TOI-2267 c shares the compact M-dwarf binary with its sibling, sized 1.1 × Earth and orbiting every 3.5 days at 0.0263 AU. As part of this tight configuration, it navigates complex dynamics while maintaining a rocky profile. The system’s proximity and transiting nature make it a benchmark for binary-hosted planets. It stands eternally in the Galactic Codex, exemplifying how Earth-like worlds can thrive amid the gravitational interplay of close stellar companions.
