I don't know what "captured asteroid" means in this sense (though I can't imagine any scenario in which it might conceivably be applied to Pluto). The opinion of the International Astronomical Union is that Pluto is not a planet, because it has not "cleared its orbit". That's not a "hypothesis", it's a fact.


What is Pluto made of?
