The four largest satellites of Jupiter are known as the Galilean moons: Io, Europa, Ganymede, and Callisto. Io is the most geologically active body in the solar system, Europa is believed to have a subsurface ocean that may harbor life, Ganymede is the largest moon in the solar system, and Callisto is known for its heavily cratered surface. These moons were discovered by Galileo Galilei in 1610 and have since been the focus of extensive scientific study.
Jupiter has 53 named satellites - the biggest is Europa.
The four biggest satellites of Jupiter are Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon in the solar system and is even bigger than the planet Mercury. These four moons are known as the Galilean moons, named after Galileo Galilei who discovered them in 1610.
Jupiter
The four satellites are Jupiter's largest moons. They were found by Galileo Galilei. They are Callisto, Europa, Ganymede and Io.
Jupiter has four large satellites, but they are not the four largest in the solar system. Jupiter has the largest, 3rd, 4th, and 6th largest satellites. Saturn has the 2nd largest and Earth has the 5th largest satellite. (Naturally I mean "natural satellites", otherwise called moons.)
Only Jupiter, the Galilean moons are the four largest moons of Jupiter which Galileo discovered.The four satellites discovered by Galileo orbit Jupiter.
Io, Europa, Callista, Ganymede
The Earth's Moon, Jupiter's four "Galilean" satellites, Saturn's "Titan", and Neptune's "Triton".
Jupiter has 63 moons or satellites.
Jupiter has the most satellites in our solar system, with a total of 79 known moons. These moons vary in size, with the four largest being Io, Europa, Ganymede, and Callisto.
Jupiter holds the record for the most moons in our solar system, with a total of 79 confirmed natural satellites. These moons vary in size, with the four largest being the Galilean moons Io, Europa, Ganymede, and Callisto.
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.
