The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with
Ganymede and Europa are two of the four largest moons orbiting Jupiter, known as the Galilean moons. Europa is similar in size to Earth’s Moon, while Ganymede is the largest moon in the whole ...
Ganymede participates in orbital resonances with Europa and Io: for every orbit of Ganymede, Europa orbits twice and Io orbits four times. [41] [42] Conjunctions (alignment on the same side of Jupiter) between Io and Europa occur when Io is at periapsis and Europa at apoapsis. Conjunctions between Europa and Ganymede occur when Europa is at ...
Study of Ganymede's intrinsic magnetic field and its interactions with the Jovian magnetosphere. For Europa, the focus is on the chemistry essential to life, including organic molecules, and on understanding the formation of surface features and the composition of the non-water-ice material. Furthermore, Juice will provide the first subsurface ...
During this observation, the three stars in a line to the west of Jupiter were (from east to west): Io, Europa, and Ganymede. [9] This was the first time that Io and Europa were observed and recorded as distinct points of light so this date, January 8, 1610 is used as the discovery date for the two moons by the International Astronomical Union ...
A radio-science experiment analyzed Ganymede's gravitational field and internal structure. G1 and G2 radio-science and other data revealed that Ganymede had an interior that was probably differentiated into a core and a mantle. The plasma wave experiment and magnetometer data gave evidence of an internally generated magnetic field. C3 1,136 (705)
Ganymede is the largest moon in the Solar System and has an internal ocean that may contain more water than all of Earth's oceans together. [ 8 ] [ 9 ] The orbiter would perform 13 flybys of Ganymede, and 4 flybys of Callisto and carry up to 50 kg (110 lb) of scientific instruments, while the Europa lander would have carried up to 70 kg (150 lb ...
In this phase Juno began to examine Jupiter's inner moons, Ganymede, Europa and Io. A flyby of Ganymede occurred on June 7, 2021, 17:35 UTC, coming within 1,038 km (645 mi), the closest any spacecraft has come to the moon since Galileo in 2000. [23] [24] [57] A flyby of Europa took place on September 29, 2022, at a distance of 352 km (219 mi).
