Sirius has a proper motion of 1.2 arcseconds/year in declination and .546 arcseconds per year in right ascension (15 km/sec and 6.8 km/sec velocity relative to our solar system respectively). Since we're about 8.6 light years from the Sirius system, and since Sirius A and B have a combined mass of nearly 3 times the sun's mass, the escape velocity from the Sirius system at the distance of our sun is about 0.1 km/sec. In other words, our solar system is traveling many times too fast relative to Sirius to be able to orbit it or be in a trinary configuration with it.
very well said!Astromut!
Quoting: Trample We once thought there was no Sirius B--simply because it didn't seem plausible due to the data we "adopted" prior to the speculation as to whether it existed. Actually the existence of Sirius B was predicted by Friedrich Bessel due to changes in A's proper motion long before B was even detected. The Dogon, however, knew it was there for hundreds if not thousands of years before we were able to view it through a special telescope.
Quoting: secondI disagree. It doesn't seem they actually knew it all, in fact.
