From the accumulation of results of astronomical and space studies and observations and analysis of all celestial bodies in the solar system relative to the mother planet Earth, we have been able to extract important facts. Because of the environmental conditions, temperature, gravity, gas composition, and water suitable for humans, animals, and plants, we found that Earth is currently the only life in the solar system. It is the basis for the existence of life, be it intelligent, animal or plant. A creature, will they not believe?” And, besides that, it represents the medium in which the first cell was born and grown; Because that medium is available on earth in different conditions like depth, cold, light, salinity. It is a laboratory where different types of organisms have appeared and developed before going to land. Because the present shielding gas protects against dangerous cosmic heat and radiation before the atmosphere is formed.

As for other planets in the solar system, they are either extremely hot, like Mercury and Venus, or extremely cold or gravitational. For example, the average temperature of Jupiter (-140°C), Saturn (-185°C), and Uranus (-224°C), Neptune (-220°C), Pluto (-230°C), and Mars Also, it has long been a candidate for life. Still has a temperature of (-70 degrees Celsius), in addition to the results of several spacecraft, the idea of ​​​​life has spread to its surface.

Heavier planets like Jupiter and Saturn hold light gases like hydrogen and some light gases like ammonia and methane. As for the light planets like Mercury and Pluto, they have no gaseous atmosphere and are exposed to a large number of meteor strikes and deadly radiations like cosmic rays and ultraviolet rays, as well as Venus and Mars. High percentage of heavy gases, due to lack of water. There are different celestial bodies beyond Neptune and Pluto because they are much colder than Pluto’s temperature and most of them are ice so life cannot grow and develop on them.

In all these considerations, life has become very rare on the planets and bodies of the solar system, and the chances of its existence on other bodies are probably a small percentage, perhaps even less with large numbers of stars (1%). Although it is found on a planet, it is difficult to communicate with due to its deep distance and currently inefficient communication technology.

With this sense, we can say: There is little hope of finding life on other planets and in our solar system (at present), but it would be a mistake to limit ourselves to the search for life on the solar planets. system alone; Because they are the coldest bodies in our universe, whose stars (suns) exceed 1,000 trillion stars, apart from planets orbiting each other and stars in the final stages of development, such as dwarf stars. , neutrons and black holes.

We found that the Solar System is located in the Milky Way, which consists of about 150 billion stars, about 100,000 light-years in diameter. The Sun is about 30,000 light-years from the center of the galaxy, and its speed within the galaxy reaches 250 km/s, thus completing one revolution in approximately 250 million years. This cycle is called the Hungarian year.

The location of the solar system in the galaxy contributes to the balance of the planets, including the earth, and preserves life on our planet, “and He raised the heavens and set them in balance”, al-Rahman 7, so the orbit of the solar system around the center of the galaxy is almost circular, and it rotates at the same speed as the rotation of the spiral arm of Orion. , meaning they rarely cross it.

And since there are no major dangers such as supernova stars at hand, this gives Earth a greater chance of long-term interstellar survival and stability, in addition to the fact that the Sun is far from the star’s crowded region. At the center of the galaxy. And if the Sun were located near that region, the gravity of the stars would have affected the bodies of the Oort cloud, sending many meteors into the inner solar system, causing meteor collisions with Earth with catastrophic consequences. Cosmic rays from the galactic center can also affect life on Earth. Even at the Sun’s current location, scientists believe a supernova explosion affected life on planet Earth 35,000 years ago by ejecting radioactive dust grains and large meteorites toward the Sun (and God Almighty knows better).
