Ganymede. Ganymede is the largest moon in the solar system (larger than the planet Mercury), and is the only moon known to have its own internally generated magnetic field.
What are the top 5 largest moons?
| Largest moons in the Solar System (diameter over 1,000 km) | ||
|---|---|---|
| Moon | Planet | Mass (planet = 1) |
| Ganymede | Jupiter | 7.80 x 10–5 |
| Titan | Saturn | 2.37 x 10–4 |
| Callisto | Jupiter | 5.67 x 10–5 |
How big is Titan vs Earth?
Frequently described as a planet-like moon, Titan is 50% larger (in diameter) than Earth’s Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter’s moon Ganymede, and is larger than the planet Mercury, but only 40% as massive.
Are any moons bigger than Earth?
Titan is the second largest moon in our solar system. … Titan is bigger than Earth’s moon, and larger than even the planet Mercury.
Is Titan bigger than Mars?
Saturn’s Titan has an atmosphere denser than Earth’s, yet Titan is a smaller body than Mars. … Titan’s surface temperature is also quite low, about 90 K. Therefore, the mass fractions of substances that can become atmospheric constituents are much larger on Titan than on Earth.
Is Pluto larger than the moon?
Pluto is smaller than Earth’s moon. This dwarf planet takes 248 Earth years to go around the sun. … Its largest moon is named Charon (KAIR-ən). Charon is about half the size of Pluto.
What is the biggest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
Can we breathe on Titan?
Another theoretically possible means to become airborne on Titan would be to use a hot air balloon-like vehicle filled with an Earth-like atmosphere at Earth-like temperatures (because oxygen is only slightly denser than nitrogen, the atmosphere in a habitat on Titan would be about one third as dense as the surrounding …
Is there gold on the moon?
There is water on the moon … along with a long list of other compounds, including, mercury, gold and silver. … Turns out the moon not only has water, but it’s wetter than some places on earth, such as the Sahara desert.
Is there gold in space?
As it turns out, there’s a giant asteroid that contains enough gold and other metals to make everyone on Earth a multibillionaire. And NASA uses gold to protect spacecraft from radiation. With all the gold out in space, extraterrestrial mining is a real possibility.
Can you land on Saturn?
As a gas giant, Saturn doesn’t have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn’t be able to fly through unscathed either.
Do any moons have magnetic fields?
Possessing a metallic core, it has the lowest moment of inertia factor of any solid body in the Solar System and is the only moon known to have a magnetic field. Outward from Jupiter, it is the seventh satellite and the third of the Galilean moons, the first group of objects discovered orbiting another planet.
Can we live on Ganymede?
In 1996, astronomers using the Hubble Space Telescope found evidence of a thin oxygen atmosphere. However, it is too thin to support life as we know it; it is unlikely that any living organisms inhabit Ganymede. … Ganymede’s magnetosphere is entirely embedded within the magnetosphere of Jupiter.
Can you survive on Mars without a spacesuit?
Mars is perhaps the only other potentially-habitable planet in our solar system, but you still couldn’t live there without a space suit. It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure.
Will humans live on Mars?
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. … Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.
What planets could we live on?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
