Which orbital point lets telescopes like JWST hover with Earth?
- Lagrange point L2
- Lagrange point L1
- Geostationary orbit
The answer is Lagrange point L2. L2, 1.5 million km out.
In celestial mechanics, the Lagrange points, also called the Lagrangian points or libration points, are points of equilibrium for small-mass objects under the gravitational influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem.
