Exoplanet Habitable Zone Candidates
Estimates of habitable zone migration and duration of exoplanet residency therein
This service provided by planetarybiology.com

Based on data feed from Exoplanets Encyclopaedia
Using methods from Astronomical Circumstances chapter
Note: habitable zone histories are estimated based on star mass.
Variations in spectral quality would result in variations in habitable zone migration
but are not accounted for here.

Sorted by rank(ASC)

Note: Stars get brighter and hotter as they get older.
As a result, the Habitable Zone migrates outward.
