Lagrange point

A Lagrange point is a position in space where the gravitational forces of two large bodies, like a planet and a star, balance with the motion of a smaller object, creating a relatively stable location. These points are essential for space exploration, as they allow spacecraft to hover with minimal fuel, and in modern applications, they're used for telescopes and satellites to maintain uninterrupted observations. Think of them as cosmic sweet spots that make long-term missions feasible without constant adjustments.
