Newcomer / Intro A way to find all systems [X] Lys from another system?

[Piratescribe]

So, I'm wanting to find ALL systems 15LYs from Nefertem. Is there a way to do this I'm not finding?
That is, an easier way than to click on all the stars I can find on the Galaxy Map that look about 15Ly from it? Besides being tedious, I'm certain I'm missing some this way....
TIA

Not in gal map, but the left panel shows systems in order of closest first.

You can use a third party site for that. tbh, there's not really much call for that in-game.

 

[Ashnak]

Not aware of any third party site that offers this out-of-the-box.

You'd probably have to get a dump from EDDN or EDSM and write your own search routine (or get one of the third party site developers to do it for you).
Problem #1: these sites only have the system data for systems that have been visited by a CMDR running the corresponding feeder app (aside from those at the start where you had to feed the data manually), so you won't get any unexplored systems and miss out all systems that have been visited/explored in-game, but not by someone feeding data into EDDN/EDSM
Problem #2: there will probably very few (my guess: zero) systems at 15.000000 ly from any given system , so you'll need to specify a search interval

OMG duh! Of course! That's perfect and exactly what I was looking for LOL
The ONLY downside is you have to be in the central system in order to create this list -- which is fine for my current purpose, I'm there. But for the future, if I want to investigate the systems X distance around another, I'd have to go there first. shrug no big
Thanks for the tip!!

Thanks, I appreciate your doing the work and giving me the info! But was looking for a HOW to do it, sort of being taught to fish, not given a fish, know what I mean?
Someone gave me a clue-by-four to the head and reminded me of the left-hand nav screen filtered for systems which works perfectly in this situation.... (although, if in the future, I need to figure out a wider radius than that can list, or need to come up with the list without actually going to the target system, this won't work. But I'll worry about that then if it comes up)
Thanks!

No problem, it took only a few seconds. I have a program to do almost exactly this from anywhere in the galaxy.
Done almost as described by Ashnak above, but in the bubble almost every star is in EDSM.

https://www.edsm.net/ ? I looked there to find a way, and am not seeing anything that looks helpful. How do you get this list there?
If you can just point me a general direction, like what (sub) tab it can be found it, I can try to figure it out from there...

The easiest way to do this is by using the "Nearest Stars" table in EDDiscovery - you can set min and max distances etc:

WHOA! Holyhannah that's EXACTLY what I was looking for! It's perfect!!
Yeah, no I have EDD and I looked at it first thinking it surely would have a way to do what I need... but that "Nearest Stars" section on mine was collapsed down under the "Log" section so I never saw it! Not until looking at your imagine, did I maximize it and was able to drag that pane up to see it!
Absolutely perfect!! Thank you!!
Cheers o7

Inara also has the function to view closest systems/stations to (click on the Star Systems tab at the top and then start typing the name of the system in the Nearest Star box until the drop-down of the correct name appears and click that).

EDDB has it also, use the same method in the Reference System near the bottom, then click the Distance LY(^v) on the far right of the list.

It is a shame ED doesn't have a "Show by Distance" where Population is, with a similar slider but showing LY in the GalMap.

OH! The Inara method is perfect! And I don't have to have visited the center system in question first (like it seems like you must in EDD's "Nearest Stars").
Can't seem to figure out the EDDB way, but that's OK, Inara is perfect!
Thanks!!

Ooh nice, that's a handy one too!

Third party sites all have the usual drawback: if no-one using that site has ever visited a system, then that system isn't in the database and invisible to your searches.

This won't make a big difference when searching systems in or near the bubble (as in this case), but if you're out exploring or looking for systems near a remote target, then forget it. Using the in-game tool is the only thing that will work out there, and only when you're actually at the system in question.

Re: Nefertem. I assume you're trying to find some clue as to the origin of the signal that caused the mass psychosis on board the generation ship Thetis. Three points:

1. You won't need to search the entire 15 LY radius. The Thetis was, almost certainly, travelling in a straight line or near-straight-line from Sol. These generation ships were travelling at 0.2 c and a ship travelling that fast in normal space doesn't change course easily, and won't change course at all once it's dead or running on autopilot. It won't have reversed direction. So the prime cause, the "uninhabited planet they passed 15 light-years ago", is going to be somewhere not far from the straight line between Nefertem and Earth.

