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 planets have large moons?
Jupiter’s moon Ganymede is the largest moon in the Solar System, and Ganymede as well as Saturn’s moon Titan are both larger than Mercury and Pluto. Earth’s Moon, Jupiter’s moons Callisto, Io, and Europa, and Neptune’s moon Triton are all larger than Pluto, but smaller than Mercury.
Is Earth’s moon the biggest?
It is the largest moon in the Solar System relative to the size of its planet, though Charon is larger relative to the dwarf planet Pluto, at 1/9 Pluto’s mass. The Earth and the Moon’s barycentre, their common centre of mass, is located 1,700 km (1,100 mi) (about a quarter of Earth’s radius) beneath Earth’s surface.
Which planet has largest natural satellite?
Most of the 194 known natural satellites of the planets and dwarf planets are irregular moons, while only 19 are large enough to be round. Ganymede, followed by Titan, Callisto, Io and Earth’s Moon are the largest natural satellites in the Solar System (see List of natural satellites § List).
How many moons does Jupiter have in 2018?
The number of moons known for each of the four outer planets up to July 2018. Jupiter currently has 79 known satellites.
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.
Does any planet have water?
Using such methods, many scientists infer that liquid water once covered large areas of Mars and Venus. Water is thought to exist as liquid beneath the surface of some planetary bodies, similar to groundwater on Earth.
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|

Which planet has the largest volcano?
Is Pluto smaller than the Earth’s moon?
With less than 0.2 lunar masses, Pluto is much less massive than the terrestrial planets, and also less massive than seven moons: Ganymede, Titan, Callisto, Io, the Moon, Europa, and Triton. The mass is much less than thought before Charon was discovered.
Is Ceres bigger than the moon?
It was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was still more than ten times as massive as the largest object in the asteroid belt, Ceres, it had one-fifth the mass of Earth’s Moon.
Does Earth have any rings?
A ring system around a planet is also known as a planetary ring system. The most prominent and most famous planetary rings in the Solar System are those around Saturn, but the other three giant planets (Jupiter, Uranus, and Neptune) also have ring systems.
Which planet has a moon called Larissa?
Does the moon affect the Earth rotation?
Tidal locking results in the Moon rotating about its axis in about the same time it takes to orbit Earth. Except for libration effects, this results in the Moon keeping the same face turned toward Earth, as seen in the left figure. (The Moon is shown in polar view, and is not drawn to scale.)
Is Earth a satellite of sun?
As it orbits the Sun, 2016 HO3 appears to circle around Earth as well. It is too distant to be a true satellite of Earth, but is the best and most stable example of a quasi-satellite, a type of near-Earth object.
Is the Earth slowing down on its axis?
Earth’s rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth’s rotation. Atomic clocks show that a modern day is longer by about 1.7 milliseconds than a century ago, slowly increasing the rate at which UTC is adjusted by leap seconds.
How many satellite does the earth have?
Currently there are approximately 1,886 artificial satellites orbiting the Earth. Heliocentric orbit: An orbit around the Sun. In our Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris.
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.
What are the 4 moons of Jupiter?
The Galilean moons are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610.
How many sub planets does Jupiter have?
Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has 79 known moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury.
How many planets can support life?
In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be orbiting Sun-like stars.
Can life support Mars?
The confirmation that liquid water once flowed on Mars, the existence of nutrients, and the previous discovery of a past magnetic field that protected the planet from cosmic and solar radiation, together strongly suggest that Mars could have had the environmental factors to support life.
Is Titan habitable for humans?
Saturn’s largest moon Titan is one of several candidates for possible future colonization of the outer Solar System. According to Cassini data from 2008, Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth.
