ELW bucket list

[Erratic Spawn]

It's not unheard of, but some of the similar ELWs close-in on M-class stars like that are hand-crafted. Here are the top 25 from the EDSM data, where the ELW directly orbits a star (so this excludes ELMs, unless they orbit a brown dwarf or something like that):

mysql> select planets.name,planets.distanceToArrival,stars.subType from planets,stars where planets.parentStar=stars.id and planets.subType='Earth-like world' and planets.distanceToArrival is not null and planets.distanceToArrival>0 order by planets.distanceToArrival limit 25;

Thanks for the answer. I see you ran an SQL query to get the info, so this info is not easily available. And it is obvious that these are all very cool stars, though #1 with 7 ls sounds really amazing. I'll pass the information on to my friend with the surprising insight that 23 ls is close, but does not even make it into the top 25. I didn't expect that.

Actually, it is: you can refer to the Earth-like worlds spreadsheet of the processed EDSM dumps on EDAstro... which is made by Orvidius.

Also, to answer your earlier question: yes.

Okay, good to know for future references. I knew the website, but did not realise that such information would be available there. Also thanks to @Orvidius on behalf of Cmdr MetaChristmasMauvais (on Xbox) who asked the question originally on the expedition Discord channel.

Now I guess this one I just stumbled across must be in the very rare category.

ELW orbiting MS class giant.

Primary star 13b years old, this ELW must have once been a frozen popsicle orbiting and M class and got thawed and developed life after it expanded, however it's probably not going to last long as an ELW where it is.

Identity obscured until I get back to report it to a UC branch somewhere.

 

[marx]

Yep, carbon star. Very rare, and they give a nice green tint to the planet too.

 

[Erratic Spawn]

A quick question to the experts. I discovered an ELW today, which had a distance of some 1,900 ls from the star. Now I bashfully admit that normally I do not pay much attention to such details, but that distance seemed rather large even to me. So I checked EDSM and it defined the Habitable Zone somewhere between 600 and 1,400 ls. This ELW is 500 ls beyond that, yet the surface temperature was about 300 K instead of the expected frozen planet (the polar region looked normal as well).

So the question: How consistent is the Stellar Forge in adhering to the correct placement, i.e. is such a discrepancy quite common, or is it something that should not really exist? I mean the most important factor of the habitable zone is the physical possibility of liquid water, which the ELW clearly had, yet the position did not match.

Judging by the EDSM range would presume the ELW is orbiting an F star but is there a secondary star in the system?
Extra stars will add distance for the habitable zone- sometimes by a fair distance.

Thanks for the quick answer. Your assumptions are correct. I have added the images (system name redacted) for reference. I guess then EDSM is not considering the additional stars when estimating the habitable zone (unless that value comes from somewhere else and EDSM only displays it).

Spoiler

Yup. We know the habitable zone pretty accurately for single stars, secondaries move it by more than we think they should and the model hasn't been entirely worked out, as far as I am aware. Also EDSM doesn't necessarily know that it's system information is complete so trying to take account of other stars could end up being misleading.

Does this count as a "GFL" find?
Ringed Earth-like orbiting a T-Tauri - from the list, I note that it falls in the "Common" range because the star is an A-type - but the other conditions are... I'm not sure where it would fall in the list...

Bit of a clarification: while the main star being an A-type is common, yours is an ELM orbiting a T-Tauri star, which in itself is already in the GFL category. Then it's also ringed. The planet being the only planet in the system is rare, just not sure how much - but at this point, it doesn't even matter.
So, congrats on your find!

Ah, thank you for clarifying!

 

[Martin Shepard]

Hey there! Found this yesterday. Can anybody say how rare it actually is as it meets multiple criteria?

 

[JonathanBurnage]

Looks pretty rare to me. Not sure what type of world it is orbiting - please can you translate for us anglophone monoglots?

 

[marx]

Doesn't matter that it's in German: the screenshot shows an Erdähnliche, I mean, Earth-like world, not its parent. With no system name, and only a guess that it's AB 3 a, it's a bit difficult to tell. Parent is either a HMCP or a HMCPTC: I find the latter less likely, but with this star configuration, it should be possible.
But depending on how the various factors are, it should be either in the Rare or the Very rare category.

It's a HMC, non terraformable. And yes, it's AB 3 A.
This system is actually pretty cool as there's also a terraformable water world in binary orbit with a terraformable HMCW. Would be a really nice outpost for humanity out in space

I have a question about ELW's that may as well go here as anywhere else :
Some "ELW"s have an axial tilt close enough to 90deg - many exceed 45deg. How can these worlds ever be regarded as "earthlike"? Their seasonal climatic variations would be so extreme that I can't imagine how they could remotely resemble Earth. Orbital distances, temperatures, chemical compositions etc seem irrelevant to classifying a 90deg-tilt planet as an ELW under those circumstances.
Maybe Stellar Forge parameters should be changed to exclude high-axial-tilt worlds from the ELW category? Just thinking out loud....

 

[iain666]

Human breathable atmosphere makes an ELW. It doesn't have to be like earth in any other way, so long as we could disembark our spaceships without breathing apparatus it's in.

OK, if that's the only criterion. Makes no sense to me though, if you could breathe, but immediately got zapped by that day's mega-hurricane or super-tsunami weather event.
Such a world probably could never be terraformed to become human-habitable. I guess that's my main point.
Thanks for the quick reply!

 

[firmicute]

so, just found a system with 3 ELW and a water world. mine initially, but the system is 15 mil crefits worth, so if anyone is near the center, have fun.
it also is a system where a m orbits around a neutron star, both are orbited by a m star with said 3 ELW& 1 WW

CROOMOI CV-Y D2590 12 bodies, 3 ELW, 1 WW 2 hmcs & 3 rocky moons
neutron star& 2 M


some other ELW containing systems that are a bit unusual
DRYOI BLOO TC-C ELW, 3 WW, one WW orbits around the ELW. F
PHROI FLYA NJ-F D12-995 1 ELW & WW orbiting around each other A
