20 Incredibly Fascinating Facts About Jupiter No One Ever Told You

Fact about Jupiter
Jupiter, known as the king of planets, is the largest planet in the solar system. Here are some more interesting facts about this great gas giant.
Jupiter is a massive planet, bigger than all the other planets combined together. It is the fifth planet in the solar system, and the fourth brightest object present in the sky. It is named after the king of a Roman God, also known as Zeus in Greece. Most of Jupiter's satellites got their names from King Zeus's daughters and lovers. Jupiter is also known as a planet of luck, and has great astrological significance.
Common Facts
~ The diameter of the planet Jupiter is 88,846 miles, which means it is more than 11 times that of Earth.

~ The total mass of Jupiter is 1.9 x 1027 kg, which is almost 318 times the mass of Earth.

~ The temperature in the clouds of Jupiter is about -234 degrees Fahrenheit.

~ But its core is estimated to have a temperature of about 43,000 degrees Fahrenheit.

~ One year on this planet is equivalent to around 12 years on Earth.
~ It rotates extremely fast, taking only 9 hours 55 minutes for one rotation around itself. This planet has the shortest day as compared to any other planets in the Solar System.

~ Jupiter has 63 moons known so far.

~ The density of Jupiter is 1.326 g/cm³ which is about ¼ of the Earth's density.

~ Jupiter has an intense and powerful magnetic field around itself known as the magnetosphere.

~ The atmosphere of Jupiter is very stormy, consisting of intense wind patterns.
Other Facts About Jupiter
~ Jupiter being so massive, exerts an intense gravitational pull on all the things around it. This enormous gravitational pull attracts comets and other rocky substances towards its atmosphere, and so Jupiter is also called the 'vacuum cleaner' of the Solar System.
~ Jupiter is an enormous planet. But if it continues to get more massive, it would start shrinking. Any additional mass on Jupiter will make it even more denser, pulling the mass towards itself. This will decrease the overall size of Jupiter even though its mass continues to increase.
~ Unlike other planets, Jupiter is not composed of mass and matter. It is an enormous ball of gases like hydrogen, helium and nitrogen. It has very little solid surface. The atmosphere is so dense on Jupiter, that it appears like a solid body.
~ Jupiter is an angry planet with a stormy surface. The Great Red Spot is a giant storm which is known to have existed on Jupiter for hundreds of years. It keeps moving in an anticlockwise direction and is known to bear the coldest spot on Jupiter.
~ Similar to the planet Saturn, Jupiter too has rings around it, though they are much fainter than Saturn's. They are probably the materials ejected by Jupiter's moons when they are struck by meteorites.
~ Jupiter emits electromagnetic sounds which were first recorded by the NASA's voyager.
Moons of Jupiter
~ The first scientist to observe Jupiter's moons was Galileo Galilei. He discovered the four largest moons of Jupiter namely, Callisto, Ganymede, Europa and Io, also known as Galilean moons. Ganymede is the largest moon in the Solar System, and is even larger than the planet Mercury.
~ Callisto is farthest from Jupiter among the Galilean moons. It has the most cratered surface compared to any other moon in the Solar System, and is made up of ice, water and rock. Io is the moon closest to Jupiter and has about 80 volcanoes. It is bigger than the Earth's moon.
~ Europa, the smallest of the four, appears to have a smooth and bright surface. It is the most mysterious of all and has fascinated scientists for long. Apart from these four moons of Jupiter, scientists have discovered many smaller satellites, which makes the total 63, till date.
~ Jupiter has a lot of activity happening on its surface and in its atmosphere. It is really a sight to watch this planet through a telescope. You can also see Jupiter with the naked eyes, as it is one of the brightest objects in the sky.
