This ``potential'' to make close Earth approaches does not mean a PHA will impact the Earth. It only means there is a possibility for such a threat.
By monitoring these PHAs and updating their orbits as new observations become available, we can better predict the close-approach statistics and thus
their Earth-impact threat.
I'm more worried about the ones we DON'T know about....
Lol, asteroids or planets crashing into Earth.
I worry more about what I’m going to wear from day to day.
Reason why? I can do something about what I wear, I can’t stop a planet.
Plus chances are it would go quick anyway.
