Regardless of what I stated, I take no position as regards “Niburu”.

My statement is no more than my speculation of a type of possible “planet” “formation”.

It merely rejects the idea that “all” “planets” MUST be formed (or receive their material) in the initial formation of a solar system (which the main theories believe happens in the cooling of the pre-solar swirling “solar disc”). That theory also speculates as to why most of our solar system has rocky & or rocky + molten cores (heavier for their size) and the majority of the outer planets are gas giants (the gases would have been in greater abundance in the outer reaches of an early solar disc).

I am merely speculating that “capture” might be another means for a star to acquire planets; but that is all I am thinking.

That is basically the plot of the 1933 sci-fi classic novel "WHen Worlds Collide"...........
