Good points, both of you. However taking Mausa’s math as correct, if the last time this “Planet Nine” was 200 AU’s from the Sun, it knocked (via its gravity of course) a comet or asteroid on our way to us, such a killer could indeed be only weeks away. This is because the scientist in the article believes it is at that distance (200 AU’s) where Planet Nine may knock a Kiaper Belt object towards us.
The real math would involve determining when Planet Nine was last at perogee with respect to the Sun. Then, from those dates, determining when we are in the most danger of being hit by a rogue body sent by that planet by adding 23.7 years to the last date Planet Nine was at 200 AU’s from the Sun (and thus in the Kaiper Belt region).
I assume that’s what the “some” described in the article did when predicting our doom “as soon as this month”. Who knows though.
