At the risk of sounding like an *** (not my intention):

There are a crazy number of ELWs. EDSM has (as of this writing), 33,400 total ELWs in it's database.

Have you considered talking to EDSM's Anthor about reading from that database and writing into your own, instead of trying to maintain a spreadsheet that seems to be getting pretty massive?

Well, technically I didn't consider talking to Anthor, but of course I considered using crowdsourced data. The trouble with that is that the journal doesn't record everything that this list does, which is no surprise, seeing that the list predates (pre-dates) the introduction of logging by quite a while, and we had only screenshots to work with. Although the planetary data is now fully included in the scan events, some system data and of course screenshots are still missing. So, the log data would have to be in a separate sheet.

I did make such a sheet which you can find here, but to be honest, I don't really see the point of making it update automatically.

This list is still here for those who'd like to keep track of their discoveries easily, and to be able to search for the more rare discoveries without having to trawl through a large database, but I'm not really interested in going out of my way to get new entries to it, be that through automatic updates or advertising the thread. As far as I'm concerned, crowdsourced data has supplanted this for most purposes, and I'm fine with that. But for those who'd still like their finds to be added here and take the effort to compile them, I'll still keep it open.

Besides, while the spreadsheet is pretty massive by now, it's not like it sees a lot of traffic these days. So maintaining it is not much trouble.

Hi! I found a double earth-like planet orbiting around their common center of mass. Is this a worthy candidate for the POI on galaxy map?

Howdy! I can't speak for the GMP, but I can tell you some numbers. You've found some binary Earth-likes, which are rare: out of almost ten thousand ELWs on this list, only 315 them are such. (A few are missing screenshots of the second Earth-like, hence why it's an odd number.) So a bit over 3%. Plenty of Commanders would have liked to find such a thing, but personally, I don't think that a binary Earth-like would qualify as a POI on its own. The only way to know for sure would be to ask them, though.

Trinaries, on the other hand, are exceedingly rare, with only 9 (so three pairs) having been found so far - that I know of.

@ HMZS: Welcome, and thanks for using EDJP! However, as mentioned in the first post, screenshots are required. Please upload them somewhere (most use Imgur) and add the URLs to your submission, and then I can add these to the list.

do i have to put the screenshots _with_ my discoverer name on it ?
Click to expand...
If you made the screenshots before you turned in the data, and your name isn't visible on it yet, that's fine. No need to make new screenshots for this.
You can also submit Earth-likes that others have discovered, by the way. They'll be listed as the discoverer, and you as the contributor.

HMZS said:
also, how long can i edit the post before it gets locked ?
Click to expand...
Hm, no idea. As far as I know, no threads get auto-locked here, so... at least a couple of years?

I usually take a screenshot when I discover it as a reference, then go back and take another one once the data has been turned in (while unlikely, it's possible that another cmdr could come along and scan the same system and turn the data in before you).

I've recently returned from my work enforced ED sabbatical and have embarked on some minor engineering on my AspEx in the hope of improving the jump range from 51Ly Max, to hopefully push that out to nearer 55Ly.
Anyway, I decided to take a look at the list and what a shock I got when I looked at the Data Error sheet!!!! Holy cow I cleared most of that down 4 months ago. Looks like I have some travelling to do once more.

Hey!

I am new here and it is my first list of ELWs and now it contains 25 ELWs, including one Binary ELW and one ELW is satellite of another planet. If I did something wrong when writing the list, correct me please. Thank you! (I apologize for possible mistakes, I do not know English well)

@ Klepto: Welcome, and thanks for using EDJP! Don't worry, your submission is almost perfect, I would just have preferred it if yo put the URL's text into the URL field, and not as a link. But that's something that I can easily correct.
More importantly, you seem to have come across something very rare, an ELW's moon that has active volcanism. Could you post a screenshot of the moon, Oephaif SY-C b57-0 1 a, please? I'd very much like to see exactly what kind of moon that is, as it could be quite the rare outlier.

@ jimbeau: Welcome back! Personally, I'd only recommend going after any of those unless you're headed in that direction anyway. But it's up to you to decide, of course. Also, there's no need to go for the ones that Johnny Frost co-tagged, as he's currently re-uploading the screenshots for those.

@ Spacecat: Yup, it's unlikely, but it has been known to happen. Especially for Commanders who have been out long.

It's also around an M class, for extra rarity (as are a few of the others). (And "moonwith" highlighted the fact I missed a space in the generated description...)

I don't think I'm too far from that system, might pop there when I finish what I'm doing.

Thanks for the moon screenie! Yep, that confirms the volcanism (I was a bit afraid that a journal error might have had it wrong), and it's really quite interesting. The only other three ELW's moons that have volcanism are all in cases where the ELW is a moon in orbit of another parent body, and as such, its own moon is orbiting it very close by. In these rare configurations, there appear to be enough tidal forces for volcanism to pop up on the moon. Your find is special in that it's a moon of a regular Earth-like. I'm not sure how closely it orbits the parent, but it looks like the ELW itself orbits the class M star (already quite rare!) close enough by that this would pop up.
I'm not sure exactly how rare this exactly is, as we don't have data on most of the moons in such systems, but it's probably very rare. Personally, I'd recommend posting it as a candidate to the Galactic Mapping Project.

Oh, and the same goes for your friend's trinary ELW system. Those are incredibly rare themselves, before this, we only knew of three other sets. I don't suppose you have screenshots of the remaining two ELWs in the system?
