- Atmosphere: The atmosphere is 95% carbon dioxide and roughly 100 times thinner than Earth’s. Without a pressurized suit, an "Earthling" would survive only 1-2 minutes.
- Gravity: At 38% of Earth's gravity, long-term physiological effects include muscle atrophy, bone density loss, and vision changes due to fluid shift.
