The earth has dimensions, the planet is known as the celestial body that revolves around the sun, and it has sufficient mass to bear the hydrostatic balance that characterizes its circular shape, and the solar system includes eight main planets, and because of the name of the solar system and its main divisions, in addition to the arrangement of the planets of this system in terms of size and in terms of their distance about the sun.
The land is arranged by size
The solar system is defined as the system Consisting of the sun and the bodies that revolve around it, as this system includes the Earth and all other planets, in addition to smaller bodies such as meteorites, asteroids, comets, dwarf asteroids, and natural satellites. . This system is what is called the medium between the planets, which is a cloud of gases and dust, and the correct answer to the question about the size of the Earth is in order
- Fifth place.
Where the planets differ in the solar system, as they differ in their size, temperature, and the environment of each of them, and the Earth is the fifth largest planet in the solar system, such as Jupiter, Saturn, Uranus, and Neptune. The largest in size, respectively.
The location of the planets in the solar system by size
Jupiter is a giant planet, it is the largest in the solar system, and therefore it is responsible for attracting smaller objects in its path, while Mercury is the smallest, according to statistics conducted by NASA. The space agency, in the following table shows the arrangement of the planets according to size, the radius of each of them in addition to its size relative to the Earth
| Planet name | radius (km) | Size relative to the Earth |
| Jupiter | 69 911 | 1120٪ |
| Saturn | 58232 | 945٪ |
| Planet Uranus | 25362 | 400٪ |
| Neptune | 24622 | 388٪ |
| Planet Earth | 6371 | |
| Venus | 6052 | 95٪ |
| Mars | 3390 | 53٪ |
| Planet Mercury | 2440 | 38٪ |
The location of the planets in distance from the sun.
Mercury is the closest planet to the sun, as it is about 58 million km away from the sun, while Neptune is the farthest in terms of distance. The following table shows the locations of the planets in the solar system in terms of their distance from the sun. except for the distance between them
| Planet name | Distance from the sun (km) | Distance from the sun (miles) |
| Planet Mercury | 58 million km | 36 million miles |
| Venus | 108 million km | 67 million miles |
| Planet Earth | 150 million km | 93 million miles |
| Mars | 228 million km | 142 million miles |
| Jupiter | 778 million km | 484 million miles |
| Saturn | 1.4 billion km | 886 million miles |
| Planet Uranus | 2.9 billion km | 1.8 billion miles |
| Neptune | 4.5 billion km | 2.8 billion miles |
What is the reason for the name of the solar system
The solar system is called this because the sun represents the main element in it, as its mass is more than 99% of the mass of the solar system, and therefore it has almost the mass of the entire solar system, and it is also very difficult to imagine the size of the sun, which is located at a distance of 93 million miles, Jupiter constitutes 0.14% of the mass of this system, and it is the largest planet in size, and the general arrangement of this system is the sun, which is in the center, and four small inner planets revolve around it constantly, and these planets are surrounded by the asteroid belt, followed by the four giant gas planets, which are surrounded by A belt of icy bodies called the Kuiper Belt.
structure of the solar system
Astronomers have divided the solar system into two main parts according to the structure of its constituent bodies, which is the outer solar system, which consists of objects located behind the asteroid belt and includes four gas giants, and the inner solar system, which includes the asteroid belt and four rocky planets, and the following is an overview of each Of which
outer solar system
The planets of this section differ in that they are larger than the inner planets, and their orbit is located outside the orbit of the planet Neptune, and therefore it is called the region behind Neptune, and it consists of heavy liquid metals.
the inner solar system
The planets of the inner group are rocky planets, because they consist mainly of minerals and silicates, regardless of their proximity to each other and the sun, and they have few moons, unlike the outer group, because they contain only three moons, two of which are Mars and one for Earth, and it includes This system includes the planets Mercury, Venus, Earth, and Mars, as well as the asteroid belt, which is the region between Jupiter and Mars.
To this extent, we conclude this article, and thanks to it, the correct answer to the Earth question was determined in terms of the size included in the order, in addition to determining the location of the solar system planets in terms of size and distance from the sun, and the reason for naming the solar system and its main divisions.
