How many planets in the solar system?
Today, dear reader, we will talk about important knowledge. We will say, however, that they can hardly be useful to us in everyday life or in everyday life. It's about the solar system, where our planet is located. We will answer the main question of the article about how many planets in the solar system. So:
The solar system and its planets
Any solar system in the whole space of the Universe is organized according to one principle. Each of them has a central star. Our star is called the sun. Around the central star rotates a number of objects, which, as a rule, appear in the form of planets. The solar system may include a very different number of celestial objects. Our planet for the Sun is the same as the Moon for the Earth. However, the nature of the interaction of the central star with its objects is completely different.
Our solar system includes a set of eight planets. That's how many planets in the solar system. Let's talk a little about each of them.
- The first planet that is closest to the Sun is the planet Mercury. In addition to its proximity to our luminary, Mercury is also known for the fact that this is the smallest planet in the earth group of our solar system. This small planet has a very thin crust and a large iron core.
- The second planet from the Sun is Venus. The planet is slightly smaller than our Earth. The surface temperature is 400 degrees Celsius, which makes it impossible to develop life in the atmosphere of Venus. The small amount of water and the greenhouse gas saturation of the atmosphere of Venus makes the planet completely unsuitable for exploration.
- Planet Earth is our birthplace. Earth is the densest planet in the inner group of the solar system. A feature of the planet, of course, can be called the hydrosphere, which gave life to all living things. The radical difference in the atmospheric conditions of the planet Earth distinguishes it in the entire solar system. The earth has the most favorable conditions for the existence and development of life.
- Mars is the fourth planet from the Sun. It completes a series of inner planets and helps answer the question of how many planets are in the solar system of the inner plan. The red color of a celestial body is caused by the presence of a large amount of iron oxide in the earth of the planet.Mars is known for its largest volcano, Olympus, which reaches a height of more than 20 kilometers. This giant is above all volcanoes on planet Earth. Mars has two satellites Phobos and Deimos, which, according to the latest data, are captured asteroids.
- Jupiter is a giant planet that represents the outer circle of our solar system. The planet is composed mainly of hydrogen and helium. Jupiter is accompanied by 65 satellites. Some of them are very similar to Earth in many ways. Ganymede is the largest satellite of the solar system. He is more than Mercury.
- The next gas giant is Saturn. This planet can be recognized by a unique system of asteroid rings orbiting the planet. An interesting fact is that Saturn is the least dense planet in the solar system. Its density is close to the density of water on Earth. According to the latest data, Saturn has 62 satellites. The most remarkable of them is Titan, which has a substantial atmosphere and is of particular interest to the future of mankind.
- Uranus is the lightest planet of the outer group of our solar system.An indisputable feature of this celestial object is the angle of rotation of its axis. If we can compare all the other planets with a top, then Uranus is rather a ball that rolls in orbit around the sun. Possessing a sufficiently cold core, Uranus radiates a minimal amount of heat into space.
- Well, the last planet, which is located in the coldest corner of our solar system, is called Neptune. The planet is known for its satellite Triton, which rotates in the opposite direction from the direction of rotation of Neptune itself.
Total: 8 planets - that's how many planets in the solar system.
