Fei Xin is an extremely hot and volcanically active world. A thick carbon dioxide and ethane atmosphere covers an iron-rich surface with deposits of calcium.
Active volcanic site
Profile: Shield volcano with current effusive eruption
Lava composition: Basalt flow with unknown materials
This volcano has recently erupted. Fei Xin's unusually strong gravity (3.2 G) means the lava flow is localized and may be valuable for study.
