LHS 1140 b

LHS 1140 b circles a nearby red dwarf M-type star 49 light-years from Earth, with a radius of 1.7 × Earth and mass suggesting high density and possible volatiles. It orbits every 24.7 days at 0.095 AU within the habitable zone. Recent studies point to a possible ocean world composition. As one of the best-characterized […]

TOI-700 d

TOI-700 d is an Earth-sized rocky exoplanet revolving around a stable red dwarf M-type star 101 light-years distant. With a radius of 1.1 × Earth, it orbits every 37.4 days at 0.16 AU in the conservative habitable zone. Low stellar flare activity enhances habitability prospects compared with many M-dwarf systems. Its terrestrial composition and temperate […]

Proxima Centauri b

Proxima Centauri b orbits the nearest star to our Sun, a red dwarf M-type just 4 light-years away. With a radius of 1.0 × Earth, it circles every 11.2 days at 0.05 AU, squarely in the habitable zone where liquid water could exist given a suitable atmosphere. Tidal locking likely creates perpetual day and night […]

Kepler-452 b

Kepler-452 b revolves around a Sun-like G-type star 1800 light-years from Earth, with a radius of 1.6 × Earth. Orbiting every 385 days at 1.05 AU, it lies in the habitable zone of a star remarkably similar to our own. Its host’s age and stability suggest long-term potential for liquid water and life-friendly conditions. As […]

Kepler-186 f

Kepler-186 f orbits a red dwarf M-type star 500 light-years away, boasting a radius of 1.2 × Earth. It completes an orbit every 130 days at 0.43 AU, positioning it in the habitable zone’s outer reaches for potential surface liquid water. As the pioneering Earth-sized world confirmed in such a zone, it provides key insights […]

Kepler-22 b

Kepler-22 b orbits a Sun-like G-type star 600 light-years distant, with a radius of 2.4 × Earth suggesting possible ocean coverage. It circles every 290 days at 0.85 AU, comfortably within the habitable zone. As an early Kepler discovery in such a zone, it bridges smaller rocky worlds and larger gaseous ones, offering clues to […]
