How did Madara pull the Meteor stunt? During the 4th Great Ninja War, Madara caused a supersized meteor to fall on the entire battlefield.

How was this possible? The wiki states that he summoned a meteorite, but that can't be true, he never weaved any signs for summoning, or at least the Susanoo's hand seal does not resemble the ones for summoning.

Can anyone clarify how this happened? Is this a Susano'o-only Jutsu? Or is it more like Madara's Sharingan ocular power?
He used the Rinnegan Deva path to pull the meteor out of space. The Deva path uses push and pull so you can push rocks from the earth to the sky making a black moon, meteor, or meteorite thing whatever. He then uses the pull part to crash it down making chibaku tensei. Maybe he pull the meteor towards earth but it would have destroyed his chakra if he did it so he used some of the susanoo chakra to pull of this stunt.
