Astronomy / Space Alpha Centauri is officially no more!!!

You really could not make this up... The IAU has sorted out all the different names of stars in order to end naming confusion. So Alpha Centauri is now actually named Rigil Kentaurus.

It's not a joke... honest.

*looks at calendar*
*looks at calendar again*

You sure it's not April 1st?

**** it. I am still going to call it Alpha Centauri. And Pluto is is still a planet for me. :p

I don't know what all the fuss is about - the star still has the same Bayer designation of Alpha Centauri, it just has it's old name now codified as being the accepted "proper name".
 
I always thought Alpha Centauri was the name of the system, and that Rigil Kentaurus was the name of the α star therein, or the binary system of it and β.

Nope Rigil Kentaurus (meaning the foot of the centaur) was labelled Alpha Centauri by Beyer, the star he labelled as Beta is known as Hadar (I don't know how to pronounce or latin-spell the Arabic).

The binary Alpha Centauri has two stars suffixed A and B, the third star (may be gravitationally bound) suffix C is Proxima Centauri - no historical "proper" name as it is not a naked-eye star but was included in the IAU WGSN list as Proxima Centauri.


P.S. Maybe the thread title should be changed to "Alpha Centauri is officially still there." ;)

Astronomers (and Paleontologists, they're as bad and often worse) should just NOT be allowed to name things. They invariably get it wrong.

I couldn't remember Hadar's name, cheers. Rigil Kentaurus has always been, and is (especially now!) a perfectly cromulent name for Bayer's A.
