Yes, bump. You gotta watch that one, really. The best youtube video ever. He goes one further and amongst other things shows that not only does our sun travel the milky way as shown in the original video but that our sun travels around a larger sun and it also around a bigger sun and that they are going to allll line up in a giant cosmic conjunction on 12-21-12. I'm on my third viewing of this one, it's so fascinating. Wow, filling your head with more crap are you? 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. Oh and they mentioned Alcyone too, didn't they? Let's crunch the numbers for that as well just to show you how ridiculous this is. Alcyone is of course part of the Pleiades as well, so let's use the total mass of the Pleiades cluster to see if we're orbiting it. Alcyone has a parallax of about 8.09 milliarcseconds, which corresponds to a distance of about 402 light years. [ link to simbad.u-strasbg.fr] It also has a proper motion of about 19.34 milliarcseconds in right ascension and -43.67 milliarcseconds in declination per year. Now at a distance of 402 light years, those 43.67 milliarcseconds/year in declination translate to 805,195,033 kilometers per year or about 25.515 km/second. Now the Pleiades cluster has a total mass of about 740 sun masses ( [ link to arxiv.org] ), so at a distance of 400 light years, the escape velocity for the entire Pleiades cluster is about 0.227861 km/second. In other words, even just taking into account our proper motion in declination, to say nothing of our total motion relative to Alcyone including in right ascension and radial velocity, we're traveling over 100 times too fast to be orbiting the Pleiades! We are not "going around" Alcyone, the claim is ludicrous crap! Gravity - the weakest force in the universe. So many conditions. :)
