I was reading somewhere today that the International Astronomical Union had taken the trouble to organize themselves a body of concerned people to sit down and rename the stars. They did it for the best of reasons; they tell us. They claim that by simply renaming stars it would eliminate the confusion people have who cannot tell stars apart because the spelling is different and that throws off navigators, astronomers, birds and concerned people.
It seems easy enough doesn't it? They have named it Rigil Kentaurus. Nothing could be simpler. All one has to do is change all the text books, all the navigation publications and stellar almanacs, nautical almanacs, air almanacs, star charts, etc and match the old star with its new name.
Space.com shared the name change in its report of 28 November 2016. I'm just a slow reader.
