What are Lagrange's points?

Lagrange points are stable gravitational points in a space where an object could be placed, and remains in a firm position with respect to the body orbiting the sun like Earth. Each orbiting planet has five lagrange points. Lagrange points of the country are called l _{1 , l 2 , l 3 , l 4 and l 5 . Lagrange points often appear in discussions about space or sci -fi, because it would be the ideal places to create space stations. This is about five times to far from the ground like the Moon, and would require a trip for about two weeks in a modern spacecraft. When Earth turns around the Sun, these two points rotate with it around the sun and always remain in the same place due to the planet. These stable orbits are through the eyes of the deployment of satellites that observe the ground-month system.}

two more Lagrange points - l _{4 and 5 - JSOU located on both sides of the Earth relative to the sun, lies 60 ° in front of the ground and 60 ° behind the ground in its orbit around the sun and contain interplanetary dust. The Earth-Moon system also has these lagrange points that may contain interplanetary dust grouped into what is called Kordylewski Clouds. L 4 and 5 The Sun system is also called triangular points Lagrange or Trojan points. The latter name comes from the Trojan asteroids in the Sun - Jupiter L 4 and L 5 points. Each planet has its own Trojan points and the larger the planet, the more interstellar dust will be found.}

The last point of Lagrange is L _{3 . This lagrange point is located the farthest from the ground, on the other side of the sun. Until the development of interplanetary probes, which could travel to the areas of the solar system outside the ground and the moon, could never be observed due to its location. This led some mystics to the postulation of the existence of "anTi-Země ", although it turned out to be false. Billions of years ago it is assumed that the size of Mars called Theia was formed in l 3 . Her orbit has become unstable until it eventually collided with the ground.}
