A "binary star" is the word used for two stars that orbit each other around their common center of mass. For example, Alpha Centauri A and Alpha Centauri B are a "binary star" that is the 2nd closest stars to our Sun. (The red dwarf Proxima Centauri is a little closer, but is so dim that it is invisible to the naked eye.)
Two stars that appear to be very close to each other in the sky but are at different distances are a "double star". They aren't associated with each other; they are merely in the same direction.
It is not "a" star it is two stars. They may be "optical" binaries which means that from our line of sight form Earth they APPEAR close together (but are not really) OR They may be a binary star "system", in which case the two stars are gravitationally orbiting one another. The pair may be very close or quite widely separated.
A pair of stars orbiting around each other are called binary stars.

A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two, three, four, or even more stars are called multiple star systems. These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as double (or more) by other means.
