Hi Bill,
Don't know if MPML is still operating, so figured I'd just send this your way since it's
of more potential interest to you than most. This object is probably either lunar
ejecta or manmade. Mean motion nearly the same as that of earth, low inclination,
and low eccentricity. Earth encounter velocity must be very low. --Rob
