Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
The masses of the two stars.
A binary star is a system of two stars gravitationally bound together that are constantly orbiting each other.
Binary stars can appear in a variety of colors depending on the characteristics of the individual stars. The colors can range from blue or white for hotter stars to red for cooler stars. The combination of these colors can create unique visual effects when viewed together in the sky.
There are lots of binary stars. Doing a search on "binary stars" should get you several. It seems that binary (or multiple) stars are about as common as single stars; at least, they are in the same order of magnitude.

Binary stars can be any color that stars can be. There's no need for the two stars in a binary to be the same color.
Binary stars
By definition, a binary star system has two stars in it.
Binary what? Binary numbers? Binary stars? Binary fission?
the orbits of binary stars
Binary stars are very useful for determining the mass of the stars and thus any objects orbiting around them.
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
Research over the last two centuries suggests that half or more of visible stars are part of multiple star systems.
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel
Yes, all binary stars are part of star systems. Binary stars are pairs of stars that orbit around a common center of mass due to their gravitational attraction to each other. While they may be the only two stars in their system, they are still considered part of a larger system.
Yes. Zeta Tauri, Kappa Tauri, and Lambda Tauri are eclipsing binary stars.
