The branch of the EML2 Halo orbit stable manifold that extends toward the Moon. Unlike the right-pointing manifold which extends away from the Moon, the left-pointing stable manifold asymptotically approaches the Halo orbit in backward integration and moves along the Earth-Moon line toward the lunar side in forward integration, eventually reaching the Moon's vicinity. It is the key orbital structure for low-energy transfers from lunar orbit to EML2 Halo orbit
