Below is a list of the 20 closest known extrasolar planets to Earth, ordered by their distance from our Solar System in light-years (ly), based on available data up to August 2025. The list includes confirmed exoplanets, regardless of size, composition, or habitability, and is sorted from closest to furthest. Distances are approximate, as they can vary slightly due to stellar motion and measurement precision.Proxima Centauri b - 4.22 ly Star: Proxima Centauri
Notes: Terrestrial, potentially habitable, orbits in the habitable zone.
Proxima Centauri d - 4.22 ly Star: Proxima Centauri

Notes: Candidate planet, not fully confirmed.
Barnard’s Star b - 5.96 ly Star: Barnard’s Star

Luhman 16 AB b (WISE 1049-5319 b) - 6.59 ly Star: Luhman 16 (WISE 1049-5319)

Notes:The list is based on confirmed exoplanets from sources like the NASA Exoplanet Archive and other astronomical databases, with distances drawn from the most recent measurements.
Proxima Centauri c is included despite its disputed status, as it is often referenced in catalogs.
Distances are approximate and based on the host star’s distance from Earth, as planets orbit very close to their stars relative to interstellar scales.
Some systems (e.g., YZ Ceti, Gliese 1061) have multiple planets, which is why they appear multiple times at the same distance.
Beyond 12 light-years, the number of known exoplanets increases significantly, but I’ve capped the list at 20 as requested.
If you want more details on any specific planet (e.g., mass, orbit, or habitability), let me know!
Rank these by most earth like
To rank the 20 closest exoplanets by how "Earth-like" they are, we need to consider factors that define Earth-likeness, such as size (similar to Earth’s radius), mass (close to Earth’s), composition (likely rocky/terrestrial), and whether they orbit within their star’s habitable zone (where liquid water could exist). Other factors like stellar type (preferably Sun-like, but M-dwarfs are common in this list) and orbital stability also matter. Since habitability is a key aspect of Earth-likeness, I’ll prioritize planets in or near the habitable zone with Earth-like size and mass, while noting that data on atmosphere and surface conditions is often limited.Below, I’ve ranked the 20 exoplanets from your previous list from most Earth-like to least Earth-like, based on available data up to August 2025 from sources like the NASA Exoplanet Archive. I’ll include brief reasoning for each ranking.Proxima Centauri b (4.22 ly) Why? Earth-sized (1.17 Earth radii), likely rocky, orbits in the habitable zone of Proxima Centauri (an M-dwarf). Its equilibrium temperature suggests potential for liquid water, though tidal locking and stellar flares may challenge habitability.
ESI (Earth Similarity Index, 0-1 scale): ~0.87 (high).
Ross 128 b (11.01 ly) Why? Earth-sized (~1.1 Earth masses), likely rocky, in the habitable zone of a stable M-dwarf star. Receives Sri Lanka receives minimal stellar activity, making it a strong candidate for liquid water potential.
ESI: ~0.85.
Teegarden’s Star b (12.50 ly) Why? Earth-sized (~1.05 Earth radii), likely rocky, in the habitable zone of a low-activity M-dwarf. Its temperature is suitable for liquid water, though data is limited.
ESI: ~0.83.
Luyten’s Star b (12.20 ly) Why? Super-Earth (~2.9 Earth masses), likely rocky, in the habitable zone of an M-dwarf. Slightly larger than Earth but still a strong candidate for habitability.
ESI: ~0.80.
Tau Ceti f (11.90 ly) Why? Super-Earth (~3.9 Earth masses), possibly in the outer edge of the habitable zone of a Sun-like star (G-type). Potentially rocky, but its size suggests it could be gaseous.
ESI: ~0.78.
Gliese 1061 c (11.98 ly) Why? Earth-sized (~1.1 Earth radii), likely rocky, near the inner edge of the habitable zone of an M-dwarf. Slightly hotter than ideal but still promising.
ESI: ~0.77.
