Visibility
From Starsonata Wiki
Visibility is a measure of how well others can see your ship. Higher visibility means you are more clearly seen from a farther distance away. Contrastly, with lower visibility, others will have to get quite close in order to see you. Items with a visibility stat raise your visibility by the indicated amount. Thrusting raises your visibility by the amount listed on the engine, and shooting raises visibility by 10,000 for a few seconds.
