There are very few stable orbits close to the lunar surface. Basically a couple of polar orbits with very specific parameters, and that's it. The rest get so perturbed by gravitational anomalies that they fall out of orbit after a few months or years--faster than low Earth orbit where there is atmospheric drag! https://www.lpi.usra.edu/lunar/documents/NTRS/collection2/NASA_TP_3394.pdf https://www.lpi.usra.edu/lunar/documents/NTRS/collection2/NA...
