Looks like we have some new ones to add, care of the IAU's NameExoWorlds project. Some of the relevant details and links can be found here:

If you're wondering about Canada's winning entry:

http://galaxymap.org/dr2/index.html?search=HD%20136418&tileset=SGD&distanceEstimator=bj

From the Nēhiyawēwin language...what we settler-born Canadians of a certain age-range were taught to call "Cree".

All of this remains subject to approval by whatever species we might end up finding calling those planets "home", of course!

22 lightyears away...orbiting a ternary star. All "red dwarf" type stars. From Phil Plait of Bad Astronomy:

Not that kind of bar, though...but this one's interesting in its own right because we live not too far from it, allowing for the distance scale!

Looking at this entry on Wikipedia at the moment:

https://en.wikipedia.org/wiki/Friedrich_Georg_Wilhelm_von_Struve

That's the profile they currently have on the guy whose binary-star catalogue listings got prefixed as "Σ" when cited in articles in Astronomy, Sky and Telescope and Deep Sky Quarterly going back to my teenage years. I don't pretend to know all the star catalogues that have ever been published, and I doubt that I ever will. Even in this age of Wikipedia and SIMBAD.

But, while re-reading My Enemy, My Ally once more, I note that one of the "landmarks" of the story is a system catalogued as "Σ 285 Trianguli". And I find that SIMBAD doesn't really keep track of which stars were known by Struve catalogue numbers these days for whatever reason(s), but if there's a way to nail down which catalogues' listings the star is known by these days...?

Oh. If you're interested, here's the catalogue prefixes that Wikipedia currently knows to keep track of:

According to exoplanet.eu, we are now over the 4000 mark.

4036 exoplanets confirmed, to be exact.

The most recent one had been crashing immediately upon start-up on my other MacBook (Not Pro), so this might be a serious improvement.

Yes, I'm citing Discovery episodes "The Vulcan Hello" and "Perpetual Infinity" here.

The Xarantine Sector-Stack, with Xarantine orbiting Zeta Leporis (per ST: Star Charts)...and I am wondering about Doctari Alpha and HD 38382...?

It's about 83 ly from Sol away per HIPARCOS, 85 ly per GAIA DR2. Spectral type: F8.5V. There *is* a direct line-of-flight possible between HD 38382 and Zeta Lep less than 15 ly...

Trekmapping exercise continued: If we stick with HD 38382 as the primary of Doctari Alpha...

All distances derived from the planetariium-ware program Celestia v. 1.6.1 (2009). I would dearly love to have Gaia Sky working properly on any of my computer gear right now for this...

Sol-Alpha Lupi - 465 lightyears
Alpha Lupi-HD 38382 - 488 ly
HD 38382-Zeta Leporis - 15 ly
HD 38382-Sol - 83 ly

Well, that explains a few things about several people.

Good "previously on..." sequence design and execution.

Interesting that they chose to reduce the distance between Talos and Starbase 11. It makes sense, looking back at "The Menagerie" and its "Kirk and 'Mendez' chase the Enterprise' sequences, mind you, but reducing that distance to two lightyears was still a surprise in the moment to this owner of copies of Star Charts and both editions of Stellar Cartography...

I went and decided to isolate the vertical "stack" of sectors including Vulcan and Andoria using the Stellar Cartography 2nd Edition Federation History map. Check the blue "rectangle" there.

Vulcan-Andor_Sector-Stack

I went digging via whitten.org for possible candidates for "Eridani" and "Azati Prime", and I suspect that I am not searching properly.

I wanted to remember to discuss some of the news about the process of mapping out our galaxy, and the recent discovery that the Milky Way is warped like you might have once done to a vinyl LP. There's a nice little animation that goes some ways in explaining the discovery on YouTube somewhere, but I don't have time to track all the links I'd like to tonight.

More sleep needed, you see.

Talk to you later...

Okay, this is the map I thought I saw in the first act of "Point of Light". I want to say those are Federation Outposts Delta-4 through Delta-8 along the UFP-Klingon border per Star Charts and Stellar Cartography...?

About IC 4996, a star cluster about 6,000 ly away in the direction of Cygnus OB1 and OB3:

https://arxiv.org/abs/1901.11375

"The Streams of the Gaping Abyss: A population of entangled stellar streams surrounding the Inner Galaxy". Looks to be coreward from Sol, from 3,000 to 30,000 ly away:

https://arxiv.org/abs/1901.07566

This one looks more to the rimward side of the Galaxy from Sol. "Ripple patterns in in-plane velocities of OB stars from LAMOST and Gaia":
