TOI-4616 b transits a nearby mid-M4 red dwarf 92 light-years from Earth, with a radius of 1.2 × Earth. It orbits every 1.55 days at a tight distance, receiving high stellar flux far outside the habitable zone. Its benchmark properties make it valuable for studying rocky planets around cool dwarfs. This steadfast world in the Galactic Codex reveals the extremes of terrestrial formation in close orbits.
