Rocky Planets

Why are Rocky Planets in the solar system stuck to the sun?

Posted on

We all know that the planet we humans live in is inside the solar system. There are a total of 8 planets in the solar system, and all of them exist in different forms. If you look at the structure of the solar system, there is a group of rocky planets around the Sun, and gas giant planets a little further away. The less icy planets are even further away.

So there is something to think about. Why do the rocky planets orbit closer to the Sun and the gas giants orbit farther away from the Sun?

What happened when the stars and planets formed and why the solar system is the way it is?

Before we go into those questions, let’s have a brief look at the planets in the solar system.

The rocky planets mentioned above are called Terrestrial Planets. These planets have hard planetary surfaces, They are called rocky planets because they have rocky structures. In the solar system, Mercury, Venus Mars and the planet we live on are rocky planets. Although these planets are not composed of gas, they are not completely devoid of gas layers. If there wasn’t a layer of gas, I wouldn’t even be writing this. We know these gas layers as atmosphere.

Another type is the gas giants. Known as the Gas Giant. As the name suggests, these planets are made up mostly of gas. Some scholars believe that the central poles of the planet are stones, It is estimated that it may be composed of metals. Within the solar system, Jupiter and Saturn are gas giants, many times larger than the rest of the rocky planets.

Another type is the ice planet. A group of planets that are far away from the mother star, the Sun. They are known as Ice Giants. The ice planets are Neptune and Uranus. These planets are larger than the rocky planets, but smaller than the gas planets. It can be said that it is located very far from the sun. Most of the planet’s surface below the upper gas layers of the planet is ice, Covered by icebergs.

How was the solar system born? 

About this topic, ‘How stars are born, I will mention in the comments that I have written an article with the title ‘How are the planets?‘ If you want to know the details, you can read that article.

Roughly speaking, a mass of gas clouds called the solar nebula collapsed due to gravity and gave birth to the Sun. But not all of the material in the nebula went into the birth of the Sun, leaving gas around the edges of the cluster. This mass of gas still revolves around the sun, where the universe was born. As it orbits, some of these elements gather together again due to gravity, and planets are formed through the nebula remnants.

To answer the question of why the rocky planets are so close to the Sun, we have to look at the birth of the Solar System. You will need to go back to the time when the planets were formed.

After the birth of the sun, the planets have gathered together. At the time of formation, the inner elements closer to the sun feel more temperature and are hotter. The outside is a little colder than the inside. The gases in the cooler outer space can exist like this, but the elements inside are in a solid state. Internal melting point – elements with high melting point can exist in solid form. For example, iron, Like silicates. Some experts say that the gas elements inside condense due to the temperature and form a solid state. If you zoom back in, you can see that the elements must exist as solids because the inner part feels the temperature. The meaning is that the inner planets are solid and are rocky planets. From the accumulation of gas on the outside, it became a gas planet. .

There is one more thing that many scientists accept about the structure of the solar system

That is, when the solar system began, conditions were unstable and chaotic. It is said that the sun emits waves of energy such as solar wind and heat waves, and solar storms are occurring on a large scale. At that time, the eastern planets were still covered by a small layer of gas. However, as I just mentioned, the high-energy radiation waves emitted by the Sun are received by the planets that are very close to the Sun, and the gas layers in the planets are separated, leaving only bare pieces of rock. In some hypothalamus, the solar wind and heat waves from the sun at the beginning of the solar system caused the gas planets to move away, and the rocky planets, which are composed of solid rocks, were not too far away.

So if all solar systems have rocky planets very close to their parent star, the answer is no.

When scientists look at the structure of other solar systems, they have found gas planets that are larger than the planets in our solar system and are close to their parent stars.

In summary, why are the rocky planets in the solar system stuck to the sun?

– One is that the internal elements that are exposed to more temperature when they are still forming are assembled in a solid state.

– The second type is because the gas layers of the rocky planets were separated by the sun’s solar wind and other high-energy radiation waves after they were formed, leaving only the rocky surface.
