Smallest Exoplanet with Potential Sulfur-Rich Atmosphere Discovered

Tentative evidence suggests the exoplanet L 98-59 d, a super-Earth 1.5 times the size of Earth located 35 light-years away, possesses a sulfur-rich atmosphere. The potential presence of sulfur dioxide (SO₂) and hydrogen sulfide (H₂S) hints at a molten or volcanic surface. If confirmed by future James Webb Space Telescope observations, this would make L 98-59 d the smallest known exoplanet with an atmosphere.
