Revision as of 10:22, 8 December 2011 by Bender235 (talk | contribs)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)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 | ||
61 Virginis b | 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 | 4,2 | 0,047 | 0 | No. Orbits too close to the star | HD 40307 | 42 | ||
HD 40307 c | 6,8 | 0,081 | 0 | No. Orbits too close to the star | HD 40307 | 42 | ||
HD 40307 d | 9,2 | 0,134 | 0 | No. Orbits too close to the star | HD 40307 | 42 | ||
Note: all masses except of 55 Cancri e, HD 40307 b and Gliese 876 d are minimal masses
