Mankind has always wanted to know about the outer space around us, to learn about the neighboring planets, to explore them, and perhaps to find on one of the planets intelligent life.To date, we have already studied our Solar system with the heavenly body – the Sun, as well as 8 planets, each in its orbit revolve around the Sun. But to know the size of the Solar system, to understand why the planets do not collide, you need to know the distance between the planets. As inhabitants of the earth, I think we are most interested in the distance of the planets from the Sun and the distance between the Earth and the rest of the planets of the Solar system. So, let’s start, perhaps, with our beloved planet Earth, the only planet in the Solar system, where there is intelligent life. This is facilitated by the presence of an atmosphere consisting of oxygen, the presence of water, and a suitable temperature for life, which, incidentally, largely depends on the distance of the Earth from the Sun. The earth moves in the third orbit from the Sun at a distance of 149.6 million km from the celestial body. The closest planet to the Sun – mercury, differs from the rest of the highest recorded temperature on the surface. The sun-turned surface of mercury was heated to 465C. Basically, the planet has achieved such indicators due to the closest orbit to the Sun, because mercury is 57.9 million km from the Sun. To the Earth from mercury also, by space standards, very close – 91.6 million km. Venus, or as it is often called “sister of the Earth”, moves in the second orbit from the Sun at a distance of 108.2 million km from the celestial body. The closest to the Earth, the “red planet” – Mars, moves in the fourth orbit just 78, 3 million km from the Earth. However, unlike Venus and mercury, Mars is located on the outside of the Earth, that is, its orbit is larger than the orbit of the Earth and is remote from the Sun by 227.9 million km. And this already suggests that Mars is a cold planet, because at such a distance the sun’s rays weakly warm the surface of Mars. The next orbits from the Sun, after Mars, already occupy the planets of the Jupiter group, or, giant planets, which are many times greater in mass and volume of the planet of the earth group, but much farther away from the celestial body. The closest giant planet to the sun Is Jupiter, the largest planet in the Solar system. It is distant from the Sun at 778.6 million km From the Earth, Jupiter is 628.4 million km. Behind Jupiter is Saturn – the only planet surrounded by a beautiful disk. It is removed from the celestial body by 1443.7 million km. To the Earth from Saturn 1277.4 million km. Moving in the seventh orbit of Uranus, is the coldest planet in the Solar system. It is also caused by the large distance from the Sun, on 2870,4 million km Distance between earth and Uranus is still 2721,4 million km.The most distant planet from the Sun today is Neptune. This distant planet moves in the eighth orbit in 4491,1 million km from the Sun. From the Earth, this distance is 4347.4 million km.It is worth saying that there is a certain regularity called to cosmology the Bode rule. According to this pattern, each subsequent of the planets of the Solar system is separated from the Sun by an average of 1.7 times. This ratio slightly violates only Jupiter, but otherwise it is understandable, given that all the planets formed around the Sun from a single gas-dust cloud.
