     Canis Major is one of the 88 modern constellations, and was included in the 2nd century astronomer Ptolemy's 48 constellations. Its name is Latin for 'greater dog', and is commonly represented as one of the dogs following Orion the hunter (see also Canis Minor the 'lesser dog'). Canis Major contains Sirius, the brightest star in the night sky, known as the 'dog star', which is part of the asterism known as the Winter Triangle in the Northern Hemisphere, or the Summer Triangle in the Southern. The star is also recognized as Canis Major's nose.

     Canes Venatici is one of the 88 official modern constellations. It is a small northern constellation that was created by Johannes Hevelius in the 17th century. Its name is Latin for "hunting dogs", and the constellation is often depicted in illustrations as representing the dogs of Boötes the Herdsman, a neighboring constellation.
   The stars of Canes Venatici are not bright. In classical times, they were included by Ptolemy within the constellation Ursa Major in his star catalogue. α CVn was Ptolemy's "28th of Ursa Major", and β CVn was his "29th of Ursa Major"

    Cancer is one of the twelve constellations of the zodiac. Its name is Latin for crab and it is commonly represented as such. Its symbol is Cancer glyph.png (Unicode ♋). Cancer is small and its stars are faint. It lies between Gemini to the west and Leo to the east, Lynx to the north and Canis Minor and Hydra to the south.
   Cancer is said to have been the place for the Akkadian Sun of the South, perhaps from its position at the summer solstice in very remote antiquity. But afterwards it was associated with the fourth month Duzu (June–July in the modern western calendar), and was known as the Northern Gate of Sun.

   Camelopardalis is a large but faint constellation in the northern sky. The constellation was introduced in 1612 (or 1613) by Petrus Plancius. In older astronomy books, one will sometimes see an alternative spelling of the name, Camelopardus.
    First attested in English in 1785, the word camelopardalis comes from the Latin and it is the romanisation of the Greek "καμηλοπάρδαλις" meaning "giraffe", from "κάμηλος" (kamēlos), "camel" + "πάρδαλις" (pardalis), "leopard", due to its having a long neck like a camel and spots like a leopard.

     Caelum is a faint constellation in the southern sky, introduced in the 18th century by Nicolas Louis de Lacaille. Its name means "the chisel" in Latin, and it was formerly known as Cæla Sculptoris, "the sculptor's chisel". It is the eighth smallest constellation, with an area just less than that of Corona Australis.
    Caelum is a faint constellation, having no star brighter than fourth magnitude. Its brightest star is the magnitude 4.45 α Caeli. A small telescope splits γ Caeli into a magnitude 4.5 red giant and a magnitude 6.34 white giant. Larger telescopes are needed to see several NGC objects, all galaxies, but none brighter than magnitude 11.5 or larger than 3 arcminutes. Most notable galaxies are NGC 1571, NGC 1679 and IC 2106.

     Boötes (US: /boʊˈoʊtiːz/ UK: /bəʊˈəʊtiːz/, or boh-'oh-tees) is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. The name comes from the Greek Βοώτης, Boōtēs, meaning herdsman or plowman (literally, ox-driver; from boos, related to the Latin bovis, “cow”). The "ö" in the name is a diaeresis, not an umlaut, meaning that each 'o' is to be pronounced separately.

Boötes was one of the 48 constellations described by the 2nd century astronomer Ptolemy and is now one of the 88 modern constellations. It contains the third brightest star in the night sky, Arcturus.

     Auriga is a constellation in the northern sky. Its name is Latin for 'charioteer' and its stars form a shape that has been associated with the pointed helmet of a charioteer. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains among the 88 modern constellations today. Its brightest star is Capella.

Mythology
      In Greek mythology, Auriga is identified as the mythological Greek hero Erichthonius of Athens, the chthonic son of Hephaestus who was raised by the goddess Athena. According to the anonymous writer of the composition Catasterisimi, Erichthonius was generally credited to be the inventor of the quadriga, the four-horse chariot, which he used in the battle against the usurper Amphictyon, the event that made Erichthonius the king of Athens. Erichthonius then dedicated himself to Athena and soon after, Zeus raised the Athenian hero into the night sky in honor of his ingenuity and heroic deeds 
     Capella is associated with the mythological she-goat Amalthea. It forms an asterism with the stars ζ Aurigae and η Aurigae, which are known as the Haedi (the Kids).

     Aries (English pronunciation: /ˈeə.riːz/) is one of the constellations of the zodiac, located between Pisces to the west and Taurus to the east. Its name is Latin for ram, and its symbol is Aries.svg (Unicode ♈), representing a ram's horns. Aries was one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.

History
     In the description of the Babylonian zodiac given in the clay tablets known as the MUL.APIN, the constellation now known as Aries was the final station along the ecliptic. It was known as MULLÚ.ḪUN.GÁ, "The Agrarian Worker". The MUL.APIN is held to have been compiled in the 12th or 11th century BCE, but it reflects a tradition which takes the Pleiades as marking vernal equinox, which was the case with some precision at the beginning of the Middle Bronze Age (early 3rd millennium BCE).
     In later Babylonian tradition, the name of the constellation changes to MULUDU.NITÁ "ram". The motive for the name change is unknown. John H. Rogers suggests that the "Agrarian Worker" became the "Ram" via association with the legendary figure of Dumuzi the Shepherd. Gavin White suggests that the sumerogram  "man" may have come to be understood as Akkadian lu "sheep".
     Aries only rose to its prominent position as the leading sign of the zodiac in the Neo-Babylonian (7th century BCE) revision of the Babylonian zodiac, as Hamal (α Ari) came to be located close to the point of vernal equinox.
     In Hellenistic astrology, the constellation of Aries is associated with the golden ram of Greek mythology that rescued Phrixos, taking him to the land of Colchis. Phrixos sacrificed the ram to the gods and hung its skin in a temple, where it was known as the Golden Fleece.
