What's the closest distance between two stars that are not gravitationly bound?
Is it common for two stars to be close to each other without being gravitationally bound?
Yes, it is common for stars to be close to each other without being gravitationally bound. In fact, most stars in our galaxy are in multiple star systems, where two or more stars orbit each other. Only a small percentage of stars exist alone, and some stars are close enough to each other to influence each other's motion without being gravitationally bound.
