A binary system is a system of two astronomical bodies which are close enough that their gravitational attraction causes them to orbit each other around a barycenter (also see animated examples). More restrictive definitions require that this common center of mass is not located within the interior of either object, in … See more In a binary system, the brighter object is referred to as primary, and the other the secondary. They are also classified based on orbit. Wide binaries are objects with orbits that keep them apart … See more • NASA Astrobiology Institute Shows How Wide Binary Stars Form - NASA See more • Astronomy: A Visual Guide by Mark A.
