Why is Jupiter known as the Little Solar System ?

In 1610, the Italian astronomer Galileo Galilei discovered Iode with a homemade telescope.

1. Ganymede. 2. Europa and Europa. Later these 4 satellites became known as Galileo satellites.

All four Galilean moons are more massive than Pluto, with Europa being the largest moon in the solar system, larger than Mercury. Inside the orbit of the 4 Galilean moons, there are 4 more moons of Jupiter, which are Ganymede.

Ten. Sixth, Ganymede.

5. Europa, of which Calmede is the closest moon to Jupiter.

Jupiter has 4 large moons, of which Europa is the largest in the solar system, it is much larger than the Moon and even larger than the planets Pluto and Mercury. The rest of the Ganymede.

1. Ganymede. 2. Ganymede is also among the top seven moons of the solar system (the other three are Enceladus.)

6. The Moon and Triton). These four large moons were discovered by Galileo in the 17th century, so they are also called "Galileo Moons", and they all have solid surfaces that can become relay stations for space navigation. The four moons, like the planets of the solar system, are less dense the farther away they are.

In addition to the four major satellites, there are 13 smaller satellites. Jupiter, with its 17 moons, is self-contained, like a "small solar system".

Satisfied, thank you

Jupiter is the largest and fastest-rotating planet in the solar system and the fifth planet aligned from the inside out. Jupiter is the largest planet in the solar system, with a mass of one-thousandth the Sun. Jupiter, along with Saturn, Uranus, and Neptune, are all gas planets.

On February 23, 2012, scientists discovered two new moons of Jupiter. Jupiter's central temperature is estimated to be as high as high and consists of 86% hydrogen and 14% helium. Jupiter is the largest of the eight planets in the solar system, with a mass twice that of Earth and 1,316 times the volume of Earth.

Ancient China called it Sui Xing or Tai Sui, and modern people call Jupiter the solar year because Jupiter's age is only one-thirteen of the Earth's age. Italian astronomer Galileo Galilei discovered Ganymede.

II. Europa and Europa, and named them Europa. Ilymede.

IX, XXVII and XXVIII. From the Galileo moons to Ganymede.

Ten. 3. The distance between Ganymede and Ganymede is: Ilymede.

4. The reverse rotation period of Ganymede and Ganymede is about 700 days, respectively. Jupiter is surrounded by so many moons, it's no wonder it has"Small solar system"Such a reputation.

Jupiter is a planet in the small solar system and the largest planet in the entire solar system. This fact is widely recognized and has many evidences. One of them is the mass and volume of Jupiter.

Jupiter is the largest in the solar system except for the Sun, and it is also the largest in the solar system, surpassing the other seven planets combined. This makes Jupiter's gravitational pull on other planets very strong and affects the stability of the entire solar system.

Another piece of evidence is the number of moons of Jupiter. Jupiter has at least 79 known moons, the most of any planet. While these moons orbit Jupiter, they also affect the entire planetary system.

For example, when planets such as Venus, Earth, and Mars approach Jupiter, they are subjected to the gravitational pull of the planets, creating small orbital perturbations.

Finally, the strength of Jupiter's magnetic field is also one of the bases that proves that it is a small solar system. Jupiter's magnetic field is the second largest in the solar system, second only to the Sun. This powerful magnetic field produces energy large enough to affect other planets and moons, and may affect the magnetic activity of the Sun.

To sum up, Jupiter, as a planet of the small solar system, has many pieces of evidence. Jupiter's mass, size, number of moons, and magnetic field strength are all evidence supporting its impact on the solar system. These properties make it one of the most important celestial bodies for studying the solar system and planetary motion.

Jupiter has helped the Earth withstand 21 waves of annihilation, and in the past two months, Jupiter has been hit twice in succession. There's a reason why Jupiter and Earth collided instead of Mars. In 1994, Jupiter was hit by 21 consecutive waves of interstellar impacts, each of which would be enough to wipe out humanity if it were put on Earth, which was the first celestial impact event observed by a planet in the solar system.

