Louis Lagrange mathematician and astronomer. He made significant contributions to the fields of analysis, number theory Structure of Lagrange points There are five Lagrange points around major bodies such as a planet or a star. Three of them lie along the line connecting the two large bodies. In the Earth-sun system, for example, the first point, L1, lies between Earth and the sun at about 1 million miles from Earth. L1 gets an uninterrupted view of the sun, and is currently occupied by the Solar and Heliospheric Observatory (SOHO) and the Deep Space Climate Observatory. L2 also lies a million miles from Earth, but in the opposite direction of the sun. At this point, with the Earth, moon and sun behind it, a spacecraft can get a clear view of deep space. The James Webb Space Telescope will move into this points so after many problem data not possible for the moment Lagrange point, L3, lies behind the sun, opposite Earth’s orbit. For now, science has not found a use for this ...
