"In the universe, this combination of the solar system is one in a million."
The words of Qian Haiyuan, a professor at the School of Astronomy at Nanjing University, attracted the attention of many people.
He revealed that the solar system is not unique, but the combination of solar systems is really rare in the universe, and some astronomers even believe that the solar system was designed.
Professor Qian Haiyuan is a professor at the School of Astronomy at Nanjing University, with a research interest in planetary physics.
He said that this orderly combination of planetary masses in the solar system is so rare in the universe that no planets that are highly similar to it have been found in the current observational data, so we cannot rule out the possibility that the solar system was designed.
And the earth in the solar system is so rare, what are the planetary systems that can provide a stable environment for the earth?
Professor Qian Haiyuan also said that people are quite emotional, he said that it is precisely because the earth can provide us with such a stable environment that life can continue to evolve.
So it can be said that without the solar system, there would be nothing on this planet where we came here.
So for the earth, what is the importance of the existence of the solar system to the role of life on the earth?
First, the solar system can provide a stable environment.
The solar system was born out of an atmospheric cloud about 4.6 billion years ago.
At the same time, observations from Kepler satellites have also discovered hundreds of galaxies with prototype forests.
In an atmospheric cloud in the solar system, there is a supernova explosion near the star, and the shock wave and ultraviolet rays emitted by the supernova explosion have an extremely important impact on the atmospheric cloud, and at the same time, it will also accelerate the movement of dense cloud gas towards the center of the cloud.
This is known as a "gamma-ray burst".
As a large number of atmospheric clouds gather, the gravitational pull will become more and more intense, and this gravitational pull, along with the light pressure of the star, will enter equilibrium.
When the density reaches a certain point, the gravity of the cluster remains constant, and the clouds of the star in the densest region of the cluster begin to collapse gravitationally, and the star cluster is formed, and the star in it will begin to fuse hydrogen nuclei in about 500,000 years, thus forming a star, and the Sun is such an ordinary main-sequence star.
After the formation of the Sun, the remaining gases continue to move around the Sun, and at the same time, it also undergoes a series of collisions to gradually form planetary systems and planets.
The mass of the Sun is also the largest in the solar system, accounting for about 99.86% of the total mass of the solar system, and the remaining 0.14% of the mass is occupied by planets, dwarf planets, Saturn's rings, and celestial bodies such as comets and meteors.
Zhu Qiping, a famous astronomer, popular science writer, and author of "The First Lesson in Space", once introduced the formation process of the solar system in his book.
The solar system is constantly colliding and moving, and the sun's radiation and solar winds will have a huge impact on the stars produced.
At the same time, it can also help us understand that the forces generated by collisions within the solar system are also enormous.
Similarly, the effect of Earth's gravity on other celestial bodies in the inner solar system is very obvious.
Sometimes, the gravitational pull of the Earth also causes the movement of the Moon, which in turn affects the tidal motion of the Earth's sea.
But what about Earth's influence on the other planets in the solar system?
2. The influence of the Earth on other planets in the solar system.
The Earth is known to be the closest to the Sun.
Also for this reason, the gravitational influence of the sun is most pronounced on the Earth.
In the solar system, the gravitational pull of the Sun is in descending order: Jupiter, Saturn, Neptune, Mars, Venus, Earth, and Mercury.
At the same time, the Earth has a significant gravitational pull on about 47 small objects, as well as objects such as the asteroid belt and the Alkugan family.
Everything on Earth is also affected by the gravitational pull of these celestial bodies, resulting in so-called "solar terms", lunar eclipses, solar eclipses, and comets.
On the other hand, the effects of other planets in the solar system on other planets within it are also varied.
It is precisely because the trajectory and motion of the planets in the solar system are affected by other planets that they have a strong collision nature.
Hence the so-called "explosion of collisions between stars and planets", and gamma-ray bursts are one of them.
This also implies that the Earth needs to be protected by other planets in the solar system in order to provide a stable environment for life at all times.
3. There are other combinations of the solar system.
The formation of the solar system is not always unique.
Although we are pleased with the current composition of the solar system, due to the uncertainty of the formation and evolution of the solar system, it is precisely we who cannot rule out that the solar system may exhibit unique characteristics compared to other galaxies.
It is possible that in more planetary systems, a combination of planetary systems with a high degree of similarity to the solar system will be discovered, but it is also possible that there will never be a more life-friendly planetary system than the solar system.
It's not that the solar system is one in a million, and there will be other planetary systems that don't have such a combination.
There are countless star catalog systems in the universe, and most of these star systems contain more planets than the eight planets contained in the solar system.
Therefore, this means that even if there are no other similarities in the solar system, they are only a handful of the universe.
Precisely because the formation of the solar system is full of serendipity.
Therefore, it can be said that even if there is a future formation of a planetary system, it is possible that a combination similar to the solar system will be selected in the process of its formation.
But this is only a possibility, and we should not believe in the possibility in everything, but we should sit on the truth in the universe.
However, it is the emergence of the solar system that allows us to express ourselves and also gives us the opportunity to find other planetary systems outside the solar system.
The solar system is divided into a stable system environment, but it also faces threats from the external environment, such as asteroids, comets, Mars, fireballs, etc., which are all threats from the solar system and need to be paid more attention.
epilogue
The solar system that allows the Earth to provide us with a stable environment is so important.
It is the emergence of the solar system that has given us more opportunities to find extraterrestrial life.
At the same time, the study of the solar system will also be of great help to us to better explore other planetary systems.
And the uniqueness of the solar system also makes it more valuable for research.
