GJ 1137 c
GJ 1137 c is a super-Earth exoplanet with a minimum mass of ~5 Earth masses, orbiting the K2 dwarf star GJ 1137 (also HD 93083) at 93 light-years. Detected via radial velocity amid the star’s 32-day magnetic rotation cycle, its 9.6-day period suggests a hot, rocky world unlikely to host liquid water. The system includes […]
TOI-2267 d (candidate)
TOI-2267 d is an Earth-sized candidate in the same M5V-M6V red dwarf binary, with a 2.03-day orbit detected in TESS data but awaiting full validation. At 72 light-years, its potential rocky nature fits the system’s theme of small planets in a compact setup. Radius ~0.95 R⊕ if around primary, or ~1.13 R⊕ secondary. Dynamical models […]
TOI-2267 c
Part of the TOI-2267 binary red dwarf system (M5V-M6V), this slightly larger-than-Earth exoplanet transits with a 3.49-day period, indicating a warm, non-habitable environment despite potential rocky composition. Confirmed alongside b via TESS and high-res imaging, it highlights efficient planet formation in tight binaries at 72 light-years. Radius estimates vary by host: ~1.14 R⊕ around the […]
TOI-2267 b
TOI-2267 b is an Earth-radius exoplanet orbiting in a compact binary system of two cool red dwarfs, M5V and M6V, separated by just 8 AU. Detected via TESS transits and confirmed with ground-based follow-up, its 2.28-day orbit suggests a scorching surface temperature, far from habitable despite its rocky size. The system, only 72 light-years away, […]
GJ 887 d
GJ 887 d is a Neptune-like exoplanet with a mass over 6 Earths, orbiting a nearby red dwarf every 50.8 days at 0.212 AU. Positioned near the inner edge of the habitable zone, its equilibrium temperature around 250-300K could support liquid water with a thick atmosphere, though its gaseous nature likely precludes rocky surfaces. Confirmed […]
LHS 1903 e
LHS 1903 e is a super-Earth exoplanet orbiting a red dwarf star in an unusual “inside-out” system where rocky planets bookend gaseous ones. With a mass of about 5.8 Earths and orbiting every 29.3 days at 0.15 AU, it sits near the outer edge of the habitable zone, potentially allowing liquid water if it has […]
TOI-7384 b
TOI-7384 b is a fresh super-Earth addition to the NASA Exoplanet Archive on February 5, 2026, with a mass of 12.4 Earths—implying a radius about 1.9 times Earth’s for a rocky world. Located around 218 light-years away, it was detected by NASA’s TESS mission through transit dips in its host star’s light. The star’s type […]
GJ 3090 c
GJ 3090 c, a super-Earth with a mass of about 10 Earths, was added to the NASA Exoplanet Archive on February 5, 2026. Orbiting the M-dwarf star GJ 3090 roughly 73 light-years away, it likely has a radius around 1.8 times Earth’s, suggesting a dense, rocky core with possible volatile layers or thick atmosphere. As […]
HD 137010 b
HD 137010 b is a candidate rocky exoplanet slightly larger than Earth, orbiting a Sun-like star at about 146 light-years. Its orbital period is around one year, similar to Earth, and it may lie near the outer edge of the star’s habitable zone, where liquid water could exist under a suitable atmosphere. However, the star […]
Barnard b
Barnard b is a sub-Earth-mass exoplanet orbiting Barnard’s Star, the nearest single star to our Sun at just 6 light-years away. Detected using the European Southern Observatory’s Very Large Telescope and instruments like ESPRESSO over five years of observations, it has a mass of about 0.3 Earth masses and completes an orbit every 3.2 days […]
