| Nov 27, 2018 at 23:36 | comment | added | userLTK | I think there's two approaches to making a very rough estimate. The majority of solar systems that Kepler has gotten a good look at are close, based on where most of the planets have been found. en.wikipedia.org/wiki/Exoplanet#/media/… If you wanted to download from here: en.wikipedia.org/wiki/… to a spreadsheet and filter by distance you might get a rough idea of a low estimate. I'd make this an answer if my excel was working and if I had the time work it out. | |

In the scientific literature null results are published, even the comparison of detection biases to what theory would say would be impossible without those. | |

| Nov 22, 2018 at 5:09 | comment | added | Jack R. Woods | It always bothers me that only positive results are published. Sometimes "null results" where we could have detected something can be helpful to the understanding also. | |

| Nov 15, 2018 at 8:07 | comment | added | peterh | @RobJeffries In the current form of the question, I see only a single one. Although it might be considered too broad, I think it is not yet (what the currently accepted most realistic estimation say, I think it is enough clear). | |
| Nov 14, 2018 at 22:32 | comment | added | Harthag | @RobJeffries better? | |
| Nov 14, 2018 at 22:32 | comment | added | Harthag | @AtmosphericPrisonEscape Wow, that was an incredibly helpful search suggestion. A couple of good examples from that search, in the form of an answer, would probably have been (and still might be) the answer I accepted | |

| Nov 14, 2018 at 21:38 | comment | added | AtmosphericPrisonEscape | RobJeffries is right. You might not be aware of this, but this is an extremely wide range of topics. Every detection methods has other biases to discuss those would take a whole lecture. Better google "exoplanet detection bias correction". For example, to derive and correct the transit bias is relatively simple, while already for radial velocity planets it's not. | |
| Nov 14, 2018 at 21:21 | comment | added | Harthag | @RobJeffries Thanks for the heads up. Most of the question marks are in an effort to explain what type of information I'm hoping for, they are not intended to be separate questions in and of themselves. I've re-arranged the post, and added a final summary with an attempt at wording the actual single question. If you have suggestions for additional improvement to the question, please let me know. | |

Re-arranged and added summary for clarity of the actual singular question

| Nov 14, 2018 at 17:05 | comment | added | antlersoft | As you note, all our planet detection methods are biased towards finding large planets in close orbits around small stars. Solar system like ours, with a medium-sized star, smallish planets in ~ 1 year orbits and large planets in distant orbits, are much harder to identify (impossible on the timescales we have been observing so far). We know that solar systems unlike ours are reasonably common, but AFAIK we can't really say that solar systems like ours aren't even more common. | |
