The planet Jupiter is the fifth planet in the solar system. Jupiter is the largest planet in the solar system and contains two and a half times more mass than all the other planets in the solar system combined. It is made primarily of gases and is one of the gas giant planets. Here are some planet Jupiter facts.
What are some amazing facts about Jupiter?
1. Jupiter is the fourth brightest object in the Solar system after Sun, Moon, and Venus. Jupiter is one of five planets that can be seen with the naked eye from Earth.
2. The Average diameter of Jupiter is approximately 88,846 miles or 303918.18 Kms. Jupiter is so big that more than 1300 Earth could fit inside it.
3. Jupiter is named after the king of the Roman gods in mythology.
4. Jupiter has the shortest time of rotation among planets, thus Jupiter has the shortest day of all the planets. Jupiter rotates on its axis once every 9 hours and 55 minutes. The rotation is so fast that it flattens the planet slightly, giving it an oblate spheroid shape.
5. Jupiter completes one orbit around the Sun every 11.8 Earth years. If we see from Earth’s point of view, Jupiter seems to move slowly in the sky.
6. Jupiter is known for its large red spot which is actually a huge storm. The huge storm is so large that three Earths could fit inside it. The storm has been continuously observed for last 188 years. The storm on Jupiter was observed as early as 1665 but this is not sure if the storm observed then is the same red storm that we see today. If this is the same storm, then red spot has existed for about 350 years.
7. Jupiter has a ring system which was the third to be discovered in the Solar System, after Saturn and Uranus. It was first observed in 1979 by the Voyager 1 space probe. Jupiter’s ring system is composed of four main components:
A. a thick inner torus of particles – “halo ring”
B. A relatively bright and exceptionally thin “main ring”
C. Two wide, thick and faint outer “gossamer rings” named – Amalthea and Thebe.
8. Jupiter is a gas giant planet and does not have any solid surface. Its atmosphere is mainly made up of Hydrogen and Helium.
9. Jupiter has a total of 69 moons. 53 Moons have been officially named and 16 moons are yet to be named. The Galilean moons are the four largest and prominent moons of Jupiter. They were first observed by Galileo Galilei in January 1610 and thus named after him. The Galilean moons of Jupiter are – Ganymede, Europa, Io, Callisto. Jupiter’s moon Ganymede is the largest moon in the solar system. Ganymede is larger than the planet Mercury with a diameter of around 5,268 km.
10. Jupiter has a very strong magnetic field which is the largest of all planets in the solar system. The magnetic field on Jupiter is around 14 times stronger than the magnetic field found on Earth.
11. Jupiter has more than 317 times the mass of the Earth, providing its huge gravity. The Gravity on Jupiter is 24.79 m/s² which is about 2.5 times the Gravity of Earth. Your weight on Jupiter will be 2.5 times the weight on Earth.
12. Jupiter does not experience various seasons like other planets such as Earth and Mars. This is because the axis of Jupiter is tilted at only 3.13 degrees. Seasons change more slowly on Jupiter because of its distance from the sun and, duration of orbit around the Sun. The length of each season is roughly three years.
13. Nine spacecraft have visited Jupiter so far. The first spacecraft to visit Jupiter was Pioneer 10 in 1973. Juno is the latest spacecraft to visit Jupiter. Juno entered the polar orbit of Jupiter on July 5, 2016, to begin a scientific investigation of the planet. There are also plans for future missions to focus on the Galilean moons of Jupiter and their possible subsurface oceans.
14. Jupiter’s interior is made of rock, metal, and hydrogen compounds. There are layers of compressed hydrogen gas, liquid metallic hydrogen, and a core of ice, rock, and metals below Jupiter’s massive atmosphere. The upper atmosphere of Jupiter is divided into cloud belts and zones.
