The Future of the Solar System

Bob Greene: Hallea did not just sweat it out and endure the heat. This is what our sun is going to do in about six billion years. He says one theory is that such a hot Jupiter was created at the outskirts of the solar system, then kind of migrated in really close. The researchers believe that this is not a viable option. They say how fast the changes would have been happening to the parent star. That's not really an option. Another theory is that Bektu was in fact a binary star in its past. And we just don't know a lot yet about all the different ways that planets and binary stars evolve together.
