“Give example please. you understand Binary stars are the norm?”

Where is our sun’s partner?

[Steve Van Doorn]

We're still learning about super-wide binary stars. Though they're estimated about 50% of all stars similar mass to ours. more for larger stars.

It's hard to tell which stars are binary to ours. two have or will enter the oort cloud that I know about. 70,000 years ago was Scholz star. white dwarf WD 0810-353 will enter the Oort Cloud in 29,000 years.

Though I personally believe the primary star in our system is Sirius which might account for the great year wobble.
This video gives some details of how Sirius might be binary to Sol. Even if Sirius isn't binary it will come close to Sol that we know.
