Best M Dwarf

Kepler-1649c is an exoplanet roughly Earth-sized orbiting a red dwarf star named Kepler-1649. Its location within its star’s habitable zone—the region where liquid water could exist on the surface—makes it notable. Scientists study this super-Earth to assess the potential for habitability around M-d...

K2-18b is a sub-Neptune exoplanet orbiting the M dwarf star K2-18. Located within its star’s habitable zone, it has garnered significant attention due to potential liquid water on its surface. Scientists are studying this planet to understand atmospheric compositions and assess conditions suitable f...

TRAPPIST-1c is an Earth-sized exoplanet orbiting the ultracool dwarf star TRAPPIST-1. Located within the TRAPPIST system, it’s notable for its potential habitability due to its size and proximity to its star. The planet transits its star regularly making it a target for atmospheric study. Scientists...

TRAPPIST-1b is an Earth-sized exoplanet orbiting the ultra compact M-dwarf star TRAPPIST-1. Located 39 light-years from Earth, it’s notable as the closest planet to our solar system and one of seven similar-sized planets in a tightly packed arrangement. Scientists study this transiting planet to und...

Discovered in 2017, LHS 1140 b is a super-Earth exoplanet notable for orbiting within the habitable zone of a red dwarf star, making it a prime target for atmospheric characterization.

TOI-700 d is an Earth-sized exoplanet discovered by NASA's TESS satellite in 2020, notable for being one of the few potentially habitable worlds located in its star's habitable zone.

GJ 1214 b is a mini-Neptune discovered in 2009 orbiting a red dwarf 42 light-years away; it was among the first small exoplanets subjected to detailed atmospheric spectroscopic characterization.

Gliese 581 c is a super-Earth announced in 2007 as an early habitable-zone candidate; later analysis concluded it is likely too hot for liquid water due to a Venus-like greenhouse effect.

Teegarden's Star b is a potentially Earth-like planet in the habitable zone of Teegarden's Star (~12.5 ly), discovered in 2019 by Mathias Zechmeister's team.

Ross 128 b is a temperate, near-Earth-mass planet orbiting red dwarf Ross 128 (~11 ly), discovered in 2017 by Xavier Bonfils et al. using the HARPS spectrograph.

VHS 1256 b is a widely separated planetary-mass object notable for having water, methane, and carbon monoxide detected in its atmosphere by the James Webb Space Telescope in 2022.

GJ 667Cc is a super-Earth orbiting within the habitable zone of the M-dwarf component of the triple-star system GJ 667, ~22 light-years from Earth, confirmed in 2012.

Super-Earth confirmed in 2014 orbiting within the habitable zone of Kepler-296, a red dwarf binary system ~1,200 light-years away, making it one of few potentially habitable planets known around a binary star.

Gliese 876 b is a Jupiter-mass planet orbiting the nearby M-dwarf Gliese 876 ~15 light-years away, discovered in 1998, and among the first exoplanets confirmed around a red dwarf star.
