Lagrange Points are positions in space where the gravitational forces of two large objects, like the Sun and Earth for example, balance out with the centrifugal force of an orbiting object, creating a point of equilibrium. Lagrange Points are important for spacecraft as it creates a natural "parking spot" that allows them to maintain position while expending very little fuel. There are five Lagrange Points in the Earth-Sol orbit and are often used to "park" satellites, for example NASA's new James Webb space telescope is located at the second Lagrange Point, between Earth and Mars orbital paths, and orbits the sun at a distance of 1.68 million kilometers (1.04 million miles) from Earth.
