List of super-earths
Listed here are the previously known super-earths , i.e. extrasolar terrestrial planets .
In most of these planets, the earth-like structure has not yet been proven beyond doubt (see main article ) . Definitely proven rock planets are shown in bold .
Super-earths
Super-earths discovered so far:
In the future, the number of known super-earths could increase dramatically if many of the Kepler Space Telescope's planet candidates are confirmed. Of the 1235 candidates discovered by early February 2011, 288 are super-earths.

Remarks
- (1)Due to the neglected and often unknown inclination, the known mass is mostly only the lower limit of the possible planetary mass, represented by ">".
- (2)The radius information is an estimate - all other astrometric and physical information is measurement-based approximate values
Footnotes
- 1The latest findings indicate that the mass of the parent star is significantly higher and that it is not a brown but a red dwarf, which results in a newly determined mass of only 1.4 Earth masses for the exoplanet . Should this be confirmed, there would be no system around a brown dwarf as yet.
- 2another exoplanet CoRoT-7d unconfirmed; if confirmed, different values for CoRoT-7 b and c
- 3Exoplanets HD 1461 c and d unconfirmed; given values correspond to the 1-planet scenario
