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 conditions exemplify how common cool stars can host Earth-like worlds. It endures as a highlight in the Galactic Codex, enriching our understanding of widespread habitability across the Milky Way.
