In a visual binary system, the two stars are far enough apart that astronomers can resolve each star as an individual object using telescopes or other instruments. This is different from eclipsing binaries or spectroscopic binaries, where the stars are too close together to be separated visually. Binaries where the two stars have the same mass or luminosity may also be difficult to resolve, as their brightness and movement patterns may be too similar to distinguish them as separate objects.
