Nowadays it's generally thought to be material of various origin that has been shepherded into a ring of debris by Jupiter and the Sun.

Knew that. Personally I think it's too close to Jupiter and too confined for that to be true.

I like, "We don't know yet." It's true of too many 'scientific conclusions' in my book.

It’s based on observation and math, that’s why it is considered true. Unlike the status of Pluto, it isn’t up for a vote.
