List of Kepler exoplanet candidates in the habitable zone

From Wikipedia, the free encyclopedia
Artist's impression of Kepler, the telescope that detected these exoplanet candidates.

This is a list of unconfirmed exoplanets discovered or detected by the NASA Kepler mission (Kepler Candidates from the NASA Exoplanet Archive) that are potentially habitable.[1][2] Those already confirmed are listed by their Kepler names in the list of potentially habitable exoplanets, and the data may differ when the planets are confirmed. Masses for a pure iron, rocky, and water composition are given for comparison purposes.

The planet candidate KOI-4878.01 could be one of the most Earth-like known planets in terms of size and stellar flux.[3][4][5][6]