2. We do not know exactly where the ship was when the incident occurred, but it wasn't in the Nefertem system. We have some clue, thanks to the timeline mentioned in the logs. The logs mention the "very first ninth-gen child born on ship". Assuming that the first "second-generation" baby was born shortly after launch and those eight subsequent generations of parents were all in a hurry to procreate and had their kid when they were about 21 years old, then the event happened about 168 years after launch. Travelling at 0.2 c, that's 33.6 LY from Earth when the incident occurred - the Thetis must have travelled on, dead and empty, for another 20 light-years before finally stopping at Nefertem. The "uninhabited planet" must then have been 15 LY closer to Earth than that 33.6 LY event point, or only 18.6 LY from Earth.

3. The Thetis story is a "work of fiction", written by FD's story-writers who probably had no idea where their Thetis story would be placed in-game and as such, was not designed to be picked apart for clues to an actual origin of the death-meme message. I doubt anyone in FD actually did the above calculations and worked out "yes, in Year 168 the Thetis was here, and the message was sent from there.".

Finally, 15 LY at 0.2 c is 75 years. That's a long time for a death-meme to be lurking in the comms system before escaping.

Ah! All excellent points! A little disappointing, was kinda hoping to maybe figure something out. But then, I'm not even fractionally clever enough to have solved the ADAMASTER ghost ship puzzle, so anything I'M capable of figuring out surely a few thousand other players would have figured it out first and it'd be all over the boards, heh

But if one does have one's heart set on finding the source system, then using my above logic, there is a candidate. Looking at the ED starmap, there's really only one good star system that meets the criteria (about 18 LY from Sol, and roughly in line with Sol and Nefertem).

Gendalla.

It's also a "good system" to fit the description: "uninhabited". It's certainly uninhabitable from a gen-ship point of view, with no terraformables, just a bunch of super-hot dragon-spittle worldlets and a chilly ice giant with a string of ice moons.

Under this logic, the Thetis must have been somewhere in deep space just beyond the Abrogo system when the incident happened.

Wait, what? From what I can tell (unless I've misunderstood any part of this, which is very possible), Gendalla is about 36LY from Nefertem, where the "Thetis" is currently drifting. From what I understand, they encountered the strange signal 15LY from their current location (Nefertem?)... not 15LY from their departure on Sol. Right?

No, it was 15 LY "behind" wherever the ship was when the incident occurred. Which, as I said, was almost certainly not where the ship currently is located. The ship didn't suddenly stop dead, just because everybody on it died. It would have kept flying.

Here's my rough timetable of events.
Year 1: Thetis launches from Earth, in general direction of Nefertem.
Year 93: Thetis passes near Gendalla, doesn't stop but somehow picks up death-meme message, which is stored in the comms system.
Year 165: Thetis passes near the three starsystems of the Abrogo Cluster. Doesn't stop. There's a huge, star-less void between Abrogo and Nefertem.
Year 168: Thetis log events: death-meme escapes comms system and infects ship. Event happens in deep space while ship is still travelling at 0.2 c. Everybody aboard ship dies within a year. Ship continues outwards at 0.2 c, on autopilot.
Year 267: Thetis, now a ghost ship, arrives at Nefertem; autopilot decides to stop ship in Nefertem, despite lack of colonizable planets.

The events at 93, 165, and 267 are fixed, set by the cold equations of physics of where a ship will be when travelling in a straight-ish line between Earth and Nefertem at 0.2 c. The only variable is the actual infection event that I've put at 168; it might have happened later, if the crew were slower to procreate than I predicted. But if the "first ninth generation baby" didn't happen until Year 267, that means the parents waited until they were (on average) over 33 years old, which seems unrealistic on a ship that's specifically designed to be baby-powered.

The only other alternative theory is that Abrogo itself (or one of the other two starsystems in the Abrogo Cluster, being Yin Sector GW-W c1-26 and LHS 2149) is the source of the death-meme message, meaning the message was encountered somewhere around Year 165 and the event happened in around Year 240. Which I would deem unlikely, due to the same timing problem I mentioned above - the "generations" would have had to have been 30 years apart.
