Earth comes in order of size in rank, and the planet is known as the celestial body that revolves around the sun, and it has enough mass to withstand the hydrostatic balance that characterizes it with its circular shape, and the solar system includes eight major planets. Through it, the reason for naming the solar system and its basic divisions will be determined, in addition to arranging the planets of this system in terms of size and distance from the sun.
Earth by volume categorized
The solar system is defined as the system made up of the sun and the bodies that orbit around it. This system includes the Earth and all other planets, as well as smaller bodies such as meteorites, asteroids, comets, dwarf asteroids, and natural elements. . The satellites, otherwise known as planetary satellites, include more than 150 moons. This system is the so-called planetary medium, which is a cloud of gas and dust, and the correct answer to the question of the Earth in terms of size is classified as follows
- Fifth place.
The planets in the solar system are diverse, varying in size, temperature, and environment for each one. Earth ranks fifth in size in the solar system, with Jupiter, Saturn, Uranus and Neptune being the largest. By volume, respectively.
Arrange the planets of the solar system by size
Jupiter is the giant planet, because it is the largest in the solar system, and therefore is the planet responsible for attracting smaller objects in its path, while Mercury is the smallest, and according to statistics conducted by NASA, the following table shows the order of the planets in terms of size and radius of each of them as well to its size relative to the earth
|Planet name||Radius (km)||Size relative to the Earth|
The order of the planets in order of distance from the sun
Mercury is the closest planet to the sun, at a distance of about 58 million km, while Neptune is the farthest in terms of distance.
|Planet name||distance from the sun (km)||Distance from the Sun (miles)|
|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 km|
|Neptune||4.5 billion km||2.8 billion km|
Why is the solar system called?
The solar system is called this because the sun is the main element in it, because 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. It is very difficult to imagine the size of the sun, which is 93 million miles, and Jupiter constitutes 0.14% of the mass of this system, which is the largest planet in terms of size, and the general arrangement of this system is represented by the emergence of the sun in the center and constantly revolving around it four small inner planets, and these planets are surrounded by a belt Asteroids, followed by the four gas giants, are surrounded by a belt of icy bodies called the Kuiper Belt.
Solar System Structure
Astronomers have divided the solar system into two main parts according to the structure of its constituent bodies, the outer solar system, which consists of objects beyond the asteroid belt and includes the four giant gas planets, and the inner solar system, which includes the asteroid. The four rocky belts and planets, and here is a summary of each
outer solar system
The planets in this section are larger than the inner planets, and their orbit is behind the orbit of Neptune, which is why it is called the region behind Neptune, and it is made of heavy liquid metals.
inner solar system
The planets of the inner group are characterized as rocky planets, because they consist mainly of minerals and silicates, in addition to their proximity to each other and the sun, and they are few moons unlike the outer group because they contain only three moons. Two of them are for Mars and one for Earth, and this system includes the planet Mercury. Venus, Earth and Mars, in addition to the asteroid belt, which is the area between Jupiter and Mars.
With this explanation, we end this article in which the correct answer to the question of the Earth is classified in terms of size, in addition to treating the order of the planets in the solar system in terms of size and distance from the sun. The reason for naming the solar system and its basic divisions.
