Ganymede's surface is composed of two main types of terrain, the first of which are lighter regions, generally crosscut by extensive grooves and ridges, dating from slightly less than 4 billion years ago, covering two-thirds of Ganymede.

2021年11月5日 · Jupiter’s icy moon Ganymede is the largest moon in our solar system, even bigger than the planet Mercury, and the dwarf planet Pluto. There’s strong evidence that Ganymede has an underground saltwater ocean that may hold more water than all …

2021年11月5日 · Jupiter’s moon Ganymede is the largest moon in our solar system, bigger than the planet Mercury and dwarf planet Pluto. NASA’s Hubble Space Telescope has found the best evidence yet for an underground saltwater ocean on Ganymede. The ocean is thought to have more water than all the water on Earth's surface.

Ganymede has a radius of 1,635 miles (2,631 kilometers) and is the largest moon in our solar system. It’s bigger than Mercury and Pluto. Ganymede is about 665,000 miles (1.07 million kilometers) from Jupiter, which orbits about 484 million miles (778 million kilometers) from the Sun. Jupiter is 5.2 astronomical units away from the Sun. One ...

A colony on Ganymede would need to address the moon's extreme environment: low temperatures, intense radiation from Jupiter, and a thin, oxygen-poor atmosphere. Despite these challenges, Ganymede's subsurface ocean and potential resources make it an intriguing candidate for human habitation.

The surface of Ganymede is icy and covered with two main types of landscape: young, lighter regions and darker, older and cratered terrain. The dark areas appear to contain clays and organic materials. Ganymede was likely formed in place …

2024年11月4日 · The photos show the surface of Ganymede in remarkable detail, including craters, clearly distinct dark and bright terrain, and long structural features possibly linked to tectonic faults. This image of Ganymede was obtained by the JunoCam imager aboard NASA’s Juno spacecraft during its June 7, 2021, flyby of the icy moon.

The surface area of Ganymede is 86,999,665.93 Km^2. The surface gravity of the Ganymede is 1.428 m/s². For comparison, the Earth's surface gravity is 9.807 m/s².

Ganymede The Largest Moon of Jupiter And the Solar System Ganymede, one of Jupiter's Galilean moons, has an average distance of about 1,070,400 kilometers from Jupiter. ... The surface gravity on Ganymede is about 1.428 m/s², which is about 14.6% of Earth's gravity—still enough to provide a decent amount of pull. Ganymede's escape velocity ...
