TOI-7166 b orbits a nearby low-mass red dwarf M-type star about 115 light-years away, with a radius of 2.0 × Earth and mass around 4.7 Earths. It completes an orbit every 12.9 days at 0.062 AU, positioning it close to the inner habitable zone edge with an equilibrium temperature near 249 K. As a mini-Neptune in a temperate regime, it offers prime prospects for atmospheric characterization. This accessible world stands in the Galactic Codex, exemplifying how small cool stars can host intriguing sub-Neptune candidates with potential for exotic chemistry and habitability studies.
