Our Binary Star

Found some information on Earth's peoiodic orbital changes.

And yes, I think Barnard's star is way too far away.

It would have to be a red or black dworf star to not be easily noticed.

Interesting.  Seems due to Jupiter and Saturn's gravitational pull?

Some facts to fit Barnard's star to the Suns binary companion.

Rough calculations give it around 180 km/s average speed for stated 24000 year period applied to Barnard's star. It is measured at about 142 km/s but is moving away from the Sun at 110 km/s so it is not getting nearer. This rules it out for where the binary star would be in orbital travel.

Next candidate please.

Not impossible that our sun once had a companion, but it certainly doesn't today and definitely not Barnard's Star.

Considering 85% of star systems are binary or trinary, the odds we are a singular system, is minimal. 

We also must consider the duality of our reality. A binary system would fill the voids.

It's 25,920. 

Additionally, I do believe we are in a binary system. However, scientists have not identified our sister star. Do you know what it is?

It's the mighty 'brown dworf' Urectum! But astronomers hated that name, so they scribbled over it with a black felt-tip marker. Now, they secretly whisper about it to each other as Neu-Biro.

... Just so they wouldn't be embarrassed and keep explaining about all of that 'poo stuff' about our biology at all those intergalactic astronomy conventions.

It also means they don't have to mention those resident Anal-narkys, who went about pretending to be god-like but who froze to death when their dark 'brown' star (there's a scatological theme here) got too far away from Sol.

There is no reason ever discovered to think we are currently in a binary star system.
Like I said, it's possible that our sun once had a companion, but there's not one today.
If there was one, no way can it be Barnard's. It has the wrong trajectory through space to have come from nearby us. Simple as that.
