HD 63433 d, an interesting exoplanet and report. At least 3 exoplanets reported in this system.

Planet HD 63433 d

Detailed information about planet HD 63433 d and its parameters.

I note using the exoplanet.eu site, exoplanets with radii 0.38 to 1.2 earth size number 395 (includes TRAPPIST-1 system) and at the nasa archive site, 384 (incudes TRAPPIST-1 system). A large number of exoplanets shown now with sizes like Mercury, Venus, Earth, and Mars. Little or no reporting showing these exoplanets have abundant liquid water and life on them.

FYI, here is another report on an exoplanet close to earth size known but again, very different than our home world.
