List of smallest exoplanets

Below is a list of the smallest exoplanets so far discovered, in terms of physical size, ordered by radius.

List
The sizes are listed in units of Earth radii. All planets listed are smaller than Earth and Venus, up to 0.7 Earth radii. The NASA Exoplanet Archive is used as the main data source.

Excluded objects
Kepler-37e is listed with a radius of $$ in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, and assuming its existence, a 2023 study found a mass of $0.31$, inconsistent with such a small radius.

KOI-6705.01, listed as a potential very small planet in the KOI dataset, was shown to be a false positive in 2016.

Kepler and TESS candidates
Below shows a list of Kepler and TESS candidates below that have yet to be confirmed.
