The solar system is the parent galaxy of the earth. The sun is the most central star around which eight planets orbit. As we all know, the star can emit dazzling radiant energy due to its internal nuclear fusion reaction, which brings some warmth and light to the cold and dark universe.
With the existence of the sun, the solar system not only attracts eight planets and other asteroids, but also brings some warmth and light to the solar system. It is because the earth is in the livable zone and just the right distance from the sun that it has the right warmth and light, the birth of life billions of years ago, and the birth of human beings millions of years ago.
If there is no sun, there will be no earth, the planet of life, and there will be no human birth. It can be said that the sun is the mother of life on earth. In ancient times, many tribes worshipped the sun as a totem. After entering the era of science and technology and having the ability to walk out of the earth, human beings began to continuously explore and study the sun.
Through the study of the sun, scientists found that the nuclear fusion inside the sun is hydrogen nuclear fusion, which uses hydrogen as fuel to realize the nuclear fusion reaction. When two hydrogen atoms converge into a helium atom, part of the mass will be lost. According to careful calculation, scientists found that the sun will lose about 4 million tons of mass per second.
In our opinion, it’s a huge number, but for the mass of the sun, it’s just a drop in the bucket. Some friends see that the sun loses so much mass every second. The mass lost in the long run is astronomical. If so, what effect will the sun’s constant loss of mass have on the planets?
We all know that in the vast universe, mass is the most important thing. The larger the mass is, the stronger its gravity is, and the more it can attract more people to move around it. So is the sun, and so is the supermassive black hole at the center of the galaxy. The reason why the eight planets revolve around the sun is that the mass of the sun is much larger than them, and the strong gravity firmly attracts the planets.
If the mass of the sun is lost by 4 million tons per second, its gravity will be weakened. As time goes by, will the sun not have enough gravity to bind the eight planets? Is it possible for the eight planets to leave the sun? In fact, this kind of worry is totally unnecessary. Yes, the sun loses 4 million tons of mass per second, which is a huge amount in a year. The longer the time is, the larger the number is. It’s really an astronomical number.
Scientists have calculated that in the past 4.6 billion years, the sun has lost the mass of 46 Earths by nuclear fusion. Does the loss of so much mass have no effect on the solar system and other planets? Scientists say there is no doubt that the constant loss of the sun’s mass will weaken its gravity.
But the mass of the sun accounts for 99.86% of the total mass of the solar system. Even if the mass of the sun is lost, its gravity is enough to maintain the stability of the solar system, and the eight planets can not escape from the gravitational shackles of the sun. Of course, the continuous loss of the sun’s mass also has some minor effects on the planets around it and the entire solar system.
For example, stars that revolve around the sun will gradually move away from the sun with the continuous loss of the sun’s mass. To test this conjecture, scientists launched a probe to measure the movement of mercury, the closest to the sun. The results show that in the course of about four years of exploration, scientists found that the orbit of Mercury will increase with the decreasing mass of the sun every year, which indicates that Mercury is also a little bit away from the sun.
Mercury is like this, so are other planets, but the speed and amplitude of the distance are very small, maybe only a few centimeters per year. When scientists observe the moon, they also find that the moon has been quietly away from the earth since it became an earth satellite. In ancient times, the moon was very close to the earth. People can see the larger moon when they stand on the earth. Naturally, they can also see some conditions on the surface of the moon. Therefore, there are many records about the surface of the moon in some ancient records.
The continuous distance of the moon from the earth may be a combination of many factors. Among these factors, the continuous decrease of the sun’s mass leading to the continuous weakening of the moon’s gravity may be a very important reason. The continuous decrease of the mass of the sun will make the scope of its gravitational circle shrink. Maybe we can’t see any influence now, but after hundreds of millions or billions of years, some asteroids on the edge of the solar system may break away from the shackles of the solar gravity, escape from the solar system, enter interstellar space and become wandering asteroids.
In fact, with the continuous loss of the sun’s mass, it also means that the life of the sun is decreasing. After 5 billion years, the sun will usher in its final glory. After rapid expansion, it will begin to collapse inward, and supernova explosion will occur. At that time, the orbits of mercury, Venus and the earth will all be engulfed. After the supernova explosion, the sun’s core will compress and evolve into a white dwarf.
At that time, the solar system could not be called the solar system. Because the star sun evolved into a small white dwarf, the order and orbit of the original solar system would be reorganized and become a new galaxy. The center of the galaxy was a white dwarf, surrounded by a variety of celestial bodies. Maybe someone will ask, where were human beings at that time?
If human civilization can continue to develop, billions of years will be enough to turn human into a powerful interstellar civilization in the universe. At that time, human beings may have gone out of the solar system and colonized more galaxies. Therefore, billions of years later, human beings may not be in the solar system, but throughout the entire galaxy and even other corners of the universe. At that time, human beings had countless colonial and resident planets, and the end of the sun would not affect human beings at all.
