NEO Earth Close Approaches within 25 Lunar distance(dist_min)

We getting better at finding NEO(s) however we have not been looking for very long. Many factors like the full moon, cloudy nights, the lack of large telescopes(i.e. poor sky coverage), etc can keep us from discovering them. So, therefore, we do not "know" about many of the Close Approaches that have happened.  Much of the "known" Close Approaches is only our best postdiction and predictions  Here is An  NEO Earth Close Approaches within 25 Lunar distance(dist_min) table [ Data was taken from NASA JPL SBDB Close-Approach Data API on 2019-10-14.] and scatter plots.  The apparent gaps are most likely were "unknown" Close Approaches would go.
