Incredible Facts About Jupiter
Jupiter’s moon Ganymede is the largest object in our solar system that has no substantial atmosphere.
In the core of Jupiter, it is hotter than on the solar surface.
Jupiter is the largest planet in our solar system. It is 11 times as big as Earth.
With 62 moons, Saturn has the second most after Jupiter. Jupiter hat 68 moons.
The gravitational pull of Jupiter is so strong that a rocket would have to travel 135,000 miles per hour (215,000 kilometers per hour) to leave the planet.
Uranus was the first planet discovered with the aid of a telescope as Mercury, Mars, Venus, Saturn, and Jupiter were all bright enough to be easily visible to the naked eye.
On Jupiter and Saturn it rains diamonds.
On Jupiter the days are shorter than on any other planet in our solar system. For a rotation around its own axis, the giant needs only ten hours.
Jupiter’s moon Ganymede is the largest moon in the solar system. With a diameter of 3,273 miles (5,268 kilometers) it is even larger than the planet Mercury.
On Jupiter’s moon Europa, there is probably an ocean under a thick layer of ice that holds more water than the oceans of the Earth combined. Scientists believe it may even contain microbes.
The “Great Red Spot” on Jupiter is a large high-pressure area twice the size of the Earth. It is the largest hurricane in the solar system and is believed to have existed for over 400 years.
It is not known where the “Great Red Spot” on Jupiter gets its red color from.
The four largest moons of Jupiter are also called Galilean moons, since Galileo Galilei was the first to describe them. He mentioned Ganymede, Callisto, Io and Europa already in 1610.
So far there have been eight space probes that have examined Jupiter.
While Saturn has long been known for its rings, the ring systems around the gas planets Jupiter, Uranus, and Neptune were first discovered in the 1970s.
Since Jupiter consists mostly of hydrogen and helium, the planet is sometimes called a fallen star, since these are the basic requirements for stellar fusion. But in fact, despite its size, it is not massive enough to start fusion processes in its interior. This would require about 70 times its mass.
Jupiter has the largest magnetic field in our solar system and therefore even surpasses that of the sun. One of the reasons for this is the high rotational speed of the planet.
Jupiter is named after the Roman king of the gods.
