These are potentially habitable exoplanets discovered by different ground or space observatories, some still unconfirmed.

They are divided into a conservative sample

(i.e. those more likely to be rocky and support surface liquid water

) and an optimistic sample (i.e.

those less likely to be rocky or support surface liquid water

)

.

Mass or radius for an iron, rocky, and water composition are given when not available for comparison purposes ( Seager et al., 2007 ). Equilibrium temperatures are calculated assuming a 0.3 bond albedo.

All planets are sorted by an

based on how similar they are to Earth's stellar flux and size (either measured from mass or radius).
