GJ 887 d orbits in its star's habitable zone every 50.77 days, receiving 81% of Earth's solar energy, with equilibrium temperature around minus 32°C before atmospheric warming. The 2026 confirmation required 277 nightly observations to separate a faint 1.7 m/s stellar wobble from the red dwarf's own magnetic activity and 38.7-day rotation.
