These are artistic representations of all the planets around other stars (exoplanets) with any potential to support surface life as we know it. Most 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.
