Ganymede, or Jupiter III, is the largest and most massive natural satellite of Jupiter, ... Ganymede orbits Jupiter at a distance of 1,070,400 kilometres ...
Ganymede (Jupiter III), the third Galilean moon, is named after the mythological Ganymede, cupbearer of the Greek gods and Zeus's beloved. [41] Ganymede is the largest natural satellite in the Solar System at 5262.4 kilometers in diameter, which makes it larger than the planet Mercury – although only at about half of its mass [ 42 ] since ...
A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] 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. [4]
The surface of Ganymede, a moon of Jupiter moon, is covered by furrows (right) that form concentric circles around one specific spot (left, red cross), which led researchers in the 1980s to ...
Ganymede, the largest of the four, is larger than the planet Mercury. ... [130] [131] The average distance between Jupiter and the Sun is 778 million km ...
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from Jupiter's center and 350,000 km (217,000 mi) from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter.
Voyager 2 passed Io on July 9, 1979 at a distance of 1,130,000 km (702,000 mi), approaching Jupiter between the orbits of Europa and Ganymede. [58] Though it did not approach nearly as close to Io as Voyager 1 , comparisons between images taken by the two spacecraft showed several surface changes that had occurred in the four months between the ...
