Revision as of 10:10, 23 September 2011
This list of nearest terrestrial exoplanets contains known terrestrial exoplanets at a distance of up to 50 light-years from the Solar System, ordered by increasing distance.
There are 10 terrestrial exoplanets, 2 of whose are 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 | Yes. Lie 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 | Yes. 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