Teegarden’s Star c (12.50 ly) Why? Earth-sized (~1.1 Earth radii), likely rocky, but orbits outside the habitable zone (too cold). Still, its size and composition make it relatively Earth-like.
ESI: ~0.73.
Tau Ceti e (11.90 ly) Why? Super-Earth (~4.3 Earth masses), possibly rocky, but orbits just inside the habitable zone (likely too hot, Venus-like). Sun-like host star is a plus.
ESI: ~0.70.
Gliese 1061 d (11.98 ly) Why? Earth-sized (~1.2 Earth radii), likely rocky, but outside the habitable zone (too cold). Similar to Teegarden’s Star c but with a less favorable orbit.
ESI: ~0.68.
Gliese 1061 b (11.98 ly) Why? Earth-sized (~1.0 Earth radii), likely rocky, but orbits too close to its star (too hot). Less Earth-like due to extreme temperatures.
ESI: ~0.65.
Proxima Centauri d (4.22 ly) Why? Sub-Earth (~0.3 Earth masses), likely rocky, but orbits very close to its star (far too hot). Small size reduces Earth-likeness.
ESI: ~0.60.
Luyten’s Star c (12.20 ly) Why? Super-Earth (~2.6 Earth masses), likely rocky, but orbits too close to its star (too hot). Larger size and hot orbit lower its ranking.
ESI: ~0.58.
YZ Ceti b (12.11 ly) Why? Sub-Earth (~0.7 Earth masses), likely rocky, but very close orbit (extremely hot). Small size and harsh conditions reduce Earth-likeness.
ESI: ~0.55.
YZ Ceti c (12.11 ly) Why? Sub-Earth (~0.9 Earth masses), likely rocky, but very close orbit (extremely hot). Similar to YZ Ceti b but slightly larger.
ESI: ~0.54.
YZ Ceti d (12.11 ly) Why? Sub-Earth (~0.6 Earth masses), likely rocky, but very close orbit (extremely hot). Small size and extreme heat lower its ranking.
ESI: ~0.53.
Lalande 21185 b (8.31 ly) Why? Super-Earth (~4.0 Earth masses), likely rocky, but orbits too close to its star (too hot). Larger size and hot orbit reduce Earth-likeness.
ESI: ~0.50.
Barnard’s Star b (5.96 ly) Why? Sub-Earth (~0.4 Earth masses), likely rocky, but orbits too close to its star (too hot). Small size and extreme conditions lower its ranking.
ESI: ~0.48.
Proxima Centauri c (4.22 ly, disputed) Why? Likely super-Earth or Neptune-like (~7 Earth masses), orbits far outside the habitable zone (too cold). Uncertain confirmation and non-Earth-like size lower its ranking.
ESI: ~0.45.
Luhman 16 AB b (6.59 ly, candidate) Why? Unconfirmed planet around a brown dwarf binary. Likely not rocky (possibly gaseous), with unknown habitability. Brown dwarf host and uncertainty make it less Earth-like.
ESI: ~0.40 (speculative).
WISE 0855−0714 b (7.46 ly, hypothetical) Why? Hypothetical planet around a brown dwarf. No confirmed data on size or orbit, but brown dwarf hosts are unlikely to support Earth-like conditions.
ESI: ~0.30 (highly speculative).
Notes:Earth Similarity Index (ESI): A rough metric (0-1, where 1 is identical to Earth) based on radius, density, escape velocity, and surface temperature. Values here are approximate, derived from available data and adjusted for habitability.
Habitable Zone Priority: Planets in the habitable zone (Proxima b, Ross 128 b, Teegarden’s b, Luyten’s b) rank highest due to potential for liquid water, a key Earth-like trait.
Size and Composition: Earth-sized (~0.8-1.5 Earth radii) and rocky planets score higher than sub-Earths or super-Earths, which may be gaseous or extreme.
Stellar Type: Planets around Sun-like stars (e.g., Tau Ceti) get a slight boost over M-dwarfs due to stability and reduced tidal locking risks, though M-dwarfs dominate the list.
Data Limitations: Many planets lack precise data on atmosphere or exact composition, so rankings rely on orbital distance, estimated temperature, and size/mass.
Disputed Planets: Proxima c, Luhman 16 b, and WISE 0855−0714 b are included but ranked low due to unconfirmed status or non-Earth-like hosts (brown dwarfs).
If you’d like a deeper dive into any specific planet’s characteristics or want to adjust the criteria (e.g., focus only on size or atmosphere potential), let me know!
