Currently identified exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky.[3][1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition.[4] Earth is included for both comparison and reference, while Venus and Mars are included for reference only. The data are current to early 2025, but are being updated (on the source cited) as more data arrive.
