Teegarden’s Star c shares the same quiet red dwarf M-type host as its sibling, only 12 light-years from Earth. Measuring 1.0 × Earth in radius, it orbits every 11.4 days at 0.044 AU, residing in the outer habitable zone. The system’s proximity and the star’s stability make it ideal for future atmospheric probes. This Earth-analog endures in the Galactic Codex as a testament to how diminutive stars can cradle temperate, rocky worlds, expanding our vision of life-friendly environments scattered throughout the Milky Way.
