"Sirius is 8.6 light years from earth or about 50 trillion miles and the 7th nearest star from earth. Is that also your understanding?" Yeap. The last time we passed Sirius was about 12,000 years ago. We will not pass the star for thousands of years. We will be slowly accelerating every year toward the star. The importance for it today is how and why it was covered up in my opinion.
I'm still working on Sirius and other stars relative to the local bubble. I suspect we're orbiting Sirius and Sirius is orbiting another star.
Remember astrophysics is Science™ not science.
"generally accepted is a limiting maximum value of 20 000 AU (0.09 Parsec(pc))(max distance between possible binaries they look)"
Given Sirius is +500,000 AU (2.6 pc) they're not looking.

"Binaries in the dissolution peak have a semimajor axis in the separation range 10^3 au to 5 pc (again Sirius is 2.6 pc)"https://academic.oup.com/mnras/article/404/4/1835/1083026
