What are the two distinct types of terrain on Ganymede?
(Ganymede is the only solar system satellite with a magnetic field.) The surface comprises two principal types of terrain, one dark and one bright. The dark terrain is present in broad, roughly polygonal regions that are separated by bands of bright terrain. Both terrains have impact craters.
What is unique about Ganymede moon?
Ganymede is the largest moon in the solar system, and is larger than the planet Mercury. If it were not orbiting as Jupiter’s largest moon, it could be considered a dwarf planet. Ganymede is the only moon in the solar system known to have a substantial magnetosphere.
What is the terrain on Ganymede?
Ganymede’s surface is a mixture of two types of terrain. Forty percent of the surface of Ganymede is covered by highly cratered dark regions, and the remaining sixty percent is covered by a light grooved terrain, which forms intricate patterns across Ganymede.
What is Ganymede larger than?
Jupiter’s moon Ganymede is the largest satellite in the solar system. Larger than Mercury and Pluto, and only slightly smaller than Mars, it would easily be classified as a planet if were orbiting the sun rather than Jupiter.
Which is bigger Ganymede or earth?
Ganymede is the largest and most massive moon in the Solar System. Its diameter of 5,268 km is 0.41 times that of Earth, 0.77 times that of Mars, 1.02 times that of Saturn’s Titan (Solar System’s second largest moon), 1.08 times Mercury’s, 1.09 times Callisto’s, 1.45 times Io’s and 1.51 times the Moon’s.
Is Ganymede bigger than Titan?
Titan is the second largest moon in our solar system. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.
What is the Colour of Ganymede?
brownish-gray
The brownish-gray color is due to mixtures of rocky materials and ice. Bright spots are geologically recent impact craters and their ejecta.
Which is bigger Ganymede or Earth?
What is the size of Ganymede?
1,636.8 mi
Ganymede/Radius
How big is Ganymede vs Earth?
What kind of terrain is found on Ganymede?
The global geography of Ganymede is shown in this view obtained from 2.5 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. The large, dark, oval-shaped mass is Galileo Regio.
How big are the palimpsests of Ganymede Solar System?
Palimpsests range from 30 to 250 miles (50 to 400 kilometers) in diameter. Both bright and dark rays of ejecta exist around Ganymede’s craters – rays tend to be bright from craters in the grooved terrain and dark from the dark cratered terrain.
Why does Ganymede have bright spots on its surface?
While most of Ganymede is relatively brownish in color, possibly due to the contamination of the icy surface by meteoritic material, these polar frosts are more neutrally colored. Bright spots are fresh, young impact craters and their ejecta patterns.
Which is larger the planet Mercury or Ganymede?
With a diameter of 5268 kilometers, Ganymede is the largest satellite in the solar system and larger than the planet Mercury. Ganymede and Callisto are similar in size and density. Yet compared to “boring” Callisto, Ganymede has a very complex geologic history.
