Binary stars are physically related stars that orbit each other due to mutual gravitational attraction, while optical doubles are stars that only appear to be close together in the sky but are not physically associated. Binary stars can be confirmed through their gravitational interaction, while optical doubles are simply a line-of-sight effect.
