That's also possible. Actually, were it not for how similar the asteroid looked to those he created through Chibaku Tensei later, I'd definitely be pushing that to be the case instead.

The execution and commentary still lead me to suspect it being Chibaku Tensei... Either way, it would stem from the Rinnegan's Tendō, meaning it wouldn't be a Mangekyō Sharingan power. :p
