Jupiter is the 5-th planet and first gas giant from the sun in our solar System. It is 11 times the diameter of Earth and almost 2.5 times the combined mass of the other seven planets of the Solar System.
Its vast globe has a distinctively banded atmosphere that is affected by storms and winds of up to 388 mph (625 kph), and its immense gravity has meant it has clung on to or captured a huge collection of moons respectively 62.
Jupiter orbits the sun every 12 Earth years, and its axis every 10 hours, so the axis speed is more than 2 times bigger than that of Earth, and that is why the equatorial region is 6.5 percent wider. Jupiter’s axis is tilted at only 3° tilted, which means that the planet has no seasons, because neither hemisphere is significantly tilted towards the Sun.
At Jupiter’s center there is thought to be a dense core with a mass several times that of Earth. The core is surrounded by a layer if liquid metallic hydrogen, which, in turn, is surrounded by a layer of liquid hydrogen and helium. The atmosphere is mostly of hydrogen, helium and other trace gases. The high quantities in its atmosphere suggest that Jupiter is a failed star.
The biggest moons of Jupiter aka the Galilean Moons, were first discovered by Galilor Galilei in January 1610 and they are: Io, Callisto, Ganymede and Europa, Ganymede being the biggest one.
Europa, Ganymede and Callisto could have liquid water on them, as NASA stated in a conference.
We at Space Learning Web crated a slideshow with all ocean worlds in our solar system, including the three moons of Jupiter. Check the link below for more information:
There is a misterious giant storm on Jupiter three times bigger than Earth, raging on the planet for at least 350 years
The information and the photos were sent by the Voyager 1 & 2, when they did a flyby on their jurney to interstellar medium, and by the Juno spacecraft, which studies Jupiter since 2012.
Jupiter is a giant beautiful monster planet, which will be studied in the future by Juno and other space probes that will be sent to study its icy gallilean moons!
