope - and saw four - he thought they were stars at first - but later realised they were moons of Jupiter.
The four satellites are Jupiter's largest moons. They were found by Galileo Galilei. They are Callisto, Europa, Ganymede and Io.
The four largest moons of Jupiter are called the Galilean satellites, because they were discovered by Galileo when he first observed Jupiter with a telescope. Their names are: * Io * Europa * Callisto * Ganymede

Jupiter was known by the ancients. In 1610, Galileo, discovered that i twas not a point source and had four other bodies orbiting around it, moons.
Jupiter has a whole lot of moons including four big ones discovered by Galileo in the 16th century. He was the first one to use a telescope to study Jupiter. Other than those four, all the others are small and were discovered when spacecraft were sent to Jupiter in the 1970s.
Jupiter has 63 satellites/moons. But it has 4 large one known as: 1. Ganymede (largest in the Solar System) 2. Io (most geologically active body in the Solar System) 3. Europa (has ice and rocks on its surface) 4. Callisto (contains many craters)

The same amount as there are now [See related question] . Galileo Galilei in 1610 only observed the four large moons called the Galilean moons.
Jupiter has 66 natural satellites. Of these, 50 are less than 10 kilometres in diameter and have only been discovered since 1975. The four largest moons, known as the "Galilean moons", are Io, Europa, Ganymede and Callisto.
