WebDec 30, 2009 · At L1 (as well as at the other Lagrange points) these three all cancel out. If you draw a line from moon's center to earth's center, the L1 is about 15.09% of the line from the moon and 84.91% of the line from earth's center. The moon's semi major axis is 384400, so the L1 is usually around 58030 km from the moon's center. inward femoral torsionWebv. t. e.