Jupiter's orbit

Jupiter's common center of mass with the Sun is actually located outside the radius of the Sun at a time of the Sun's center – or 7% of the Sun's radius beyond the Sun's surface. The average distance from Jupiter to the Sun is 778 million kilometers (about times the distance from the Earth to the Sun, or astronomical units), and it takes Earth years to revolve the Sun in one revolution. This is two-fifths of Saturn's orbital period, which means the formation of 5:5 between the two largest planets in the solar system

The resonance orbital period of 2 is quietly in the reed.

Jupiter's elliptical orbit is tilted relative to the Earth's orbit because of the eccentricity, so the distance between perihelion and aphelion is 75 million kilometers. Jupiter's axis inclination is very small compared to Earth and Mars, only, so there are no significant seasonal variations.

Jupiter's rotation is the fastest of all the planets in the solar system, and it takes less than 10 hours to complete a rotation of its axis; This causes an equatorial uplift that can be easily seen on Earth with a small amateur telescope. The planet is an oblate sphere, meaning that its equatorial diameter is longer than the diameter between the poles.

Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, the fifth planet from the inside out. It has a mass of one-thousandth the mass of the Sun and a mass of the other seven planets in the Solar System combined. Jupiter, Saturn, Uranus, and Neptune are all gas planets, so they are also called Jupiter-like planets (Jupiter and Saturn are collectively called gas giants).

Jupiter is a gas giant that makes up 70% of all the planets in the solar system and is mainly composed of hydrogen, followed by helium at 25% of the total mass, and the core contains other heavier elements. What humans see is usually the tip of the clouds in the atmosphere, with a slightly higher pressure than 1 atmosphere.

Jupiter is a giant liquid hydrogen planetary body. As the depth increases, at kilometers above the surface, liquid hydrogen forms at high pressures and temperatures. It is speculated that the center of Jupiter is a core region composed of silicate and iron and other perforated substances, and the composition of the material is in a continuous transition from density.

Jupiter may be huge, but it spins faster than any other planet. Spin at nearly 30,000 miles per hour! Because of this speed, Jupiter's day is only 10 hours!

This incredible speed of the manuscript has even led to a significant expansion of the region near Jupiter's equator.

Jupiter's most famous feature, the Great Red Dot is a wild and huge storm. The storm is large enough to hold three diameter Earths with honorifics. The Big Red Dot is over 350 years old and shows little sign of slowing down at any point!

According to the observations, scientists have found that the most pronounced red region in Jupiter's Great Red Spot confirms the theory that there is a hot core inside the cold storm system. The dark lines at the edge of the storm in the observation show that the gas released by the storm eruption is spreading into the interior of the planet.

The temperature of Jupiter's inner center is as high as 280,000 K, which has reached the temperature required for thermonuclear reactions, but the pressure of Jupiter's internal center has not yet reached the requirements of thermonuclear reactions. According to scientists, the pressure in Jupiter's inner center has been rising for several years, and after billions of years, the pressure in Jupiter's inner center may be able to meet the requirements for thermonuclear reactions. At that time, Jupiter, which has the basic conditions for thermonuclear reactions, will change its internal heat production capacity from the original way to nuclear fusion, and the vortex rotating atmosphere is a huge "emitter" of energy generated by nuclear fusion inside Jupiter, constantly releasing energy to the outside world.

As a result, scientists speculate that in a few billion years, Jupiter may be "transformed" from a planet to a star.

Fixed star.

The sun is the central celestial body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way. The Sun is a star located at the center of the solar system, and it is almost an ideal sphere with hot plasma intertwined with a magnetic field.

The diameter of the Sun is about 1,392,000 kilometers (109 times the diameter of the Earth; It is about 1.3 million times the size of the Earth; Its mass is about 2 10 kilograms (330,000 times that of the Earth). In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% of the mass, which uses nuclear fusion to release light and heat into space.
