3M Jupiter is awfully big as compared to Earth. This tells me there are a lot of Earth size ones out there.
There are a number of earth size, I used <= 1.1 earth radii for stat purposes.
325 found at the exoplanet.eu site, mean mass 15.75 earths, most are fairly large masses compared to Earth. 281 I found at the NASA archive site. Mean mass about 9.1 earth masses. The exoplanet.eu site shows 5238 exoplanets orbiting with period 370 days or less so a large population, most have large masses too, e.g. mean about 4.31Jupiter masses. JWST directly imaged this 3 Mjup exoplanet in the space.com report.
So far, I have not seen any of the more than 7300 exoplanets confirmed (exoplanet.eu site), have life or ET phoning home on them
