Temperature[ | ]
Temperature is a measure of how cold or hot something is. In Osiris, this typically refers to the ambient temperature of the environment.
The Impact[ | ]
Outside temperatures are primarily a threat to an astronaut's health. As long as the space suit remains sealed and intact, the temperature outside is typically just a nuisance... But if it's breached in any way, exposure is imminent and the astronaut starts freezing or starts being cooked. The ultimate difference is trivial.
Of course, the space suit only works in the range of temperatures it's intended for. In case its protection is compromised or exposure to extreme temperatures, it's recommended (or rather, absolutely necessary to survive) to find shelter in a cool or warm location. A habitat with a functioning Climate_Controller is perfect.
