What is Jupiter’s biggest moon called?
What are the names of Jupiter’s 79 moons?
The groups of Jupiter’s moons
- Inner moons. These are the moons which orbit closest to Jupiter and they are sometimes known as the Amalthea group.
- Galilean moons. The largest four moons of Jupiter – Io, Europa, Ganymede and Callisto – were discovered by Galileo in 1610 and are known as the Galilean moons.
- Outer moons.
Which of the Galilean moons is most geologically active Why?
With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean satellites—Europa, Ganymede and Callisto.
What are the largest moons in the solar system?
Biggest Moons In Our Solar System
- Ganymede. Ganymede is the largest of Jupiter’s 79 moons as well as by far the largest moon in the solar system.
- Titan. Titan orbits Saturn and is the second largest moon with a diameter of 5,150 km.
- Other Large Moons.
Are Jupiter’s moons bigger than Earth?
However, not all of the moons are smaller than all of the planets. There are seven moons in our Solar System, including our own Moon, that are larger than Pluto. 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.
How many times Jupiter is heavier than Earth?
Just to give you a sense of scale, Jupiter is 2.5 times more massive than all the rest of the planets in the Solar System combined. Jupiter’s diameter is 11.2 times larger than Earth. In other words, you could put 11.2 Earths side-by-side to match the diameter of Jupiter. And Jupiter’s volume is even bigger.
What are the names of Jupiter’s four largest moons?
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.
Which of Jupiter’s moons can support life?
In the Solar System
|Europa||Jupiter||Life on Europa|
|Enceladus||Saturn||Enceladus – potential habitability|
|Titan||Saturn||Life on Titan|
|Callisto||Jupiter||Callisto – potential habitability|

How many moons does Jupiter have NASA?
With four large moons and many smaller moons, Jupiter forms a kind of miniature solar system. Jupiter has 79 confirmed moons. Jupiter’s four largest moons—Io, Europa, Ganymede and Callisto—were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope.
Why is Jupiter moon named Io?
Io was the first of Jupiter’s moons discovered by Galileo Galilei on Jan. 8, 1610. Galileo’s discovery eventually led to the understanding that planets orbit the sun, instead of our solar system revolving around Earth. Galileo first referred to this moon as Jupiter I. In the mid-1800s, the moon was renamed Io.
How big is Europa vs Earth?
It takes Europa three and a half Earth-days to orbit Jupiter. Europa is tidally locked, so the same side faces Jupiter at all times. Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth’s moon, but larger than Pluto. It is the smallest of the Galilean moons.
Which of the Galilean moons are geologically active?
Even though Io has nearly the same size (3643 km across) and density (3.53X water) as the Moon, Io is the most geologically active world in the solar system. Io has many volcanoes and all of its craters are volcanic in origin.
What planets are larger than Earth?
The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.
Is the moon bigger than Earth?
The Moon is exceptionally large relative to Earth: Its diameter is more than a quarter and its mass is 1/81 of Earth’s. 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.
Which planet has the largest volcano?
Is Jupiter bigger than the sun?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
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 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 is the size of Jupiter?
What is the gravity on Jupiter?
Who is Jupiter?
Jupiter (Latin: Iuppiter) is the king of the gods in Roman mythology. He was the god of the sky and thunder. He is known as Zeus in Greek mythology. His brother’s name was Pluto and his sister was Ceres.
How many moons does Jupiter have Wikipedia?
Does Mars have rings?
It is also predicted that Phobos, a moon of Mars, will break up and form into a planetary ring in about 50 million years, because its low orbit with an orbital period that is shorter than a Martian day is decaying due to tidal deceleration.
Who discovered Jupiter’s rings?
How did Jupiter get its red spot?
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.
What color is the sky on Mars?
The normal hue of the sky during the daytime is a pinkish-red; however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown “butterscotch” color. On Mars, Rayleigh scattering is usually a very small effect.
How many atmospheric layers are there?
In this way, Earth’s atmosphere can be divided (called atmospheric stratification) into five main layers. Excluding the exosphere, the atmosphere has four primary layers, which are the troposphere, stratosphere, mesosphere, and thermosphere.
