The Lagrange System refers to a set of five points in space, known as Lagrange Points, where the gravitational forces of two large bodies, like the Earth and the Moon, create a stable environment for smaller objects. These points allow spacecraft to maintain a stable position relative to the two larger bodies with minimal fuel consumption. The five Lagrange Points are designated as L1, L2, L3, L4, and L5. Each point has unique characteristics; for example, L1 is located between the two large bodies, while L4 and L5 form an equilateral triangle with them. These points are useful for space missions and satellite positioning.
