Space Fact #2: Parts of Space Are Flat Plains

Lagrangian points are the “flat” places in space where the pulling and pushing forces are in balance. The orbiting object constantly pushes away from one body, held back by gravity, while the pulling of a second body keeps the object in the same place relative to the two large bodies. (Paul A. Tipler, Elementary Modern Physics, Chapter 9: Astrophysics and Cosmology)
