Earth like Worlds

Yeah, NASA possibly found one, but is it really an earthlike, or is it a water world...or a metal rich/rocky with a water atmosphere? Hard to tell from this distance...

How many are there?

This would suggest that we should find one every 400 sys scans or so.

I think I've been to 6,500 systems and have found 3 so far.

Then you are not a good explorer :), or, rather, are exploring in a manner that does not facilitate finding Earth-Likes. About 1 in 100 is my score. I am 1118 systems into my current journey and have 12 E-Ls (plus 17 AWs and 115 WWs).

I'm getting a better-than-1-in-100 rate, I think. Focusing on A, B an F type stars seems to help with the odds a bit, but really, the real difficulty is slowing down and checking the system map for ELWs in the first place...

I have 7 tagged so far
and one that i found on my current journey into the black...hopefully remain untagged by the time i get back & sell the data
plus COUNTLESS terraformable water worlds
and i'm not a big explorer...just little 1-2 day trips 1500ly out or so. most of mine are within 500ly of Sol. Never even been further than 1700ly out.

there is a method for finding untagged Earth-likes:
go to where the galaxy is less chaotic, away from the core, the O-types, T-Tauris, nebulas, neutrons and black holes.
and away from where the common routes for explorers (ie, not directly to the core or big nebulas)

head out at an angle from populated space, away from any major targets, steep on the Z-axis until it starts getting sparser (800-1200ly from the central plane)
use fastest route to get there, then filter out everything except A, B, F, G, K and plan little routes of 5-10 stars on economical, hitting as many as you can per go
the top & bottom of the galaxy (up & down) tends to have a lot more older, stable systems - perfect for planets with life.
you'll find lots and lots and lots of terraformable worlds, waterworlds, and Earth-likes. If you're lucky, they'll still be untagged.

What's the difference between the sub types of stars, ie what's a G9 VAB and how is it different from a G8 VAB?

I think that one is basically temperature, though google is your friend. The lower the number the hotter it is. I seem to get better results with the lower numbers.

Elite explorer so I've been out in the black at lot, my average is around 1 in 200.

The NASA definition of "Earthlike" is somewhat different from the FD definition, for NASA it's any rocky planet in roughly the right place and of a roughly similar size, for FD it's a verdant world with life and a human breathable atmosphere.

Curious to know what makes a good explorer?

I've found several, but me thinks a bit of luck is involved.

It's luminosity, within the given class. A G9 star is less luminous, and as such, probably cooler than a G8 star. For some lengthy reading, the Wikipedia article on stellar classification is a good one.
For finding Earth-likes, more luminous is not always better. For example, you appear to be more likely to find them around A9 stars than A0, but less likely around K9 stars than K0. Jadefriendly's tips are also pretty solid too.

Of course. All you can do is put yourself in regions where you are more likely to find the things you are looking for. Not every explorer is out Earth-like bagging. And even when you are, there is still lots of luck involved. Every G2 star with nothing at all around it feels unfair, but is just part of the random nature of these things.

I've found 34 out of 8396 systems so far, so that's 1 in 247 systems for me. But I've not been specifically searching out earth likes or stars that would be more probable to have them. I'm just pootling around ;)

On my last trip i combined my previous experience with knowledge gained from other explorers, including one guy who had been collecting statistics on stars and their planets and shared some quite useful info.

I found i could get Earthlikes down to less than 1 in 50, probably close to 1 in 30. Waterworlds around 1 in 10. Ammonia Worlds somewhere between 1 in 10 and 1 in 20.

Basically, hot A, F, G types are your best bet, with F's being much better than A and G for nice planets. Single star systems tend to be more stable for finding an earthlike or two (or some combination with water worlds, or perhaps binary pairs), but with multi-star systems you can hit jackpot sometimes and get quite a few good planets.

If you want to find lots of F type stars, go to the Eagle Nebula. Its already been scanned to death (it was scanned to death even before new year as i understand), so no first discoveries, but you will find lots of nice planets there, because every single star is a F2V or F5V (forget which).
