What is the solar system? – The solar system, right in the space where the earth and we live, is a gravitational system consisting of the sun and objects in its orbit that orbit directly and indirectly in orbits around it. The solar system formed a large interstellar molecular cloud 4.6 billion years before the gravitational explosion and collapse. The largest mass of this system (about 99.8%) belongs to the sun.

Introducing the planets of the solar system 
The solar system has eight planets orbiting the sun. The first 4 planets have rocky texture, high mass, and small diameter, while the next 2 planets are gas giants and the last 2 planets are ice giants. Of course, ice does not mean the ice we know in the freezer, but it is actually frozen gas. Scientists have spent many years researching life in different parts of the solar system, and now only one of Saturn’s moons has been able to show signs of microbial life. Guess. Planet Earth is currently the only place in the solar system where life flows. In the following, we will introduce these planets and their characteristics in the solar system.

1. Mercury (Mercury)
You may be wondering at the outset what is the difference between a planet and a star? In answer to this question, it should be said that the difference between the planet and the star should be summarized and categorized based on light, position, size, shape, temperature, number, luminosity, and their constituent material. With this explanation, the planet Mercury is the first And it is the smallest planet in the solar system that has the shortest distance from the sun. The planet can orbit the sun in 88 days. However, the planet is very lazy in its orbit; So that every day and night on Mercury lasts about 58 Earth days! That is, a year is equal to a day and a half! This planet, which was discovered around 14 centuries BC, has a very different average temperature change and reacts according to the direction and interaction with the sun. Its temperature is 427 degrees Celsius in the hottest possible state and 173 degrees Celsius in the coldest state. Another thing about this planet is that it has no moon to orbit.

2. Planet Venus (nicknamed Earth’s sister); The second planet in the solar system
The second planet in the solar system, in terms of distance and proximity to the sun, is Venus. Venus is the closest planet to Earth so that it can be seen with the naked eye in the sky at the beginning of sunset, just when the sun is setting. The dazzling beauty of this blazing flame in the sky is as if another sun rises from the horizon and rises at the same time as the sunsets. The ancient Romans named this planet Venus, the goddess of love and beauty. Venus’ atmosphere is very thick and its orbit around the sun takes 225 Earth days. Venus is slow and moving even slower and even slower than Mercury! So that the days of Venus are longer than its years. Every day and night on Venus lasts 243 Earth days, which means 18 days more than a year! Venus is very hot and its yellowface in the sky indicates a very high temperature and inflammation. So that the surface temperature of Venus reaches 463 degrees Celsius and this means fire!

3. Earth, the third planet in the solar system
Earth, our 4.5 billion-year-old home, is the third planet in our solar system. The Earth has the best vital texture in the solar system; In fact, the Earth’s proper distance from the Sun (something like 150 million kilometers), the right rotation orbit, the right temperature, and the right length of day and night have created a world of life that lasts for billions of years. Earth is the first planet It has a moon in the solar orbit of the solar system and no two previous lunar planets. But what is the moon? The moon is actually a celestial sphere that can be very similar to the planet in terms of texture, atmosphere, and gravity. But the biggest difference between a moon and a planet is its orbit. So that the moon does not revolve around the sun, but is stuck in the orbit of the planet and revolves around the planet. The moon is the only planet on the planet that revolves around the earth about once every 27 days and, of course, revolves around itself at the same time. Therefore, one side of the moon is always hidden from the earth observer and is known as the “orbit of the moon”. This is also the case for other moons in the solar system. This phenomenon is called tidal lock or gravitational lock.

4. Mars (nicknamed Earth Brother); The fourth planet of the solar system

Mars is the fourth planet in the solar system, and mankind has always imagined that this planet could be his second home. For this reason, it has sent many probes to the planet for study and research. However, no sign of life has yet been found in it. Some scientists believe that Mars had life and civilization (not necessarily human) in the distant past, and know that life is over. However, NASA scientists are preparing for human travel to the planet in the third decade of the 21st century.

5. Jupiter or Hormoz; The fifth and largest planet in the solar system
Jupiter is a large gas giant in the solar system that orbits the sun. This planet is the third brightest object in the sky after the moon and Venus, and it has enough light to cast a shadow on the earth. Jupiter is about 1300 times the volume of the earth and is home to huge storms. Its famous storm appears as red spots on the surface of the planet and is known as Hormoz or Jupiter. The planet has the strongest gravitational orbit in the solar system.

6. The beautiful planet Saturn; The sixth planet in the solar system
Saturn or Saturn is a beautiful gas planet and is famous for the rings that surround it. Saturn’s rings are often made of ice, rock, and dust. This giant and beautiful planet have 62 official moons. One of the planets’ moons is so large that it has its own atmosphere. Saturn, like Jupiter, has a high velocity that spins around once every 10 Earth hours. Saturn orbits the Sun for 29 years. The planet was discovered in 800 BC. The Cassini spacecraft orbited Saturn for years, sending scientists a wealth of information about the planet’s moons, seasons, rings, climate, and atmosphere.
