I have done more updating to the table "Known-(with reasonably low uncertainty)-NEO-Earth-Close-Approaches-Less-Than-10LD(Nominal_Dist)-as-of-2019-11-08p"


I added
  • Planetary Orbits -- Scale Model
  • Solar System Objets -- Scale Model
Planetary Orbits [if the Earth was the size of a Basketball - with a radius of 12.0275 CM(4.73523622 inches)]
Planetary Orbits [if the Earth was the size of a Basketball - with a radius of 12.0275 CM(4.73523622 inches)]
Solar System Objets
[if the Earth was the size of a Basketball - with a radius of 12.0275 CM(4.73523622 inches)]


If  the Earth was the size of a basketball  how far would the Moon [and the NEO Earth Close Approaches  be]
If  the Earth was the size of a basketball  how far would the Moon [and the NEO Earth Close Approaches  be]?  Here is a spreadsheet of 9331 Close Approaches Less Than 10LD (Nominal_Dist) as of 2019 11-08p   [if the Earth was the size of a Basketball - with a
  radius of 12.0275 CM(4.73523622 inches)]

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.
