In February 2026, CHEOPS revealed a four-planet system arranged rocky → gaseous → gaseous → rocky — an 'inside-out' configuration where the outermost world is a small rocky super-Earth, not a gas giant. Standard theory says rocky planets form close to stars where temperatures vaporize gases, while gas giants form in the cold outer reaches. LHS 1903e broke this rule. The likely explanation: it formed late, after the system's primordial gas had already dissipated. A planet born from rock alone.","shortDescription":"A planetary system that formed inside out"}}
