Binary system or more objects such as for trinary stars and trinary asteroids. 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 from one another. They evolve separately and have very little effect on each other. Close binaries are close to each other and are able to transfer mass from one another. They can also be classified based on how we observe them. Visual binaries are two stars separated enough that they can be viewed through a
Binary number combinations of a number of simple basic principles or categories, for which he has been considered a predecessor of computing science and artificial intelligence (see Bonner 2007 <http://lullianarts.net/>, Fidora et al. 2011 <https://www.iiia.csic.es/es/publications/ramon-llull-ars-magna-artificial-intelligence/>). In 1605 Francis Bacon discussed a system whereby letters of the alphabet could be reduced to sequences of binary digits, which could then be encoded as scarcely visible variations in the font in any random text. Importantly for the general theory of binary encoding, he added that this method could be used with any objects at all: "provided those objects be capable of a twofold difference only;
