<p>Instead we can make a list of stars, and <em>name them systematically</em>. We could use the part of the sky that the star appears in, and some letter or  number.

When we do this we get "names" like "omicron ceti" (using the letter "omicron" and the part of the sky "ceti")
or "HD 128621" (star number 128621 in the list prepared by Henry Draper). or WISE 0410+1502 (a brown dwarf discovered by the Wide-field Infrared Survey Explorer, and located at 04hr10min, 15deg02min in the sky)</p>

That is precisely my point - those nearest stars are exceptional. If for nothing more - just by the virtue of being our closest neighbours. And as I said - I have nothing against keeping catalogue based names (or other systematic names) for those thousand or so stars within 50 light years. But maybe those listed on the Wikipedia list I linked already merit an unique name more than hundreds of obscure asteroids of the Solar System that have been granted one over the years. And BTW, I don't consider names in the vein of Barnard's Star or Kapteyn's Star to be sufficient either

I know professionals don't mind their professional designations. I'm just dumbstruck they seem to don't see any value in granting those lowly peasants who "read about discoveries of things like exoplanets" this little thing that they positively know so appeals to them.

After following @barrycarter link I know it's not entirely true. Professionals do seem to see the above mentioned value - hence the NameExoWorlds campaign. It just seems they need a lot of time to come around to actual naming and that we're in dire need of quickly establishing another campaign - maybe this one should be called NameStellarNeighbourhood?

This is pedantry, I know, but you said " the brightest star in the constellation Canis Majoris"; this should be " the brightest star in the constellation Canis Major". Canis Majoris is the genitive form of the name, so it means "of Canis Major".

As a complement to @JamesK’s excellent answer, I would add that even existing star names are mostly descriptors rather than names, but taken directly in Arabic instead of translated. For example, Deneb, the brightest star of Cygnus, is an Arabic word meaning “tail,” referencing its position in the constellation figure. Same for Betelgeuse, a corruption of the Arabic sentence for “the shoulder of the giant.”

# Why nobody cares to give the nearest stars better names?

(Asked by: username_0 on 2017-11-26)

The star occupying 6th place on [Wikipedia's list of nearest stars and brown dwarfs](https://en.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs) can be called either **Lalande 21185**, **BD+36 2147**, **Gliese 411** or **HD 95735**. That seems to me like a fine, quadruple choice of equally bad names.

I mean, I know these come from positions held in various star catalogues and maybe aren't that bad compared to monstrosities like **WISE J085510.83−071442.5**, but can't we keep those for stars like 50 light yrs away and invent something better for our *nearest neighbours*?

This year we saw a [batch of confirmations](http://www.drewexmachina.com/tag/nearby-stars/) for planets orbiting in habitable zones of many of these stars. In not so distant future we may find ourselves discussing possibility of sending probes to some of these systems. Aren't better names long overdue?
