exchemist Posted December 30, 2021 Share Posted December 30, 2021 I see that it is said the telescope will not just sit at L2 but will be in orbit around it. I don't understand how this works, as I gather that L2 is at a "peak", rather than a"hollow", in the gravitational field due to the Sun/Earth system, with the result that objects at L2 will drift away from it (rolling down the slope, as it were), unless artificially returned to it at intervals. If this is right, how can the telescope orbit L2? Can someone explain? Link to comment Share on other sites More sharing options...
