How likely are we to witness an occlusion of Sgr A, if one were to happen? Its diameter is smaller than the Sun-Mercury orbit[1], plus the stars in close orbit have a period of 11 years at the shortest. So they're far away from A* plus they don't transit very often. 1. https://en.wikipedia.org/wiki/Sagittarius_A* https://en.wikipedia.org/wiki/Sagittarius_A*
