List of nearest terrestrial exoplanet candidates

This list of nearest terrestrial exoplanets candidates contains possible terrestrial ("rocky") exoplanets at a distance of up to 50 light-years from the Solar System, ordered by increasing distance.

They may be composed primarily of silicate rocks and/or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun.

There are no scientific consensus about terrestrial composition of the most of the planets in the list. Sources in the first column confirm the possibility of terrestrial composition.
