Some Stars are found in groups or clusters. These groups of stars are called Constellations. Some of them seem to be forming a shape. A group of Star thus forming a shape is called a constellation.
The biggest Star in the north is the pole Star the north Stars. It appears to remain in the same position in the sky. It is almost directly above the north pole. In India it is called Dhurv Tara.
The Ursa Major, Orion, Canis Major, Scorpio and Cygnus are some other well-known Constellations.
A Constellations is an area of the celestial sphere as defined by the International Astronomical Coalescence (IUA) in the early 20th century. Constellations are utilized for orientation and arranged in a grid-like map of the welkin. They are typically grouped around asterisms, patterns composed by effulgent Stars that appear proximate to each other in the night welkin.
In 1913 the international astronomical Coalescence officially listed 88 modern and archaic constellation (one of the antediluvian constellations was divided into 3 components) and drew a boundary around each. The boundary edges meet dividing the imaginary spare--the celestial spare--circumventing Earth into 88 pieces. astronomers consider any star within a constellation boundary to be a component of the constellation even if it is not a component of the the authentic picture.
48-of the constellation are known as archaic aur pristine, Denoting they were verbalized about by the Greeks and probably by the Babyloans and still earlier peoples. After the 15th century, with the age of the great revelation and economical navigation, the southernmost components of the firmament become known to man and had to be charted.
★ How do Constellations get their name
Constellation designations, like the denominations of Stars emanate from a variety of sources and each has a different story and meaning to it.

One the constellation is Ursa major or the Great Bear, which can be easily recognised in the northern sky. It is called saptarishi in India. It is a group of seven Stars the form of part of Ursa Major. The two Stars at the end of this constellation are called pointers. They always point towards the north.

★ More about Constellations
A Constellations is an area of the celestial sphere as defined by the International Astronomical Coalescence (IUA) in the early 20th century. Constellations are utilized for orientation and arranged in a grid-like map of the welkin. They are typically grouped around asterisms, patterns composed by effulgent Stars that appear proximate to each other in the night welkin.
A constellation is a group of visible star that form a pattern when viewed from Earth. The pattern they compose may take the shape of an animal, mythological creature, a man, a woman or an inanimate object such as a microscope, a compass, or a crown.
The word constellation has its roots in the Tardy Latin terms constellatio, which can be translated as "seat of stars". a more functional definition would be a recognisable pattern of stars who appearance in associated with methical characters, creatures, or certain characteristics. It's withal paramount to note that colloquial utilisation of the word "Constellation" does not generally differentiate between an asterism and the area circumventing one.
★ History of observation
It is believed that since the earliest humans ambulated the Earth, the traditions of looking up at the night firmament and assessing names and characters to them subsisted. However the earliest recorded evidence of some and constellation-designating comes to us from antediluvian Mesopotamia, and in the form of etching on clay tablets that are dated to around ca. 3000 BCE

Old constellations' names customarily emanate from Greek mythology, well the constellation engendered more recently were mostly denominated after scientific instrument and exotic animals. However, there are no rigorous because the story of constellation differ from one constellation to the next.
Many stars have names that we save including Polaris ( additional known as the North Star). Others simply have designations that look akin to a string of number and letters. The most effulgent stars in the firmament have names that date back thousands of year to a time when unclad-ocular perciver visually examining was the state-of-the-art in astronomy so far example, in the constellation Orion, the effulgent Star Betelgeuse ( in his shoulder ) has a denomination that opens up a window into the very distant past, when Arabic disignations were assigned to the very most effulgent stars
