That means that two stars are close together, orbiting their common center of mass.
No. A Galaxy contains billions of stars whereas a binary star contains only two stars.
It is estimated that around half of all stars in the Milky Way galaxy exist in binary or multiple star systems. This means that approximately 100 billion stars in our galaxy could be part of such systems. Many of these binaries consist of pairs, while others may involve three or more stars bound by gravity.

A binary star is a system of two stars gravitationally bound together that are constantly orbiting each other.
All functions are relations but all relations are not functions.
You can have a multiple star system; many are known. They are gravitationally stable and have the form of binary pairs of stars in concentric orbits about the most massive pair. In theory a system of 220 is possible, but such a system would have to a galaxy unto itself. If it were inside a galaxy it would be perturbed and pulled apart.
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
A binary relation is a relation, such as "is less than" or "is the daughter of", which makes statements about pairs of objects, being true or false depending on the objects.
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
binary stars, more than 50 percent of the stars in the universe may occur in pairs or multiples.
No, oddly enough, the noun bra (short for brassiere) is not a binary noun*. The noun bra is a count noun (one bra, two bras, a dozen bras). Binary nouns are non-count nouns, for example the binary noun 'shorts' is one pair of shorts or two pairs of shorts, the noun shorts is a plural noun with no singular form.*Binary nouns are words for things that are two parts making up the whole; binary nouns are a shortened form for 'a pair of'.
It is found in the constellation of Canis Minor, and is actually a binary star system. Like all the stars that we can see, it is in the same galaxy as us, which is the Milky Way.
