What are the surface features of Ganymede?
Surface. Spacecraft images of Ganymede show its surface is a mix of two types of terrain. Forty percent of the surface is covered by highly cratered dark regions, and the remaining sixty percent is covered by a light grooved terrain, which forms intricate patterns across the moon.
What is Ganymede surface?
Ganymede’s surface is a mix of two types of terrain: very old, highly cratered, dark regions and somewhat younger (but still ancient), lighter regions marked with an extensive array of grooves and ridges.
What are two facts about Ganymede?
Facts about Ganymede
Age: Ganymede is about 4.5 billion years old, about the same age as Jupiter. Distance from Jupiter: Ganymede is the seventh moon and third Galilean satellite outward from Jupiter, orbiting at about 665,000 miles (1.070 million kilometers). It takes Ganymede about seven Earth-days to orbit Jupiter.
Does Ganymede have rings?
The results revealed that almost all of these furrows on the surface of Ganymede appear to be in concentric rings centered at a single point, indicating that this global multiring structure may be the remains of a giant crater. The radial extent of the multiring measured along the satellite’s surface is 7800km.
What are 3 interesting facts about Ganymede?
Below are some more interesting facts about Ganymede:
- – Ganymede is named after a Trojan prince.
- – Ganymede should be a planet, but isn’t.
- – Ganymede has an orbital period of 7.1 days.
- – Ganymede has its own magnetic field.
- – Ganymede may have a buried ocean.
- – Ganymede has an atmosphere.
- – Ganymede is made of rock and ice.
Can you breathe on Ganymede?
THIN ATMOSPHERE
There’s evidence Ganymede has a faint oxygen atmosphere. It would still be far too thin to breathe, though.
What is Ganymede made out of?
The surface of Ganymede, the largest moon in the solar system, is composed of half water ice and half rock. This satellite of Jupiter is unique for its long, curved grooves in the crust, that make it unlike any other planetary body ever seen.
Why does Ganymede have lines on it?
If such a string of comet fragments hit one of the satellites on its way out of the Jupiter system, it would form a line of closely spaced impact craters called a catena, and these are in fact observed on the surfaces on Ganymede and Callisto.
What are 5 facts about Ganymede?
Is there life on Ganymede?
Yes, it’s very very unlikely that we have substantial life processes occurring on the surface of Ganymede. But when we look at the atmosphere in detail — as a new study recently did with archival data from Hubble — we find that Ganymede’s atmosphere has hydrosignatures in it: copious amounts of water vapor.
What is unique about Ganymede moon?
Ganymede is the only moon known to have its own magnetic field – something typically found on planets like Earth. The magnetic field causes auroras, or bright ribbons of glowing gas, that circle the moon’s poles.
Can humans breathe Ganymede?
What moon could we live on?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
Can we terraform Ganymede?
It’s possible that Ganymede has liquid water under the surface. If this is correct, it could be terraformed and heated by adding greenhouse gases such as Sulfur Hexafluoride and Nitrogen Trifluoride.
Can humans fly on Titan?
Humans would be able to take flight off the surface of Saturn’s moon Titan simply by running in a wingsuit — but only if they were as fast as sprinter Usain Bolt, a group of physics students say.
Does it rain on Titan?
While Earth rain falls at about 20 miles per hour (9.2 meters per second), scientists have calculated that rain on Titan falls at about 3.5 miles per hour (1.6 meters per second), or about six times more slowly than Earth’s rain. Titan’s raindrops can also be pretty large.
Can humans breathe on Ganymede?
Which planet is easiest to terraform?
While Venus, Earth, Mars, and even the Moon have been studied in relation to the subject, Mars is usually considered to be the most likely candidate for terraforming. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject.
Is there gold in Mars?
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts. It is quite possible that in some places these materials may be concentrated enough to be mined economically.
What planet that has oxygen?
There is only one planet where gaseous oxygen is found: Earth! And the only reason that Earth has oxygen is because Earth has plants that do photosynthesis. There is no other natural process that we know of that will put significant amounts of oxygen into a planet’s atmosphere.
What planet rains rubies?
Tidally locked hot Jupiter WASP-121b has an atmosphere so hot on one side that it breaks down water molecules and rains rubies and sapphires.
Does it rain for 7 years on Venus?
Since Venus does not experience rainfall (except in the form of sulfuric acid), it has been theorized that the lightning is being caused by a volcanic eruption.
Which planet has most oxygen?
Problem 3 – Which planet has the atmosphere with the greatest percentage of Oxygen? Answer: From the table we see that Mercury has the greatest percentage of oxygen in its atmosphere.
Can there be life on Ganymede?
Bigger than Mercury and only slightly smaller than Mars, Ganymede may host more water than all of Earth’s oceans in a subterranean ocean about 100 miles/ 160 kilometres below its crust. It’s thought that single-cell microbial life—extremophiles—could exist there.
What planet rains diamonds?
On Saturn it occasionally rains diamonds.
