Ganymede /??æn?mi?d/[12] (Jupiter III) is the largest moon of Jupiter and in the Solar System, and the only moon known to have a magnetosphere. It is the seventh satellite outward from Jupiter[13] and third of the Galilean moons, the first group of objects discovered orbiting another planet. Completing an orbit in roughly seven days, Ganymede participates in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. It has a diameter of 5,268 km (3,273 mi), 8% larger than that of the planet Mercury, but has only 45% of the latter's mass.[14] Its diameter is 2% larger than that of Saturn's Titan, the second largest moon. It also has the highest mass of all planetary satellites, with 2.02 times the mass of the Moon.[15] Additionally, it is the 9th largest object in the Solar System, and the largest without any atmosphere.
Ganymede is composed of approximately equal amounts of silicate rock and water ice.[16] It is a fully differentiated body with an iron-rich, liquid core, and an internal ocean that may contain more water than all of Earth's oceans together.[17][18][19][20][21] Its surface is composed of two main types of terrain. Dark regions, saturated with impact craters and dated to four billion years ago, cover about a third of the satellite. Lighter regions, crosscut by extensive grooves and ridges and only slightly less ancient, cover the remainder. The cause of the light terrain's disrupted geology is not fully known, but was likely the result of tectonic activity brought about by tidal heating.[5]
Ganymede's magnetosphere was probably created through convection within its liquid iron core.[22] The meager magnetosphere is buried within Jupiter's much larger magnetic field and would show only as a local perturbation of the field lines. The satellite has a thin oxygen atmosphere that includes O, O2, and possibly O3 (ozone).[11] Atomic hydrogen is a minor atmospheric constituent. Whether the satellite has an ionosphere associated with its atmosphere is unresolved.[23]
Ganymede's discovery is credited to Galileo Galilei, who was the first to observe it on January 7, 1610.[1][2][3] The satellite's name was soon suggested by astronomer Simon Marius, for the mythological Ganymede, cupbearer of the Greek gods and Zeus's lover.[24] Beginning with Pioneer 10, spacecraft have been able to examine Ganymede closely.[25] The Voyager probes refined measurements of its size, whereas the Galileo craft discovered its underground ocean and magnetic field. The next planned mission to the Jovian system is the European Space Agency's Jupiter Icy Moon Explorer (JUICE), due to launch in 2022. After flybys of all three icy Galilean moons, the probe is planned to enter orbit around Ganymede.[26]
O dancing Ganymede ……..O…..dancing Ganymede
Frozen world passes by
As we see you…with our naked eye.
Vivid dreams out of time
Icy world moving across the sky
Does your Mother Jupiter
Rouse you from your sleep-- and make you speak to her?
Is it true in what she sings?
That you were born when she cast her golden rings.
Winds across your frozen sea
Sing crystal harmonies.
Mother planet reaches out
With arms of magnetic canopy.
You dance around her in the night,
Your moon sisters twirling-- movements with delight.
An ancient dance, a minuet.
