The Lagrange Points are five positions in space where the gravitational pulls of a large object, like the Earth or the Sun, and a smaller object, such as a satellite, balance each other out. This creates regions of stability where objects can "park" with minimal fuel usage for maintaining position. These points are crucial in space exploration and are often used for placing satellites, space telescopes, and even future space colonies. The first three Lagrange Points, L1, L2, and L3, were discove
