List of Jupiter's moons

There are 95 known moons of Jupiter, as of 1 November 2023. Jupiter has the second largest number of moons of any planet in the Solar System.[1][2][3]

The most massive of the moons are the four Galilean moons, which were independently discovered in 1610 by Galileo Galilei and Simon Marius. They were the first objects found to orbit a body that was neither Earth nor the Sun. The Galilean moons are by far the largest and most massive objects to orbit Jupiter. The other 91 known moons and the rings together make up just 0.003% of the total orbiting mass. The four are Io, Europa, Ganymede and Callisto. They are roughly the same size as Earth's moon, some are a bit bigger, some are smaller.

From the end of the 19th century, dozens of much smaller Jovian moons have been discovered. All these are less than 250 kilometres (160 mi) in diameter, with most barely exceeding 5 kilometres (3.1 mi). Their orbital shapes range from nearly perfectly circular to highly eccentric and inclined. Many revolve in the direction opposite to Jupiter's spin (retrograde motion). Orbital periods range from seven hours (taking less time than Jupiter does to spin around its axis), to some three thousand times more (almost three Earth years).

List of moons

This list starts with those that go around Jupiter (orbit) the fastest. That is, they have the shortest orbital period. Moons highlighted in purple are the "Galilean moons," moons highlighted in dark gray have a retrograde orbit, and moons with the regular white background have a prograde orbit.

List Of Jupiter's Moons Media

  • A montage of Jupiter and its four largest moons (distance and sizes not to scale)

  • The Galilean moons. From left to right, in order of increasing distance from Jupiter: Io; Europa; Ganymede; Callisto.

  • The relative masses of the Jovian moons. Those smaller than Europa are not visible at this scale, and combined would only be visible at 100× magnification.

  • Jupiter and the Galilean moons as seen through a 25 cm (10 in) Meade LX200 telescope

  • Voyager 1 discovery image of the inner moon Metis on 4 March 1979, showing the moon's tiny silhouette against the backdrop of Jupiter's clouds

  • Galilean moons around Jupiter       Jupiter ·       Io ·       Europa ·       Ganymede ·       Callisto

  • Orbits of Jupiter's inner moons within its rings

  • Orbits and positions of Jupiter's irregular satellites as of 1 January 2021. Prograde orbits are colored blue while retrograde orbits are colored red.

  • Orbital diagram of the orbital inclination and orbital distances for Jupiter's rings and moon system at various scales. Notable moons, moon groups, and rings are individually labeled. Open the image for full resolution.

Notes

  1. ↑ Label refers to the Roman numeral attributed to each moon in order of their discovery.
  2. ↑ Diameters with multiple entries such as "60×40×34" reflect that the body is not a perfect spheroid and that each of its dimensions have been measured well enough.
  3. ↑ Periods with negative values are retrograde.
  4. ↑ "?" refers to group assignments that are not considered sure yet.
