The lighter region, according to scientists, is far younger. And there are much younger areas marked by grooves and look like filled in cracks.
Jupiter rising over Ganymede with Io and Europa. Daytime temperatures on the surface average minus degrees Fahrenheit to minus F, and night temperatures drop to C.
Ganymede has an infinitesimal atmosphere. The intrinsic field strength at the poles is two times that at the equator— nT. Adnez Generally speaking, Adnez is rather similar to Earth.
The field strength of the induced field at the magnetic equator is about 60 nT—half of that of the ambient Jovian field. Interestingly, scientists say that it may be possible that Ganymede actually has two layers of underground ocean of salt water.
Facts about Ganymede Age: However, anything large that breaches the frozen surface causes water to fill it. One explanation is that the same orbital resonances proposed to have disrupted the surface also allowed the magnetic field to persist: Ganymede has an interesting feature.
It was the Voyager craft that proved that Ganymede was the largest moon. The craters Gula and Achelous bottomin the grooved terrain of Ganymede, with ejecta " pedestals " and ramparts. The upper limit on the surface particle number density was found to be 1. The primary landmark on Ganymede is a large crater called Anat.
And only then, only after I had felt that first rush of improbable carnal lust, did it occur to me that this angel was a man. Where a break or crack occurs, the frozen slush rises up and fills in the crack creating a relatively smooth groove that runs for hundreds of miles. Adnez Tectonics and Currents.
Voyager 1 flew close to Ganymede on its journey through the solar system. However, this magnetic field cannot be easily recognized because it is totally embedded within the massive magnetosphere of Jupiter.
In the s, NASA scientists first suspected that Ganymede has a thick ocean between two layers of ice, one on the surface and one beneath a liquid ocean and atop the rocky mantle.Mar 19, · Geography.
This section will give an overview of each planet, and each continent thereon (presuming the planet has continents), as well as a description of. Geography of Ganymede. We know that Ganymede has a liquid water ocean under its icy exterior.
Ganymede does not have a volcanic core heated by the decay of radioactive elements like Earth and Venus. Instead, Ganymede’s core is heated by the gravitational tug of war between Jupiter and the other moons around Jupiter. Ganymede is the only moon. Ganymede The global geography of Ganymede is shown in this view obtained from million kilometers by Voyager 2.
The surface is roughly equally divided between relatively dark terrain, which is heavily cratered and relatively old, and bright terrain, which is younger and has been deformed tectonically.
Most interesting of Ganymede facts is that it is the only moon in entire solar system to have its own magnetosphere or magnetic field. Ganymede / ˈ ɡ æ n ɪ m iː d / (Jupiter III) is the largest and most massive moon of Jupiter and in the Solar currclickblog.com ninth largest object in the Solar System, it is the largest without a substantial atmosphere.
It has a diameter of 5, km (3, mi) and is 8% larger than the planet Mercury, although only 45% as massive. Possessing a metallic. Ganymede The global geography of Ganymede is shown in this view obtained from million kilometers by Voyager 2. The surface is roughly equally divided between relatively dark terrain, which is heavily cratered and relatively old, and bright terrain, which is younger and has been deformed tectonically.Download
