These are artistic representations of all the planets around other stars (exoplanets) with any potential to support surface life as we know itMost of them are larger than Earth and we are not certain about their composition and habitability. They are ranked here from closest to farthest from Earth. This selection of objects of interest is subject to change as new interpretations or astronomical observations are made. Earth, Mars, Jupiter, and Neptune are shown for scale on the right.

Table Notes

  1. The database of the Habitable Exoplanets Catalog (HEC) includes both confirmed and unconfirmed exoplanets. 
  2. Estimates based on the NASA Kepler Candidates, but some already confirmed and included in HEC.
  3. Confirmed planets listed by the PHL's Exoplanet Catalog. Check here for comparisons with other exoplanet databases.
  4. Most of NASA Kepler Candidates are still unconfirmed exoplanets.
