List/Graph "11 = All NEOs Closer than the Moon:..." in Folder "C = Close Calls nearer than Moon:...":
2019 is the record year! Also notice when it started to increase...
As you can see above, in 2019 we had
82 close encounters with such objects (the ones we didn't detect, not even mentioned here!). That means that
in the year 2019 an object like that flung very close by earth on average about every 4.5 days! Now, compare this number for example with the year 1991, which was the year in which the first ever object of this kind was discovered/detected. In 1991 only 2 objects of that kind flung very close by earth. Which means that in 1991 an object like that flung by earth on average "only" about every 182.5 days. Or take a look even just at the year 2006 for comparison above; there were still "only" 6 such objects discovered/detected.
Now, how many of those 82 objects in 2019 were discovered ahead of time and how many after the close approach already happened? If you arrange/order the list accordingly, you will see:
54 Objects were discovered on the
same day or too late, which gives us roughly
65.85%.
28 Objects were discovered
ahead of time either one day before or earlier, which gives us roughly
34.15%.
However, out of those 28 Objects 12 Objects have been discovered just 1 day before, 4 Objects two days before, 6 Objects 3 days before, 1 Object 4 days before, 1 Object 6 days before, 1 Object 9 days before, 1 Object 10 days before, 1 Object 11 days before and finally, 1 Object 13 days before. And that's it.
So, if we are in a really generous mood and say that we could have done something to protect or prevent the earth from being hit by those Objects in 2019, that we detected a week earlier and above (7 - 13 days), then we have to say that in actuality we couldn't have done anything about the remaining 24 Objects out of those 28. Which would mean that
we couldn't have done anything against 24+54 Objects out of those 82 Objects, which gives us roughly a sum of
95.12%.
But, I would dare say, that we, realistically speaking (with the capabilities at our disposal nowadays) couldn't have done even a darn thing against that object that was discovered 13 days before. So that means, sobering enough, that
100% of those 82 Objects in 2019 would have hit earth without us having the slightest chance to do anything about it, since they all, without any exception, were discovered much too late and thus that we are basically screwed against the power of the cosmos!
And in case you are wondering if 2019 was an exception in that regard or if we have been improving (detecting things well ahead of time) since 1991, I'm afraid to have to disappoint you'll with "bad news" here too. 2019 was not exception and it pretty much looks that this sobering ratio doesn't improve at all over time, in any shape, form or fashion.
