All together, Jupiter's moons form a satellite system called the Jovian system. The most massive of the moons are the four Galilean moons: Io, Europa, Ganymede, and Callisto, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun.

Jupiter is the largest planet in the solar system and has, as of 2023, 95 known moons. The four largest moons of Jupiter—Io, Callisto, Ganymede, and Europa—were the first objects in the solar system discovered with a telescope. Galileo discovered them in 1610, and they are now called the Galilean satellites.

2023年6月8日 · Jupiter, the largest planet in our solar system, boasts a whopping 95 moons, making it the second-most populous planet in terms of its companions (Saturn has the most …

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 …

3 天之前 · These moons – Europa, Io, Callisto, and Ganymede – are called the Galilean moons because they were first spotted by Galileo Galilei in 1610. The moons were individually named by the German astronomer Simon Marius, who discovered them the same year as Galileo.

4 天之前 · Jupiter has 95 moons that have been officially recognized by the International Astronomical Union. But the number doesn’t capture the complexity of the Jovian system of moons, rings and asteroids. The giant planet has thousands of small objects in its orbit.

2022年12月14日 · NASA’s Juno mission is scheduled to obtain images of the Jovian moon Io on Dec. 15 as part of its continuing exploration of Jupiter’s inner moons. Now in the second year of its extended mission to investigate the interior of Jupiter, the solar-powered spacecraft performed a close flyby of Ganymede in 2021 and of Europa earlier this year.

Once presumed to be frigid geologically dead worlds, missions to the outer solar system have shown some of these moons to be dynamic worlds, with active volcanism. Scientists now think that a number of the outer solar system’s moons may harbor liquid oceans.

2024年3月31日 · Jovian moons are the natural satellites that orbit the gas giant planet Jupiter. These moons are also known as the Galilean moons, named after the Italian astronomer Galileo Galilei, who discovered them in 1610. There are a total of 79 known moons orbiting Jupiter, making it the planet with the largest number of moons in our solar system.

Jupiter has four large moons which were discovered by Galileo in 1610 using a 20-power telescope. These moons are known as the Galilean moons and they are called Io, Europa, Ganymede and Callisto. Jupiter also has dozens of other smaller moons that are thought to have originated from passing asteroids. So how many moons does Jupiter have?
