Jupiter’s galilean moons are the closest large moons to earth, and are therefore the most easily visible through a small telescope. today, nasa’s juno mission is in orbit around jupiter, getting opportunities to observe some of its moons. its predecessor, nasa’s aptly named galileo spacecraft, studied jupiter and its moons from 1995 to 2003. Io is the innermost and third largest of jupiter’s four galilean moons. io is covered in hundreds of volcanoes. it is the most volcanically active world in the solar system. io can help us understand volcanism and tidal heating throughout the solar system. while all the moons in our solar system have their intriguing characteristics and.
Jupiter's galilean moons nasa's galileo spacecraft captured these images of jupiter's four largest moons. from left to right, they are shown in order from outermost to innermost: callisto in 2001, ganymede in 1997, europa in 1998, and io in 1997. nasa jpl ted stryk. this work is licensed under a creative commons attribution noncommercial. This mosaic shows the surfaces of jupiter’s four galilean moons images, as seen by nasa’s galileo spacecraft. nasa jpl dlr. we know the innermost galilean, pus colored io, is covered in. 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. Juice launched in april 2023, on a mission to study jupiter and three of its four big galilean moons — ganymede, callisto and europa. all three are thought to possess oceans of liquid water.

Jupiter's 4 largest moons exhibit some of the most interesting geology in the solar system. they were discovered by galileo galilei and are known as the galilean moons. jupiter's largest moon, ganymede, is larger than mercury while the other three are larger than pluto. outward from jupiter:. The galilean satellites are — in order of increasing distance from jupiter — io, europa, ganymede, and callisto. in order of decreasing size, they are ganymede, callisto, io, and europa. the inner three of these moons have specially locked orbits that cause them to periodically align in what is called a 1:2:4 orbital resonance.
