List of Exoplanets with the Highest Potential for Extraterrestrial Life
| S. No. | Planet / System | Approximate Distance | Habitability Potential / Characteristics / Status |
| 1 | TRAPPIST-1 e | About 40 light-years | Earth-sized rocky planet in the habitable zone; a leading target for investigating potentially life-supporting conditions. |
| 2 | LHS 1140 b | About 48 light-years | Super-Earth that may have a water-rich environment; atmospheric composition and actual habitability remain uncertain. |
| 3 | TRAPPIST-1 f | About 40 light-years | Potentially habitable-zone planet; liquid water may be possible under suitable atmospheric and climate conditions. |
| 4 | TRAPPIST-1 g | About 40 light-years | Planet in the outer habitable zone; surface conditions and atmospheric protection are unknown. |
| 5 | TOI-715 b | About 137 light-years | Super-Earth in the habitable zone of a red dwarf; a candidate for further habitability studies. |
| 6 | Proxima Centauri b | About 4.2 light-years | Closest known potentially habitable exoplanet; stellar flares and possible atmospheric loss complicate its habitability. |
| 7 | Kepler-442 b | About 1,200 light-years | Super-Earth receiving potentially suitable stellar energy; atmosphere and surface water are unknown. |
| 8 | TOI-700 d | About 100 light-years | Approximately Earth-sized planet in the habitable zone; potentially suitable for liquid water under appropriate conditions. |
| 9 | GJ 1002 b | About 16 light-years | Nearby, approximately Earth-mass planet receiving potentially temperate stellar radiation; surface habitability is unconfirmed. |
| 10 | Wolf 1069 b | About 31 light-years | Approximately Earth-mass planet in its star's habitable zone; atmosphere and surface conditions are unknown. |
| 11 | Kepler-186 f | About 580 light-years | Earth-sized planet in the habitable zone; whether it retains an atmosphere or surface liquid water is unknown. |
| 12 | Ross 128 b | About 11 light-years | Nearby planet orbiting a relatively quiet red dwarf; actual surface conditions remain uncertain. |
| 13 | GJ 1061 d | About 12 light-years | Potentially rocky planet in the habitable-zone region; no confirmed evidence of life or surface water. |
| 14 | Kepler-1649 c | About 300 light-years | Earth-sized planet receiving stellar energy comparable to Earth's; atmosphere and climate are not established. |
| 15 | TOI-700 e | About 100 light-years | Near-Earth-sized planet in the optimistic habitable zone; actual surface habitability remains unconfirmed. |
| 16 | Kepler-62 f | About 1,200 light-years | Super-Earth in the habitable zone; potentially suitable for liquid water under some atmospheric scenarios. |
| 17 | LP 890-9 c | About 100 light-years | Super-Earth near the outer habitable-zone region; its atmosphere and climate are uncertain. |
| 18 | GJ 1002 c | About 16 light-years | Nearby planet in the potentially habitable region of a red dwarf; climate and atmosphere are unknown. |
| 19 | Kepler-1652 b | About 800 light-years | Planet in the habitable zone; its rocky composition and ability to retain liquid water have not been established. |
| 20 | Kepler-22 b | About 600 light-years | Planet orbiting within the habitable zone of a Sun-like star; a rocky surface and Earth-like conditions are not established. |
| 21 | Teegarden's Star c | About 12.5 light-years | Nearby planet receiving relatively low stellar energy; potentially habitable if atmospheric conditions are suitable. |
| 22 | Kepler-1544 b | About 1,100 light-years | Super-Earth-sized candidate in the habitable zone; atmosphere, surface water and climate remain unknown. |
| 23 | TRAPPIST-1 d | About 40 light-years | Small planet near the inner edge of the habitable-zone region; surface habitability depends strongly on atmospheric conditions. |
| 24 | Kepler-452 b | About 1,400 light-years | Planet orbiting a Sun-like star near the habitable zone; its rocky nature and surface conditions are uncertain. |
| 25 | TRAPPIST-1 h | About 40 light-years | Outer, colder planet in the TRAPPIST-1 system; less promising for surface liquid water under typical assumptions. |
Notes:
- This is an indicative list of promising targets for searching for life, not a scientifically proven ranking of the probability that life exists.
- No extraterrestrial life has been confirmed on any of these planets.
- No reliable, scientifically established percentages exist for the probability of life on individual exoplanets.
- The habitable zone indicates where liquid water could potentially exist under suitable atmospheric conditions; it does not establish that water or life is actually present.
- Atmosphere, water availability, temperature, stellar radiation and long-term climate stability all affect habitability.
- Distances are approximate.
