What are the names of the big planets, and which one is the biggest?

The so-called "nine planets" of the solar system are an outdated term that has been popular throughout history, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. In Resolution 5 adopted at the 26th International Astronomical Union held in Prague on 24 August 2006, Pluto was classified as a dwarf planet and named Asteroid 134340, removing it from the nine planets of the solar system. So now there are only eight planets in the solar system.

That is, as of August 24, 2006, there are only 8 planets in the solar system, namely: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Jupiter is the fifth planet from the Sun and the largest.

Fang Cheng, academician of the Chinese Academy of Sciences, vice chairman of the International Astronomical Union, and professor of Nanjing University, said in an interview with the reporter of the "International Herald Leader" that in short, the planets are divided into three categories, namely "classical planets", "dwarf planets" and "small celestial bodies of the solar system". Dr. Zhu Jin, director of the Beijing Planetarium and a well-known asteroid expert in China, told this reporter that the decision is to expel Pluto from the nine planets. According to General Assembly Resolution 5, Pluto's planetary status will still be maintained, but it has been downgraded from a large planet to a second-class planet - a "dwarf planet".

At the same time, three celestial bodies will be promoted to second-order planets: the largest asteroid Ceres, Pluto's largest moon Charon, and 2003UB313 (Zena), discovered in 2003. In this way, the number of planets in the solar system increased from 9 to 12.

Eight of them are classical planets (commonly known as big planets), which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, while there are four secondary planets "dwarf planets", which are Pluto, Charon, Ceres, and Xena. According to experts, Pluto and its moon Charon meet the new definition of planets, with a diameter of 2:1, the center of gravity is not in Pluto, and their movement is like a ballroom dance in the sky.

In this way, they will probably be the first confirmed double planets in the solar system.

Eight planets. They are called Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was expelled from the ranks of the planets due to its small size, etc.

The largest is Jupiter.

The largest planet is: Jupiter.

Jupiter is the solar system.

The fifth planet is the largest of the nine planets.

Jupiter is about 10,000 kilometers in diameter, twice the diameter of the Earth, 1,316 times the volume of the Earth, and twice the mass of all the other planets combined.

It orbits the Sun for about 12 years, while it rotates in less than 10 hours. Because it rotates so fast, the star is flattened, and the equatorial radius differs from the polar radius by as much as 5,000 kilometers. Jupiter has a solid core with a diameter of 24,000 kilometers inside, and the core of Jupiter is hot, possibly up to 20,000 degrees.

Outside the nucleus is metallic hydrogen and helium, which are about 50,000 kilometers thick. Beyond that are the "oceans" of liquid hydrogen and helium, and ammonia and methane.

composition of the surface atmosphere.

Jupiter has 16 moons, the four largest of which are Ganymede.

One, two, three, four. They were created in 1610 by Galileo.

discovered, so they are also called Galileo satellites. They are all special objects in the solar system. There are active volcanoes on Europa, liquid water on Europa, and perhaps life.

What should be said is the largest planet in the solar system? That's Jupiter. Because the planets in the universe do not emit light on their own, it is difficult for us on Earth to see planets outside the solar system.

The largest planet in the world is Jupiter.

Jupiter is the largest of the eight planets in the solar system, with an extremely large mass, more than twice that of the other seven planets combined, 318 times that of Earth, and 1,321 times the volume of Earth. At the same time, Jupiter is also the fastest rotating planet in the solar system, so Jupiter is not positively spherical, but the poles are slightly flattened and the equator is slightly bulging.

Jupiter is the fourth brightest star in the sky, after the Sun, the Moon, and Venus (sometimes it is slightly fainter than Mars, but sometimes it is brighter than Venus). Jupiter is mostly composed of hydrogen and helium, and its central temperature is estimated to be as high as 30,500. Jupiter has a large red spot on its surface, located south of Jupiter's equator.

From east to west, the longest is 48,000 kilometers, and the smallest is more than 20,000 kilometers; From north to south, it is 14,000 kilometers at its longest and 11,000 kilometers at its shortest, covering an area of about 453,250,000 square kilometers, which can accommodate three earths.

There is still debate about what it is, and many believe that it is a never-ending whirlwind, the Great Red Spot, discovered in 1665 by the astronomer Cassini of French descent, which rotates in a counterclockwise direction every 6 Earth days, often rolling up cloud towers up to 8 kilometers high. It changes color and shape from time to time, but it never disappears completely.

1. Jupiter. 2. It has become the king of the nine stars because of its huge (volume and mass). It is the brightest star in the sky after Venus, and is usually brighter than Mars and Sirius.

3. The volume is 1316 times that of the earth. The mass is grams, which is times the mass of the Earth and is heavier than all the planets, moons, asteroids and other large and small celestial bodies in the solar system combined. The average density of Jupiter is grams centimeters , which is slightly larger than water.

This means that most of Jupiter's matter is in a gaseous state.

The largest planet in the solar system is Jupiter.

Jupiter is the largest and fastest rotating in the solar system, with a mass of one-thousandth the mass of the Sun and twice the mass of the other seven planets in the solar system combined. Since Jupiter, Saturn, Uranus, and Neptune are all gas planets, they are also called Jupiter-like.

Jupiter is oblate spheroids (with a slight but visible bulge near the equator) due to its rapid rotation (10 hours per rotation), and the outer atmosphere is clearly divided into zones according to latitude, and the margins where each zone is connected are prone to turbulence and storms, most notably the Great Red Spot. The planets are surrounded by a weak system of planetary rings and a powerful magnetosphere (Jupiter's magnetic field is so strong that it extends to Saturn's orbit with its back to the Sun).

Jupiter, known since ancient times, is easy to see at night with the naked eye and occasionally during the day when the Sun is low. In Babylon, this celestial body represents their god Marduk. They use Jupiter's orbit around the ecliptic for about 12 years to define their zodiac's house of stars.

The Romans mythologically named Jupiter (Latin: iuppiter, iūpiter, also known as jova), the main god in Roman mythology, whose name comes from the Proto-Indo-European Hugh composite *dyēu-p ter (nominative case: *dyēus-p tēr, meaning "o Father of the Celestials" or "Father of the O Celestials").

Comparatively, Jupiter corresponds to Greek mythology and is the name of Zeus ( also known as Dias (δ in which the names of the planets are still preserved in modern Greek. In English, Thursday (Thursday) is derived from "Thor's Day" (Thor).'s day), which is out of Germanic mythology. Compared to Roman mythology is Jupiter.

The Jovis of Roman Thursday was also renamed Thursday.
