WebL2 is further away than the Moon, almost 4 times further, I believe. The shadow of the Earth is teensy at that point, that's not why it's there. It's there because it's stable and it's able to point away from Earth, Moon, and Sun all at the same time and thus avoid our combined infrared interference. WebFeb 11, 2024 · The James Webb Space Telescope (JWST) arrived at its new home, Lagrange point L2, on 24 January 2024, after its launch on Christmas Day, 2024. Here, it will stay, orbiting around this gravitationally special position 1.5 million km away for the next 10 or 20 (or more) years, as L2 itself orbits the Sun, keeping Earth behind it.

The extra pull of Earth's gravity decreases the object's orbital period, and at the L 2 point, that orbital period becomes equal to Earth's.
