I read that as Paris. On the plus side it makes more sense now. Should probably go to sleep...

I also read Paris, and thought "stars" referred to celebrities. Oops

That is literally the exact thing that I thought too. Its interesting that a sentence like this can be so easily misinterpreted by multiple people in the same way.

Could Jupiter have been a failed pair?

Well what do you know, Jupiter doesn't actually orbit the sun! Not properly anyway http://www.iflscience.com/space/forget-wha-you-heard-jupiter...

This is silly semantics. Jupiter and the Sun both orbit the center of mass of the Jupiter-Sun system. The article is making the point that for Jupiter and the Sun this point happens to be just outside the surface of the Sun.

It's much simpler to say "Jupiter orbits the Sun" than "Jupiter and the Sun both orbit the center of mass of the Jupiter-Sun system". You can think of the former as a shorthand for the latter.

But doesn't this show that the main players of the solar system are the sun and Jupiter?

Apologies for the source, and my clear lack of knowledge in astronomy.
