Most of the (northern) constellations we use today were invented in ancient times, especially by the ancient Greeks. More recently, a few were added (to fill the entire surface of the sky with constellations), and the limits between constellations were defined exactly.

The "classical" zodiac consists of 12 constellations, most of them represent some animal (hence the name). According to the current definitions of constellations, however, the Sun goes through 13 constellations.The "classical" zodiac consists of 12 constellations, most of them represent some animal (hence the name).

Quite simply, this is the way constellations are defined. Constellations are arbitrary groupings of stars; somebody considered that a certain group of stars looks like a bear, and called it "big bear". This is one of the 88 official constellations recognized by modern Astronomy; you can look for other images in the stars, i.e., groups of stars. Those groups might be part of a constellation, or they may span more than one constellation. The Big Dipper happens to be part of a larger "official" constellation: the Big Bear (Ursa Major).Quite simply, this is the way constellations are defined.

Groundhog Day! We note the "holidays" of the two solstices and the equinoxes when note the end of one season and the beginning of the next, but the mid-season days are often noted as well. Halfway through the northern hemisphere winter is Groundhog Day on February 2. The earlier pagan holiday of Imbolc was on that day, or on the night preceding it. Halfway through the Northern Hemisphere spring is the old pagan holiday of Walpurgis Night, on April 30, or Beltane, celebrated on May 1. Many non-pagans celebrate "May Day" on that date. The middle of the northern hemisphere Summer on August 1 isn't so much observed in modern cultures, but the old celebration of Lammas matches it. The middle of the northern fall is one of our favorite holidays, Halloween - or to use the pagan name, Samhain. The Christian holidays of All Hallow's Eve followed by All Saints Day match this.
Draco is a constellation in the far northern sky. Its name is Latin for dragon. Draco is circumpolar (that is, never setting) for many observers in the northern hemisphere. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.Source: Wikipedia.
The sky has been divided into 88 official constellations used in modern astronomy, covering both hemispheres. These include the 12 traditional signs of the zodiac.Any other grouping of stars (such as the northern hemisphere's Summer Triangle) is more correctly referred to as an asterism.
Yes, each constellation has a French name. The International Astronomical Union recognizes 88 modern constellations. Forty-eight constellations represent those mentioned in classical Greek sources while those in the southern hemisphere serve as sixteenth- to eighteenth century additions to what can be seen in the northern hemisphere.
Greece, whether ancient or modern, is in both the northern hemisphere and the eastern hemisphere (thus, it is in the northeast quadrant).
The constellation Ursa Minor, the little bear, contains the star Polaris which, in modern times appears to remain stationary above the North Pole. This can help people in the Northern hemisphere locate the northward direction.There are other constellations which rise and set at different times of the night in different seasons. This information can be ueful in telling the time.
Faint stars were not included in ancient constellations and regions of the southern sky were not visible to the ancient astronomers of northern latitudes. (source: Michael A. Seed's Foundations of Astronomy)

Since ancient Greece maybe, the ancient Greeks named the 88 constellations. Edit: It was probably the Babylonians who really started naming groups of stars. The modern system of 88 constellations was only finalised in the last century. Obviously the Babylonians, Greeks, etc., couldn't even see the stars that can be seen only from the Southern Hemisphere.
Hercules is a constellation named after Hercules, the Roman mythological hero adapted from the Greek hero Heracles. Hercules was one of the 48 constellations listed by the 2nd century astronomer Ptolem, and it remains one of the 88 modern constellations today. It is the fifth largest of the modern constellations.
Crux is the smallest of the 88 modern constellations

Constellations are of mainly historical importance, as a record of the way in which the human race used to think about the stars. Modern astronomers do not categorize stars according to constellations, since they have more meaningful criteria. Astrologers, of course, continue to attribute vast mystical significance to constellations.
