WebDec 27, 2024 · Webb’s orbit is around L2—a point of gravitational balance on the other side of Earth from the Sun—but it does not reside exactly at the L2 point. Right at that point, Earth’s shadowing of the Sun would be large enough to greatly reduce the amount of power available for Webb’s solar arrays, without greatly simplifying the cooling challenges.

WebWebb's orbit around L2 is known as a halo orbit which, rather than a single path, is an orbit that periodically varies through a series of paths around L2.
