🌌 How can the James Webb Space Telescope orbit something that isn’t even there? Welcome to Lagrange Point L2—a spot in space where the gravity of the Sun and Earth centrifugal force balance out just enough for JWST to orbit the Sun with Earth. Since L2 isn’t a physical object but an unstable point, JWST uses a halo orbit—like “surfing” a saddle in space. Constant motion keeps it stable, with small course corrections. Why L2? ✅ No eclipses ✅ Constant cooling ✅ Unobstructed view ✅ Stable communic
