What are the 4 satellites of Jupiter?
The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds.
What are the 16 satellites of Jupiter?
Jupiter’s 16 known moons conveniently divide into four quartets according to their orbits, listed in Table J2, and their physical characteristics, given in Table J3….Jupiter: Satellite system.

Is there a satellite orbiting Jupiter?
The probe completed a tricky maneuver on July 4 to settle into a long orbit around the giant planet and begin to unlock its mysteries.
What are the 4 major Galilean satellites of Jupiter?
Galilean moons. In January 1610, Italian astronomer Galileo Galilei discovered four of Jupiter’s moons — now called Io, Europa, Ganymede and Callisto.
How many moons does Jupiter have 2021?
53
Jupiter has 53 named moons and another 26 awaiting official names.
What are Jupiter’s 53 named moons?
Jupiter has 53 named moons, including the four largest—Ganymede, Io, Callisto, and Europa—which were discovered by Galileo Galilei back in 1610. Sixteen others still don’t have names, including two moons that were identified last year, bringing the total at that point up to 69.
Is Juno still orbiting Jupiter?
Juno mission extended to 2025 Now Jupiter’s strong gravity has reduced Juno’s orbit to 43 days. The Juno mission was originally scheduled to end in July 2021. But in January of this year, NASA extended the mission. Juno will now continue exploring Jupiter through September 2025, or until the spacecraft’s end of life.
Can humans land Jupiter?
The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn’t be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt, and vaporize spacecraft trying to fly into the planet.
How many satellites are there in Jupiter?
Jupiter has 53 named moons and another 26 awaiting official names. Combined, scientists now think Jupiter has 79 moons.
What are the 4 large moons?
67 moons orbit the great gas giant Jupiter; of these, the four largest are known as the Galilean moons, having been discovered by Galileo Galilei using his telescope in 1610. The four moons are Io, Europa, Ganymede, and Callisto, in order of distance from Jupiter.
Where can I find more information about Jupiter?

What is Juno doing on Jupiter?
The Juno spacecraft, which successfully entered the orbit of Jupiter on July 4, 2016, will for the first time peer below the dense cover of clouds to answer questions about the gas giant and the origins of our solar system. Loading…
Is Callisto on Jupiter’s moon Ganymede?
This view of Jupiter’s moon Ganymede shows the stark contrast between the smooth bright terrain and highly fractured dark terrain. Callisto was revealed by the Voyager cameras to be a heavily cratered and hence geologically inactive world.
