Lagrange Points: The Gravitational Sweet Spots We Park Spacecraft In

In any two-body gravitational system — like the Earth and the Sun — there are five special positions where a third, smaller body can sit in a stable or semi-stable equilibrium. These Lagrange points are some of the most valuable real estate in the solar system: the James Webb Space Telescope sits at L2, SOHO monitors the Sun from L1, and future space settlements have been proposed at Earth-Moon L4 and L5.
