LHS 1903 e orbits a red dwarf M-type star 116 light-years distant, a super-Earth with 1.7 × Earth radius and 5.8 Earth masses, revealing high density and gas-poor composition. Orbiting every 29.3 days at 0.15 AU, it sits near the habitable zone’s outer edge despite its system’s unusual architecture—rocky outermost after inner gas-rich worlds. This anomaly challenges formation models, suggesting unique accretion in depleted disks. It stands as a fascinating entry in the Galactic Codex, expanding our understanding of diverse rocky planet pathways around cool stars.
