One of Jupiter’s moons, Ganymede, is the largest moon in the Solar System.
Ganymede has a diameter of 3270 miles (5,268 km) and is larger than the planet Mercury.
It has a rocky core with a water/ice mantle and a crust of rock and ice.
Which is bigger Titan or Ganymede?
Frequently described as a planet-like moon, Titan is 50% larger 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. Titan is primarily composed of ice and rocky material.
Which planet has highest number of satellite?
How big is Ganymede compared to the Earth?
If Ganymede were orbiting the Sun it would be a planet. Ganymede is larger than both Mercury and Pluto, and is 2/3 the size of Mars with a diameter of 5,268 km (3,273 miles) – 8% larger than Mercury. It has the highest mass of all planetary satellites and has more than twice the mass of the Earth’s Moon.
Does Ganymede have life?
Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. Ganymede is composed of approximately equal amounts of silicate rock and water ice.
Can you live on Europa?
FULL STORY: What Would It Be Like to Live on Europa? Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.
Which planet do not have any moon?
The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them. Figuring out why is one question keeping astronomers busy as they study the Solar System.
What planet has the moon Titan?
Titan is Saturn’s largest moon and the second largest in the solar system (after Ganymede of Jupiter). It is the only moon in the solar system with clouds and a dense, planet-like atmosphere.
What planet has the most moons 2019?
Let’s go in order from the Sun.
- Mercury and Venus. Up first are Mercury and Venus.
- Earth (That’s us!) Up next is Earth, and of course we have one moon.
- Mars. Mars has two moons.
- Jupiter. Next are the giant outer planets.
- Saturn. Saturn has 53 moons that have been named.
- Uranus and Neptune.
Which moon is most habitable?
In the Solar System
|Enceladus||Saturn||Enceladus – potential habitability|
|Titan||Saturn||Life on Titan|
|Callisto||Jupiter||Callisto – potential habitability|
|Ganymede||Jupiter||Ganymede – Subsurface oceans|

Can you survive on Titan?
How Humans Could Live on Saturn’s Moon Titan (Infographic) Titan, the cloudy moon of Saturn, is one of the least hostile places (for humans) in the outer solar system. It has lakes of liquid methane, and even weather. Titan has no water, but some scientists wonder if life based on methane might live on Titan.
Can a moon have moons?
The results vary — the bigger the moon, for example, the closer it can be to the planet. In a few cases, however, there is a confluence of moon size and orbit in which a submoon could survive. Four moons in our solar system qualify: Earth’s moon; Jupiter’s moon Callisto; and two of Saturn’s moons, Iapetus and Titan.
Could Europa have life?
So far, there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth’s deep-ocean hydrothermal vents.
Can moons have water?
Lunar water is water that is present on the Moon. Liquid water cannot persist at the Moon’s surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space.
Is there any water in Jupiter?
This depth, in addition to the levels of carbon monoxide researchers detected on Jupiter, appears to confirm that Jupiter is rich in oxygen and, because its abundance of hydrogen is already well-known, has the ingredients for water.
Can humans live on Venus?
Habitability of its atmosphere. Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.
Can we live on Jupiter moon Europa?
Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. Europa’s geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.
Can a human survive on Uranus?
As an ice giant, Uranus doesn’t have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn’t be able to fly through its atmosphere unscathed either. The extreme pressures and temperatures would destroy a metal spacecraft.
Is Moon a planet or satellite?
The Moon, also known as Luna, is an astronomical body that orbits planet Earth and is Earth’s only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).
Does Earth have other moons?
Although the Moon is Earth’s only natural satellite, there are a number of near-Earth objects (NEOs) with orbits that are in resonance with Earth. These have been called, inaccurately, “second”, “third” or “other” moons of Earth.
How many moons does Pluto have 2018?
Has anything landed on Jupiter?
The first spacecraft to orbit Jupiter was the Galileo orbiter, which went into orbit around Jupiter on December 7, 1995. It orbited the planet for over seven years, making 35 orbits before it was destroyed during a controlled impact with Jupiter on September 21, 2003.
What is the eye on Jupiter?
The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anticyclonic storm, the largest in the Solar System, 22 degrees south of the planet’s equator. It has been continuously observed since 1830.
Does Jupiter have an atmosphere?
The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.
