K2-111 c, a warm sub-Neptune with 11.08 Earth masses, orbits an ancient metal-poor G-star every 15.6785 days at ~0.087 AU in near 3:1 resonance with inner planet b. It features pale blue-cyan haze and a possible thick gaseous envelope—a turbulent world enduring in a 10-billion-year-old system. #exoplanets | Astronomy Wonders
