According to observations during total lunar eclipses, it is shown that the Moon has no natural satellites, the diameter of which is more than 30 meters.
The moon cannot have a long-term existence of satellites. The earth with its gravitational field perturbs high-orbit satellites, and low orbits are unstable due to the presence of mascons. They cause a gradual descent of perilune (the lowest point of the circumlunar orbit).
