How many planets are there in the solar system?

Today, dear reader, we will talk about importantknowledge. Let us say, however, that they are unlikely to be useful to us in everyday life or in everyday life. It's about the solar system, where our planet is. 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 spaceThe universe is organized according to one principle. In each of them there is a central star. Our star is called the sun. Around the central star rotates a certain number of objects, which, as a rule, act as planets. The solar system can include a very different number of celestial objects. Our planet for the Sun is like the Moon for the Earth. However, the nature of the interaction of the central star with its objects is quite different.

Our solar system includes a set of eight planets. Here, how many planets in the solar system. Let's talk a little about each of them.

The first planet, which is closest toThe sun is the planet Mercury. In addition to its proximity to our luminary, Mercury is also known for being the smallest planet in the terrestrial group of our solar system. This small planet has a very thin bark 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 life impossible in the atmosphere of Venus impossible. The small amount of water and the saturation of the Venusian atmosphere with greenhouse gases make the planet completely unfit for development.
Planet Earth is our home. The earth is the densest planet in the inner group of the solar system. The peculiarity of the planet, of course, can be called the hydrosphere, which gave life to all living things. Radical difference in atmospheric conditions of the planet Earth allocates 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 in the solar system are internal plan. The red color of the celestial body is caused by the presence of a large amount of iron oxide in the earth's soil. Mars is known for its largest volcano Olympus, which reaches a height of more than 20 kilometers. This giant is higher than all the volcanoes on planet Earth. Mars has two satellites Phobos and Deimos, which, according to the latest data, are captured by asteroids.
Jupiter is a giant planet that isrepresentative of the outer circle of our solar system. The planet has mainly hydrogen and helium. Jupiter is accompanied by 65 satellites. Some of them are very similar to the Earth in many ways. Ganymede is the largest satellite of the solar system. He is greater 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 these is Titan, which has a significant atmosphere and is of particular interest to the future of mankind.
Uranus is the lightest planet of an external groupour solar system. The undeniable feature of this celestial object is the rotation angle 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 emits the minimum amount of heat into space.
Well, the last planet, which is in the verythe cold corner of our solar system, is called Neptune. The planet is known for its Triton satellite, 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.
