Why the number keeps changing
Big moons were found centuries ago through telescopes. The small ones, often only a few kilometres across, are found today by long camera exposures on the largest telescopes and by spacecraft. Each new batch is announced by the Minor Planet Center, so the count goes up in jumps. That is why every count on this site carries a date.
