Answer
Brief Explanations:
A binary - star system consists of two stars. The stars in a binary - star system orbit around their common center of mass. This can cause one or both stars to appear to wobble. Not all stars in a binary system are always visible (e.g., one could be a black hole or a very faint star). And it doesn't have more than two stars or include large groups of stars.

They have stars that might appear to wobble.
