[[How do stellar binaries form?]]

usually an agressive motivated vicarious Stellar organizes a small group of supporters who then decide to rule the universe and make them pay dues

Usually it starts with drinks and a nice dinner.

Stellar!

[Tell It Right]

Good stuff.

Now I submit to fellow Freepers a question. How liable are we to find a planet inhabitable by advanced life orbiting a binary star system? I'd submit to you that the tectonic activity on such a planet would render it unsuitable (though we do need a limited amount of tectonic activity). Plus, the ever discussed "goldilocks zone" for water becomes harder to achieve. (Though liquid water is only one of many requirements for a habitable planet.)

Thus I submit to you that the knowledge that most stars our sun's size or larger are binary stars is yet further evidence that a Great Designer made the system we live in. I'm simply not religious enough to be an atheist.

One question being asked right now is whether our own Solar System has a very faint and small brown dwarf star orbiting our Sun at a distance beyond the Oort Cloud. We won’t be able to find out until the James Webb Space Telescope is launched in 2020. If confirmed, that could explain the occasional orbital changes with Neptune, Pluto and the recently discovered “mini planets” even further beyond.
