Exoplanet Discoveries and Updates

I assume they're not exactly new. The idea is probably around for quite a long while, maybe at least a decade, but only after Kepler starts revealing the planetary demographics do we learn that many planets are super-Earths and sub-Neptunes. We don't have those in OA, so we don't see many of them in OA as a result. More at here for figuring out what these planets may be like, and here for planetary abundances.
