       Milky Way's fastest star orbits our supermassive black hole so closely it feels its spinDuring its closest passage to the black hole, the star travels at around 25 000 kilometres per second or over 8% of the speed of light — making it the record holder for the fastest star in the Milky Wayhttps://www.eso.org/public/news/eso2612/#S301 #ESO #MilkeyWay #SagittariusA

       @stux I think it’s a recognized notion of orbital mechanics that if a fast moving object is actually revolving around an object almost everything else is revolving in the same plane and the orbital center is itself revolving, because anything going the wrong way is flung away it cancels itself out. It’s why planets have rings, and planetary systems are mostly sharing the same approximate plane.
