Ganymede a satellite of Jupiter (Jupiter III), is the largest and most massive of the Solar System's moons. Citizen scientist Gerald Eichstädt created this image using data from the JunoCam camera. It is the only moon with any magnetosphere, ability to deflect charged ionizing radiation, making it the only place where dome-grown crops stood a chance in Jupiter's harsh radiation belt besides Callisto. Ganymede is the seventh satellite of Jupiter and the largest moon in the Sol system.It is one of the "Galilean moons", the four largest moons of Jupiter that were discovered by Galileo Galilei. Contrary to Ganymede and Callisto, Europa (diameter 1,940 miles or 3,121 kilometers) has a sparsely cratered surface, indicating that geologic activity took place more recently.
The younger regions are marked with grooves and ridges.
The large circular feature on the upper right, called Galileo Regio, is an ancient region of unknown origin. Astronomers believe this is caused by the icy surface flowing over time. During the encounter Galileo recorded data that hint at a liquid saltwater ocean hidden beneath Ganymede's icy crust. Many structures have been found on These are believed to have been formed by tectonic forces very similar to those that shape the surface of the Earth. Ganymede ( / ˈ ɡ æ n ɨ m iː d /) [12] is a satellite of Jupiter and the largest moon in the Solar System.It is the seventh moon and third Galilean satellite outward from Jupiter. It begins with a brief view of the lunar orbit around Earth. Ganymede has a thin oxygen atmosphere. Contrary to Ganymede and Callisto, Europa (diameter 1,940 miles or 3,121 kilometers) has a sparsely cratered surface, indicating that geologic activity took place more recently. It has a diameter of 5,268 km (3,273 mi) and is 8% larger than the planet Mercury.Possessing a metallic core, it is the only moon known to have a magnetic field. For this reason, some astronomers believe that Ganymede is … It has a magnetic field that is similar to the one of Callisto.
To compare this temperature map to surface features of Ganymede, you can look at this Ganymede Image taken during the Ganymede 1 orbit. Because we know that there is an ocean under Europa’s surface and its approximate volume, scientists have used the overall density of Europa to assume that there is a solid core under the ice that is half as wide as the moon’s total diameter. Since Ganymede is about 5,300 miles across, the solid core would be about 2,650 miles across. The surface area of Ganymede is 86,999,665.93. Ganymede, with a diameter of about 3,300 miles or 5,268 kilometers (one-and-a-half times larger than the Earth's moon), is the largest moon in the solar system.
Ganymede's surface is rich with liquid water. Cassini was 26.5 million kilometers (16.5 million miles) from Ganymede when this image was taken. The surface of Ganymede is halfway between that of Callisto and that of Europa.Portions of the crust are of ancient age, while other portions are relatively new..
The ninth largest object in the Solar System, it is the largest without a substantial atmosphere. The little white dots shown in this image are the many imact craters on Ganymede. I think there might be some sort of life on Ganymede but not humans. The is the average distance in km of the object is from its parent 1070400.00. Surface temperatures on Ganymede average -171 F to -207 F during daytime areas and at night it can reach -193 C. The surface gravity of the said item is 1.428. Galileo last visited Ganymede in May, 2000, when it skimmed 800 kilometers over the moon's surface. Ganymede: the surprisingly magnetic moon Wayne Spencer T he largest moon in the solar system is Ganymede, at Jupiter. Ganymede is about 200 km larger in radius than the planet Mercury. The smallest visible features are about 160 kilometers (about 100 miles) across. Scientists have even found evidence for an underground ocean of liquid water beneath its icy surface. Jupiter's moon Ganymede, larger than even Mercury and Pluto, has an icy surface speckled with bright young craters overlying a mixture of older, darker, more cratered terrain laced with grooves and ridges. The Mean orbit velocity, that is the speed at which it orbits is 39165.60 km/h.
