A constellation is a group or constellation of stars that seemed connected to form a special configuration. In the three-dimensional space, most of the star we observe do not have a relationship with one another, but it can be seen as a group on the ball the night sky. Humans have a very high ability to recognize patterns and throughout history have grouped stars that appear near the constellation, constellations. Composition of the constellation unofficial, that is widely known by the community but not recognized by astronomers or the International Astronomical Association, also called asterisma. The stars in the constellations or rarely asterisma a related astrophysics; they just happened to appear close together in the sky visible from Earth and are usually very far apart.

The grouping of stars into constellations is quite random, and different cultures will have different constellations too, though some of the most easily recognized are often found, such as Orion or Scorpius.

The International Astronomical Association has divided the sky into 88 official constellations with the boundaries clear, so that each direction is only possessed by only one constellation. In the hemisphere (hemisphere) north, most of the star constellations are based on Greek tradition, passed down through the Middle Ages, and contains the Zodiac symbols.
