Jupiter's 67 Moons

by Ron Kurtus (updated 18 January 2022)

Jupiter, the largest planet in our solar system, has 67 moons orbiting the planet. Of those moons, 53 are named moons. Fourteen more have been discovered but have not been given official status or names.

(Imagine if the Earth had 67 moons that could be seen in the night sky. That would be weird!)

The first four Jupiter moons discovered are large enough to be seen from Earth with a common telescope. The other moons have been observed with astronomical telescopes and space satellites. The 49 named moons have been thoroughly studied, while the remaining smaller 14 moons still need to be studied.

Questions you may have include:

This lesson will answer those questions.

Four largest moons

The planet Jupiter's four largest moons are:

Each of these moons is larger the our Earth's Moon.

They are called the Galilean moons or satellites after Italian astronomer Galileo Galilei, who first observed them in 1610.

(See Jupiter's Galilean Moons for details.)

Jupiter has 49 other named moons that are smaller than the Gallean moons. Since they are smaller than the major four moons, studies about them is still ongoing.

Astronomers are still studying these smaller moons.


Jupiter has 67 moons orbiting the planet. Of those moons, four are large enough to have been observed by Galileo in 1610, 49 have since been studied and named, and fourteen more have been discovered but have not been given official status or names.
