ProfessorBinary 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.

How big is a binary star?
Binary stars can range in size from a few times the mass of the Sun to substantially larger. They orbit each other due to their mutual gravitational attraction, and their distance from one another can vary widely depending on the specific binary system. The size of a binary star is typically measured in terms of their combined mass, distance between them, and orbital period.

What is a binary star system?
A binary star system is a system in which two stars are orbiting around a common center of mass. These stars are bound together by gravity and can orbit each other in various configurations, such as close binaries where the stars are very close together, or wide binaries where they are farther apart. Binary star systems are common in the universe.
