Discussion Looking for Good Data of Systems and Bodies

oldmanklc

O
I've searched quite a bit for a site that can answer a few statistical curiosities I have.

Namely:

  1. What star types are most likely to have _______ planet types
  2. What planet types are most likely to have _______ resources on them
  3. ????

I would've found this info particularly useful on my recent trip to Sag A as I got board and wanted to do things like complete my resource harvesting list.

I did find that eddb.io's api page has a "systems" json file from all systems in the db. It also has a "recent_bodies.json" file of bodies scanned within the past 48 hours. I can cross reference these to files to probably get a ton of stats I'm looking for. But I note EDDB used to have a "bodies.json" file which had 3gb worth of planet data in it. I would much prefer to use something like that over data from last 2 days.

Does anyone have a good idea of some data that cross references a bunch of details about planets with their parent systems?

Another question - does anyone have a copy of the old 3gb+ bodies.jsonl file? While not up to date, it probably has enough data in it to yield some statistically useful results if I ran it through a script.

The answer to 1 is a bit complicated. I did a little digging for you and came across this post that seems to explain what you're after quite well: https://forums.frontier.co.uk/showthread.php/339164-Marx-s-guide-to-finding-Earth-like-worlds

In regards to 2: here's a video by Down to Earth Astronomy on planetary prospecting in general that was posted recently and you might find helpful: https://www.youtube.com/watch?v=0xTRtyUTu3o

As far as determining exactly what kinds of resources may be on a planet, I'm not sure what the secret sauce for that is - presumably it's deterministic via Stellar Forge but there would be a multitude of factors going into this. That said, I think this forum post and the other resources it links to should be helpful to you: https://forums.frontier.co.uk/showthread.php?t=207098

EDDB took down the "bodies.json" dump as compiling a 3GB database dump was proving to be too resource intensive and not feasible at all. Thus the "recent_bodies.json". I will take a look if anybody has a copy of the dump. In the meantime you can try using the API I have developed for EDDB. Check the docs in here

I ended up creating my own site. http://www.eddne.io. It shows the data I was looking for. I've read forum posts and guides including that one - they're mostly correct as verified by my graphs based on real data, but they're also somewhat anecdotal. I'm way too OCD for anecdotal evidence so I had to see something crunching hard data. [yesnod]

For example, I noticed mark's guide mentions "F and A" stars as having a lot of earth likes which is true, but my data also shows "G" star types have slightly more than A and slightly less than F - as far as I can tell, G was not mentioned. Mark mentioned use of data from the EDDN as well so maybe it was missed when he analyzed it? Even more interesting if you find a type K orange giant - your chances go up even more. What % of K stars are orange giants - I probably have the dataset to extrapolate that and will at some point. Is it high enough to make Ks a part of your filter on the galaxy map if you're looking for earthlikes - guessing not but you never know what the data will show.

Yes - I contacted the owner of the site to see if he could zip a copy and sent it to me, just once. I would've loved to get my hands on that data. Instead, I ended up writing a little daemon that snatches scan data out of the eddn and throws it into a mongodb. It's been running since mid december and has at this point, collected more than enough data to justify the numbers I put up the site I created crunching the data @ http://eddne.io.
