Mercury, Venus, Earth, Mars, Jupiter, Saturn, Sky, Neptune Pluto has recently been expelled because it simply doesn't meet planetary standards...Thank you.

Is it a terrestrial planet?
Water, metal, Earth, Mars.
Jupiter and Saturn are called giant planets.
Uranus, Neptune is the planet of the Distant Sun.
This answer is correct.
-
Mercury, Venus, Earth, Mars.
-
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
They are arranged by distance from the sun.
But it seems that there is talk of a new planetary discovery.

Water, gold, earth, fire, wood, earth, king, sea king.
Hades is now called an asteroid.

The solar system consists mainly of nine planets revolving around the Sun: Venus, Jupiter, Mercury, Mars, Saturn, Earth, Pluto, Uranus, and Neptune. More than 50 moons orbiting different planets, tens of thousands of asteroids, comets, meteoroids, and interplanetary gas and dust matter.
-
Water, metal, earth, fire, small, wood, earth, heaven, sea, underworld.
It's pretty smooth.
-
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Sky, Neptune.
-
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Sky, Neptune, Pluto are nine planets.
They are arranged according to their distance from the sun.

It's a terrestrial planet.
Mercury, Venus, Earth and Mars.

Question 1: Why is the Earth an ordinary planet in the solar system Because it has the same constituent elements as other planets, it rotates in the same direction, neither the largest nor the smallest, and is neither the closest nor the farthest from the sun.
Question 2: The difference between the earth and other planets The difference between the earth and other planets is mainly reflected in the fact that the earth is the only celestial body in the universe where life is known to exist, and it is home to millions of creatures, including human beings.
Earth is one of the eight planets in the solar system, the third planet in order of being disturbed from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun. [1]
It has a natural satellite of the Moon, and the two make up a celestial system, the Earth-Moon System. 4.6 billion years ago, filial piety originated in the primordial solar nebula.
The radius of the Earth's equator is kilometers, the polar radius is kilometers, the average radius is about 6,371 kilometers, and the circumference of the equator is about 40,076 kilometers. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land. The interior of the earth has a core, mantle, and crust structure, and the outside of the earth has a hydrosphere, atmosphere, and magnetic field.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
The first four belong to terrestrial planets, which are small, dense, and solid, while the last four belong to Jupiteroids, which are large, dense, and gaseous. Based on the farthest orbital radius of Neptune, the eight planets, as well as the Sun, are distributed within a nearcircular range with a radius of about 30 celestial dust or literary units.
Pluto, once considered one of the "Nine Planets", was defined as a "dwarf planet" on August 24, 2006. In addition, there are many smaller planets in the solar system in the asteroid belt between Mars and Jupiter, as well as the Oort Nebula, which extends nearly a light-year away from the Kuiper belt, all of which belong to the range of the solar system, and Jupiter has the most moons among the eight planets, and Jupiter has been found to have 68 moons.

The solar system has 1 star, 8 planets, 4 dwarf planets, 5 asteroids, 82 moons, and more than 5 periodic comets.
The Sun is the only star and luminous object in the solar system and is the central object of the solar system. There are only eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The planets of the Solar System, 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, which was removed from the nine planets of the Solar System.
So now there are only eight large planets in the solar system. That is to say, from August 24, 2006 11, there are only 8 planets in the solar system, namely: Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Uranus.
There are eight planets in the solar system. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. In addition to Mercury and Venus, the other 7 planets have their own moons, which is a system of celestial bodies bound together by the Sun's gravity, including the Sun, planets and their moons, dwarf planets, asteroids, comets, and interplanetary matter, with the Sun located about 260,000 light-years from the Milky Way and 230,000 light-years from the edge.

The main planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Among them, the largest planet is Jupiter, and the smallest planet is Mercury. In addition, there are many asteroids in the solar system.
What planets are there in the solar system
The so-called solar system refers to the collection of all celestial bodies centered on the sun that are constrained by the sun. The solar system consists of eight planets, 173 known moons, five dwarf planets, and hundreds of millions of small bodies in the solar system.
Because the asteroids in the solar system do not have names, and there are relatively many of them. Therefore, at present, only the eight major planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
On August 24, 2006, at the 26th International Astronomical Union, Pluto was kicked out of the ranks of the eight planets. It is combined with Ceres, Charon, Eris, Ornis, and Hauma to form a new classification - dwarf planets.
Among them, Jupiter is the largest planet in the solar system. Its diameter is 142,984 km, and Jupiter's mass is twice that of the other eight planets combined. It can be seen that Jupiter is not only the largest planet in the solar system, but also the heaviest planet.
And the smallest planet in the solar system is Mercury. Mercury has a diameter of only 4878 km and a mass of . Although Mercury is the smallest planet in the solar system, it is also the closest planet to the Sun.
The Earth is the third farthest planet from the Sun, and the Earth is the only celestial body known to have life. In addition to this, the Earth has a natural satellite - the Moon.
Nine planets, including the Earth, form a planetary system that revolves around the Sun. The closest planet to the Sun is Mercury, followed by Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. With the exception of Mercury and Venus, all planets have moons. >>>More

Nuclear fusion is inherently an instantaneous reaction. The nuclear fusion created by humans is only short because of the limitations of human technology. Hundreds of millions of degrees of high temperature are required to meet the conditions for nuclear fusion to occur, and the high temperature that the solid matter that human beings have been able to develop so far can resist is less than 5,000 degrees, which greatly limits the development of artificial nuclear fusion. >>>More
The small bodies of the solar system mainly include moons, asteroids, and comets.
There may be. Human exploration of the Earth is far from enough, and even the solar system has not been explored, so it is not known whether there is extraterrestrial life in the solar system.
