LHS 1140b
LHS 1140b is a rocky exoplanet roughly 48 light-years from Earth, orbiting the quiet red dwarf lhs-1140 every 24.7 days at ~9 million miles. First discovered in 2017 via the transit method, it has a diameter ~1.7x Earth’s and a mass ~5.6x Earth’s (confirmed via radial-velocity).

A 2026 Science study led by collin-cherubim (university-of-chicago) confirmed LHS 1140b is the first known exoplanet to combine the right size, a habitable-zone orbit, and a confirmed atmosphere — detected via helium bleed-off in transit spectroscopy. Climate models predict CO₂, CO, trace O₂, and abundant water beneath the helium. LHS 1140’s low X-ray output (~10x Earth’s vs. Proxima Centauri’s ~400x) makes the planet notably more favorable to surface life than other nearby habitable-zone candidates like gj-887-d. The study does not claim evidence of actual life.
