Another fascinating article... thought I'd share it here.
Jupiter is the oldest planet in the Solar System
Jupiter's ancient name really is well-deserved: according to a new study, the king of the planets isn't just the largest in the Solar System, it's also the oldest. A team of researchers from Lawrence Livermore National Laboratory in California and the University of Munster in Germany have determined that Jupiter's core was already 20 times the size of Earth merely 1 million years after the sun took shape 4.6 billion years ago. Since newborn stars tend to release energy that blows away gas and dust for planet formation, the gas giant must have had to absorb materials very, very fast. (Excerpt from the article)

@Urses: I remember, as a child, watching NOVA and there was an episode with Carl Sagan - I was in middle school at the time. Anyhow, he made it clear on this particular episode that Jupiter had everything needed to become a star - except the nuclear reaction in it's core. Then a few years later, the movie 2010: The Year We Made Contact came out - and within that movie (and I should add the book it is based on), Sir Arthur C. Clarke actually used that in his book/story - Jupiter became a star!
To answer your observation, Yes, it is plausible. But what if as the solar system began to stabilize, if Sol's (the astronomic name of our sun) binary partner was tossed out of the system as Jupiter coalesced into the dense body we know it as today?
