Inspired by what CMDR's marx and Orvidius did I was interested in what else we know about certain planets of interest in the galaxy.
Well, actually I discovered many more Ammonia worlds in the Outer Arm Vacuus than Earth-like worlds and wondered why that might be and I tried to analyze the EDSM database and I had some communication with the above mentioned commanders and what they did kind of inspired me, but probably less directly than the above statement might make you think … it just felt important to mention them before I actually start.
So what is this thread actually about.
I've tried to get some statistics how many planets of a certain type where discovered. This turned into something bigger.
When I say discovered I actually mean reported to EDSM. Because this is basically the only source for celestial body data we have.
I then wrote some programs to search the EDSM data for ALL planets of interest, that is planets of a certain type (e.g., Ammonia worlds).
In the 2nd post I will discuss some details and shortcomings of the analysis.
To keep it shorter (and to confuse everybody) I will shorten "planets of interest" to POI.
All this to get an estimate how likely it is, that I will jump into such a system.
Thus I'm not always interested in the absolute number of POI's with a certain chracteristic, but more in the number of systems that contain such POI's
When I was at that, I realized that I wanted to do more.
So I also searched for:
In the 2nd post below I describe how I looked for confirmed moons and how I tried to figure out if a POI was in a binary system with another POI
I've used the EDSM "bodies.json" file from 2019-03-11. It had ca. 65,598,100 entries.
The "systemsWithCoordinates.json"-file was from 2019-03-15 and I've got the number of discovered systems out of there; it was ca. 32,988,800.
I personally am mostly interested in Ammonia worlds. However, earth-like worlds and water worlds are also kind of interesting. The programs can handle every known system … in case anybody is interested in rocky ice worlds … uh oh … I've got an idea.
And now what you came for (thanks to the 10,000 word limit per post I have to refer you, dear reader to post 8 and 9 for explanations).
See the 2nd post for a breakdown of the results before and after the installation of the FSS into our ships at the 3304-12-11 and a brief discussion of the results.

When I was at that, I realized that I wanted to do more.
So I also searched for:
- systems that contain more than one POI
- ringed POI's
- confirmed (!) moons
- POI's that have a moon of the same type
- systems that contain binary systems of two POI's
- systems that contain a ringed POI and at least one other POI
- systems with a ringed POI in a binary system with another POI
- systems with a ringed POI and a POI moon in the same system
- ringed POI's which are a moon.
