TOI-2267 b
TOI-2267 b transits one component of a compact M-dwarf binary 72 light-years away, with a radius of 1.0 × Earth. Orbiting every 2.3 days at 0.0205 AU, it endures warm conditions far from the habitable zone. In this rare close-binary setup (8 AU separation), it offers clues to planet formation amid gravitational chaos. This compact […]
GJ 887 d
GJ 887 d orbits a bright, tranquil red dwarf M-type star just 11 light-years from Earth, one of the nearest systems to our own. As a super-Earth with a minimum mass exceeding 6 Earth masses, it completes an orbit every 50.8 days at 0.212 AU, residing in the habitable zone where surface temperatures could allow […]
LHS 1903 e
LHS 1903 e orbits a red dwarf M-type star 116 light-years distant, a super-Earth with 1.7 × Earth radius and 5.8 Earth masses, revealing high density and gas-poor composition. Orbiting every 29.3 days at 0.15 AU, it sits near the habitable zone’s outer edge despite its system’s unusual architecture—rocky outermost after inner gas-rich worlds. This […]
Barnard b
Barnard b circles Barnard’s Star, one of the closest at 6 light-years, with an estimated radius around 0.9 × Earth. Its tight 3.2-day orbit lies well inside the habitable zone, resulting in high temperatures. As a sub-Earth in our cosmic backyard, it highlights rocky planet diversity around fast-moving dwarfs. This entry endures in the Galactic […]
K2-18 b
K2-18 b orbits a cool red dwarf M-type star 124 light-years from Earth, measuring 2.4 × Earth in radius with a mass of 8.9 Earth masses. It completes its orbit every 32.9 days at 0.14 AU, comfortably within the habitable zone. Atmospheric studies reveal water vapor, methane, and possible biosignature hints. As a potential ocean […]
Ross 128 b
Ross 128 b circles a serene red dwarf M-type star just 11 light-years distant, with a radius of 1.4 × Earth and mass suggesting rocky composition. It orbits every 9.9 days at 0.049 AU, within the habitable zone where liquid water could persist. The host’s unusually low flare activity enhances atmospheric retention prospects compared to […]
Kepler-62 f
Kepler-62 f circles an orange dwarf K-type star 1200 light-years distant, with a radius of 1.4 × Earth. It completes an orbit every 267 days at 0.72 AU, residing in the habitable zone for liquid water possibilities. As part of a five-planet system, its rocky nature and temperate conditions make it a benchmark for Earth-like […]
TOI-2431 b
TOI-2431 b orbits a nearby K-type dwarf 117 light-years away, an Earth-sized world with 1.5 × Earth radius and 6.2 Earth masses, yielding high density consistent with iron-rich composition. Its extreme 5.4-hour orbit at 0.0063 AU subjects it to intense irradiation and tidal forces, resulting in equilibrium temperatures around 2063 K and likely molten surfaces. […]
GJ 367 b
GJ 367 b transits a nearby red dwarf M-type star 31 light-years away, with a radius of 0.9 × Earth and high density suggesting an iron core. It orbits every 0.32 days at a scorching close distance, far inside the habitable zone. As an ultra-short-period sub-Earth, it reveals extreme planetary stripping processes. This compact beacon […]
55 Cancri e
55 Cancri e orbits a Sun-like K-type star 41 light-years away, with a radius of 1.9 × Earth. Its ultra-short 18-hour orbit creates extreme temperatures, potentially forming molten surfaces. As a classic hot super-Earth, it contrasts temperate worlds and reveals volcanic geology. It remains a dramatic fixture in the Galactic Codex, illustrating the fiery extremes […]
