    Natural satellites of the planet Jupiter

    There are 115 known moons of the planet Jupiter as of 9 April 2026. This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. All together, Jupiter's moons form a satellite system, colloquially referred to as the Jovian system.
