The planets in the solar system can be broadly divided into two main categories: terrestrial planets and Jupiter-like planets.
Terrestrial planets are formed by colliding and gathering solid particles of matter to become microasteroids, and then aggregating microasteroids.
Jukistans start with the mutual adsorption of water ice, and when the mass is large enough, it further adsorbs hydrogen and methane to form a gas planet.
Terrestrial planet. Members include Mercury, Venus, Earth, and Mars. It is a small, dense rocky world with a rarer atmosphere.
Internal structure: a metal core in the center, surrounded by a stony crust on the outside, with quite a few potholes on the surface, with an average density of about 3-5g cm3.
Giant planets. Members include Jupiter, Saturn, Uranus, and Neptune. It is a world of gases with large volume, large mass, but low density, and a dense atmosphere.
The average density is about g cm3, the density of Saturn is about, and the mass of Jupiter is about 318 times that of Earth. Structure: Inside-out, with a rock core, liquid metallic hydrogen, liquid molecular hydrogen, a gas-filled atmosphere, and swirling clouds on the surface.
In addition, planetary rings and a large number of moons orbit the eight planets of the solar system, with the Sun as the center, in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

It is divided into terrestrial planets and Jupiter-like planets.
Mercury, Venus, Earth, and Mars are terrestrial planets.
Jupiter, Saturn, Uranus, Neptune.

According to the eight planets.
We can divide them into: terrestrial planets, Jupiters, and ice giants. To put it simply, terrestrial planets are basically solid rock planets, Jupiter-like planets are gaseous planets, and ice giants are ice-like solid planets.
The planets of our solar system include: Mercury.
Venus, Earth, Mars, Jupiter.
Eight planets including Saturn, Uranus, and Neptune, and the early Pluto has been relegated to a dwarf planet series. It has not yet been discovered whether there are objects in Neptune's outer orbit that meet the definition of planets.
<> almost all planets orbit the sun in a plane called the ecliptic. These planets are divided into three main groups. The first group is the Earth planets (rocky planets), which are mainly composed of silicate rocks.
They are Mercury, Venus, Earth, and Mars. The second category is Jupiter-like planets (gas giants, mainly composed of hydrogen and helium)."It is mainly composed of hydrogen and helium"Instead"It is mainly composed of hydrogen and helium"), Jupiter and Saturn, respectively. The third group of ice giants is Uranus and Neptune, which are mainly composed of water, ammonia, and methane.
composed of ice-like solids.
Land planets are mainly solid planets made of rock and silicate. They are Mercury, Venus, Earth, and Mars. They are known as terrestrial planets because other planets are rocky and solid like Earth.
Mercury, the smallest planet in our solar system, is the closest planet to the Sun and has a lifeless, mostly rocky surface that resembles the Moon.
Venus, which has a dense, Earth-sized atmosphere on its surface.
The environment is very harsh, with a rock-like solid atmosphere underneath. Then there is the Earth, where we live, the atmosphere plus rocks. Next is Mars, which has a thinner atmosphere with a red surface and rocky solids.
Europa. Planets are mostly gaseous planets and are sometimes referred to as gaseous giants. They are Jupiter and Saturn, and they are called Jupiter because Saturn is similar to Jupiter.
Jupiter is the largest planet in the solar system. Jupiter does not have a solid surface, it has a gaseous surface. The most prominent feature of Jupiter's surface is its beautiful Great Red Spot, which has been around for hundreds of years.
Saturn is the most fascinating object in our solar system, and it is fascinating because of its beautiful rings. But you can't see it with the naked eye, only with a telescope. Saturn also does not have a solid surface and has a thick atmosphere.

If it is classified according to the structural characteristics of the eight planets, it can be divided into three categories, which are terrestrial planets, mainly including Mercury, Venus, Mars, and Earth. The second category is the perihelia planets, which are Uranus and Neptune. The third category is the giant planets, which are Jupiter and Saturn.
-
They are divided into: terrestrial planets, Jupiters, and ice giants. Earth-like planets are solid rock planets, Jupiter-like planets are gaseous planets, and ice giants are ice-like solid planets. And there's a scientific basis for that.
-
Terrestrial planets, ice giants, Jupiteres, inland planets are made up of some solid rocks, ice giants are formed from some solid ice, and Jupiters are formed by some gases.

The Sun is a star, there are eight planets in the solar system, and our Earth is also one of the eight planets. It is divided into different tracks and runs separately.
-
The planets of the solar system can be divided into 3 categories. Earth-like planets: Mercury, Venus, Earth, and Mars.
These planets are all made of rocks and are closer to the Sun. Jupiter-like: Jupiter, Saturn, Uranus, and Neptune.
These planets are massive, hundreds of times the mass of the Earth. They both have dense atmospheres with hydrogen as the main component, followed by helium, ammonia, and methane. These gases may cover a core made of rocks.
Other objects: comets, asteroids, and objects in the Kuiper Belt. These celestial bodies are made up of a mixture of rocks and ice.

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 major planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The largest of these planets is Jupiter, and the smallest planet is Mercury. In addition, there are many asteroids in the solar system.
The so-called solar system refers to the collection of all celestial bodies with the sun as the center and subject to the sun's gravitational pull. The solar system includes eight planets, 173 known moons, five dwarf planets, and hundreds of millions of small solar system bodies.

Mercury: Closest to the Sun. The revolution period is very short, 88 Earth days.
The rotation is very slow, it takes 59 Earth days to rotate for one week. Surface temperatures vary widely. Venus:
The climate is very harsh, covered with clouds of carbon dioxide and sulfuric acid, with a surface temperature of nearly 500 degrees Celsius and extremely high atmospheric pressure. Earth: The surface of the land and sea is unevenly distributed, known as the water hemisphere.
The land area occupies , which is still smaller than the water area. There is oxygen, which is suitable for the survival of living organisms. Mars:
The surface drop is large. The surface is covered with structures that resemble river channels, and was once thought to be the remains of Martians. Jupiter:
The largest planet has a mass that is twice the sum of the speed of the other 8 planetary masses. to find the second most satellites. The first of the 4 gaseous planets.
Saturn: to discover the most moons. It has a ring structure that is less than a kilometer thick, but extends 420,000 kilometers from the planet's surface into space.
Uranus: Most planets rotate around an axis that is almost perpendicular to the ecliptic, but Uranus's axis is almost parallel to the ecliptic. Neptune:
Gas planets. The structure is similar to Uranus, and because of methane, it is a blue planet. Pluto:
The farthest and smallest planet from the Sun, there are seven moons in the solar system larger than Pluto.
The planet is out of the gravitational range of the star in its motion around the star. Taking the solar system as an example, planetary escape means that all eight planets have left the solar system, and the fundamental reason is that the gravitational pull of the stars becomes smaller, and the planets cannot be restrained from continuing to move in their original orbits.
After studying the asteroid Cleopatra, astronomers determined that the asteroid was a unique object in the solar system. >>>More

Yes, because the earth has an atmosphere, the temperature can generally be considered to be around 20, while the moon has no atmosphere, and the temperature can reach more than 100 degrees on the side facing the sun, and about -270 on the side facing the sun. So the temperature difference between the Earth and the Moon is huge. Other planets are either very far from the Sun, and the planets and their moons are very cool, like Jupiter and Saturn. >>>More
