This is a really really interesting research paper and I can't wait to see it once it is peer-reviewed and finalized! Could the possible Planet X actually exist and is this more evidence of that? Couldnt help but share ASAP!
The researchers calculated that if an object between two to 50 times the mass of Jupiter flew within 20 astronomical units — that's 20 times the distance between the Sun and the Earth — of the solar system's center, it could explain the bizarre orbits we see today.Through computer simulations, the researchers estimate that the probability of this happening is 1 in 100 — which are pretty good odds in this field.
