List of Earth-like worlds, v2

I noticed an error while making the update: @Steyla , the screenshot for Ooscs Freau ZY-S d3-9468 shows a water world, not the ELW in the system. Could you make a new one?
 
Nothing particularly noteworthy this time, except for maybe DRYOEA BLAO ES-A D1-5754 3, whose atmosphere has an unusually (I think) high oxygen content; 43,4%.

I imagine there could be houseflies the size of eagles on this planet... or spiders the size of elephants :oops:.
Not really. To get higher levels of oxygen available for lifeforms to absorb, it's not the total percentage of oxygen that's critical; it's the partial pressure. While the atmosphere of this planet does indeed have a proportionally high amount of oxygen (43.4%), the total atmospheric pressure is less than half of present day Earth (0.47 atmospheres). 43.4% of 0.47 equals a partial pressure equivalent to 20.4% of an Earth-normal atmosphere - so there's actually even less oxygen available on this planet than there is on present-day Earth. Still easily human-breathable, but the giant aircraft-sized dragonflies of the Carboniferous would quickly suffocate due to lack of oxygen. And that low total pressure would also mean the poor things wouldn't be able to take off and fly - the air wouldn't be thick enough to support them.

A planet with abundant life and a Carboniferous-age level of oxygen in the atmosphere (partial pressure equivalent estimated at around 35%, or one-and-two-thirds higher than current oxygen levels) would not be classified as "Earth-like" by ED - there's simply too much oxygen. Humans start to suffer from oxygen poisoning at levels above 28%. Instead, such worlds would be classified as Water Worlds. I have seen terraformable Water Worlds where the only barrier to habitability is the fact that the planet has too much oxygen.

And yes, this does mean that for the vast majority of Earth's history, Earth itself would not have been classified as "Earth-like" by the Stellar Forge.
 
And now, for a little list of my own, the results of ED7K Sector 3 (Croomaa Sector) - plus one ring-in found while flying from the Bubble to the Upper Core. As usual, posting the list, then some tourist notes and additional pics to follow.

And now, those promised tourism notes:

Enroute from Eagle Sector to Croomaa...

Eok Flyuae
- The greatest barrier to comfort and happiness on this small, hot Group 1 desert planet is the 75 degree axial tilt. The year-length is nearly 2 Earth-years long, so I suspect any colonies would have to be temporary, and migratory.

Croomaa Sector worlds...

JG-O
- This planet orbits a G-class star, and is "out of sequence" compared with the ED7K survey results because I stumbled upon it while making a refuelling stop doing the B/L class survey. It's a typical Group 2 world, perhaps with a "desert island" climate; perfect Earth-gravity match but with a stifling super-thick atmosphere.

CX-A - I happened to encounter this Group 3 (large) hot jungle planet during a Spring/autumn equinox - it was rolling along sideways in it's orbit, with the near-90-degree axial tilt pointing the poles in the direction of motion. At other times in its 5.6 Earth-year-long year, it's a much less hospitable place.

FW-D - A Group 2 world with conditions that are actually quite close to Earth - slightly cooler, slightly thicker atmosphere, nice match for day-length. It's also just one of the life-bearing worlds int his system; if you look closely, there are four other Waterworlds in the system (planets A7, B1, B3 and B5), with the first two of those being terrafromable. With two other terraformable worlds in the system, I would heartily recommend adopting this system as the sector capital.

UD-S - Here we have one of those rather rare varieties of Earth-like: it is Ungrouped (what I call Group 0, or "Outlier"); only about 1% of ELWs cannot fit into any of the three Groups, and this is one of them. A planet with gravity this high would ordinarily be a Group 3 world, but it's cold - and sometimes colder planets have high argon levels, like this one does. The additional 10% argon in the atmosphere has bumped the overall atmospheric pressure up to near-perfect Earth-match, far higher than a Group 3 world usually goes. Environmentally, I would classify it as "tundra".

ZF-L - The first of three from the F-class survey, this world has a two-and-a-half-months-long day, due to being tidally locked to a distant Water World companion; the Water World is terraformable but would suffer from the same tidal-locking problem. Being Group 1, it is small, with a cool and humid environment. If they colonized this planet and you were stuck in orbit due to fog over the spaceport, you might have to wait a few months before the fog clears.

TS-S - Another hot, desert planet, which the current graphical depiction belies, as it looks cool and green down there. It's actually quite a nice planet, apart from the heat. Another lower-end Group 2 world, so the gravity is nice and the air not too super-thick.

CH-M - Another planet down at the lighter end of the Group 3 spectrum, so the planet is heavy but conditions aren't too far from Earth-like. Pleasantly cool, but rather humid; I'd classify the environment as "temperate rainforest".

TY-R
- Another Group 2 world, this one surprisingly chilly. The 12-hour-long day only adds to the uncomfortability.

OM-V - And here's another world that's surprisingly habitable - if it weren't for the heat, it would be highly recommendable. As it is, it's a bit too hot and dry. Group 1.

OJ-I - Some other worlds in this batch I've called "hot". This planet is whatever-the-word-is-that's-beyond-hot. A planet in position 5 around a K-class star should not normally get this hot, but those other two suns in the sky probably have something to do with that. At 319 K, it's just about as hot as you can get and still be officially classified as "Earth-like" and that thick insulating atmosphere probably keeps it at 319 K all day and all night, every day, even at the poles. Calling it "desert planet" doesn't do it justice; I don't think there is a suitable Earth-analogue desert environment to compare this world with. The Dead Sea valley is as close as we get. It's a typical Group 2 planet otherwise.

QS-M - Another large, chilly Group 3 world. The larger-than-normal axial tilt would mean summers would probably be quite pleasant, but stay indoors during the sub-Antarctic winter.

For additional pics, I will be posting them in the ED7k Project thread tomorrow.

@marx : I have also visited most of the other ELWs that are on the List in the Croomaa sector (most of which are Cmdr Clennan's finds from an old neutron farming mission), so if you need replacement/updated system map screenshots of any of them, let me know.

I imagine you have better screenshots than the old ones, so in such cases, sure, please do.
