Revision as of 14:26, 12 December 2011

This list of nearest terrestrial exoplanets contains known terrestrial ("rocky") exoplanets at a distance of up to 50 light-years from the Solar System, ordered by increasing distance. They are 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 ten terrestrial exoplanets in this list, two of whom probably lie inside the habitable zone.

Name Image (artist concept) Mass (M⊕) Semi-major axis (AU) Eccentricity habitable? Main source Star Distance from Sol (ly)
Gliese 876 d
6,8 0,021 0,21 No. Surface temperature estimate: 157-377°C Gliese 876 15
Gliese 581 e
≥1,7 0,029 0 No. It is unlikely to possess an atmosphere due to its high temperature Gliese 581 20
Gliese 581 c
≥5,6 0,072 0 Probably no. Likely to lie outside the habitable zone Gliese 581 20
Gliese 581 d
≥5,6 0,218 0 Possibly. Lies within the habitable zone Gliese 581 20

≥5,1 0,050 0,12 No. Orbits too close to the star 61 Virginis 28
HD 85512 b
≥3,6 0.26 0.11 Possibly. Considered to be the best candidate for habitability (as of August 25, 2011) HD 85512 36
55 Cancri e
8,6 0,016 0,17 No. Orbits too close to the star 55 Cancri 40
HD 40307 b
