Question: Ursa Minor is one of the constellations based upon what?

full_context: Document 1: Beta Ursae Minoris: Beta Ursae Minoris (β Ursae Minoris, abbreviated Beta UMi, β UMi), also named Kochab, is the brightest star in the bowl of the Little Dipper asterism (which is part of the constellation of Ursa Minor), and only slightly fainter than Polaris, the northern pole star and brightest star in Ursa Minor. Kochab is 16 degrees from Polaris and has an apparent visual magnitude of 2.08. The distance to this star from the Sun can be deduced from the parallax measurements made during the Hipparcos mission, yielding a value of 130.9 ly .
Document 2: Ursa Minor Dwarf: The Ursa Minor Dwarf is a dwarf spheroidal galaxy, discovered by A.G. Wilson of the Lowell Observatory, in the United States, during the Palomar Sky Survey in 1955. It appears in the Ursa Minor constellation, and is a satellite galaxy of the Milky Way. The galaxy consists mainly of older stars and seems to house little to no ongoing star formation. Its centre is around 225,000 light years distant from Earth.
Document 3: Ursa Minor (cave): Ursa Minor Cave is part of Sequoia National Park, a naturally formed system of caves in California's Sierra Nevada. The cave was discovered in August 2006 by four cave explorers from the Cave Research Foundation who found a softball-sized hole on a cliff face in the mountains. After widening the hole to allow for human entry, the explorers discovered one of the most spectacular caves in the western United States. The cave has since been named "Ursa Minor," because of the large bear skeleton found in the cave.
Document 4: Chinese zodiac: The Chinese zodiac is a classification scheme that assigns an animal and its reputed attributes to each year in a repeating 12-year cycle. The 12-year cycle is an approximation to the 11.86-year orbital period of Jupiter, the largest planet of the solar system. It and its variations remain popular in several East Asian countries including China, Korea, Japan, and Mongolia, as well as in other Asian countries like Vietnam, Burma, Nepal, Bhutan, Sri Lanka, Cambodia, Laos and Thailand, along with the Buddhist calendar. According to the Chinese zodiac, 2017 is the year of the Rooster.
Document 5: Ursa Minor: Ursa Minor (Latin: "Lesser Bear", contrasting with Ursa Major), also known as the Little Bear, is a constellation in the Northern Sky. Like the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the North American name, Little Dipper: seven stars with four in its bowl like its partner the Big Dipper. It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Ursa Minor has traditionally been important for navigation, particularly by mariners, because of Polaris being the North Star.
Document 6: Western astrology: Western astrology is the system of astrology most popular in Western countries. Western astrology is historically based on Ptolemy's "Tetrabiblos" (2nd century CE), which in turn was a continuation of Hellenistic and ultimately Babylonian traditions.
Document 7: Sun sign astrology: Sun sign astrology is the form of astrology most commonly found in many newspaper and magazine columns. It is a simplified system of astrology which considers only the position of the Sun at birth, which is said to be placed within one of the twelve zodiac signs. This sign is then called the "sun sign" or "star sign" of the person born in that twelfth-part of the year.
Document 8: Centaurus: Centaurus is a bright constellation in the southern sky. One of the largest constellations, Centaurus was included among the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. In Greek mythology, Centaurus represents a centaur; a creature that is half human, half horse (another constellation named after a centaur is one from the zodiac: Sagittarius). Notable stars include Alpha Centauri, the nearest star system to the Solar System, its neighbour in the sky Beta Centauri, and V766 Centauri, one of the largest stars yet discovered. The constellation also contains Omega Centauri, the brightest globular cluster as visible from Earth and one of the largest known.
Document 9: Pisces (constellation): Pisces is a constellation of the zodiac. Its name is the Latin plural for fish. It lies between Aquarius to the west and Aries to the east. The ecliptic and the celestial equator intersect within this constellation and in Virgo. Its symbol is (Unicode ♓).
Document 10: Canes Venatici: 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. Cor Caroli is the constellation's brightest star, with an apparent magnitude of 2.9. La Superba is one of the reddest stars in the sky and one of the brightest carbon stars. The Whirlpool Galaxy is a spiral galaxy tilted face-on to observers on Earth, and was the first galaxy whose spiral nature was discerned.
Document 11: 88 modern constellations: In modern astronomy, the sky (celestial sphere) is divided into 88 regions called constellations, generally based on the asterisms (which are also called "constellations") of Greek and Roman mythology. Those along the ecliptic are the constellations of the zodiac.
Document 12: Northern Pole: Northern Pole (北极 in Simplified Chinese, "běi jí" in Pinyin) is a traditional Chinese asterism found in the Purple Forbidden enclosure (紫微垣 in Simplified Chinese, "zǐ wēi yuán" in Pinyin). It consists of five stars found in the modern constellations of Ursa Minor and Camelopardalis and represents the five stars of the North Pole. During the Qing dynasty, a total of four stars from the constellation Ursa Minor was added to the asterism.
Document 13: Big Dipper: The Big Dipper (US) or the Plough (UK) is an asterism consisting of seven bright stars of the constellation Ursa Major; six of them are of second magnitude and one, Megrez (δ), of third magnitude. Four define a "bowl" or "body" and three define a "handle" or "head". It is recognized as a distinct grouping in many cultures.
Document 14: Ursa Major: Ursa Major ( ; also known as the Great Bear) is a constellation in the northern sky, whose associated mythology likely dates back into prehistory. Its Latin name means "greater (or larger) she-bear", standing as a reference to and in direct contrast with nearby Ursa Minor, the lesser bear. In antiquity, it was one of the original 48 constellations listed by Ptolemy (2nd century AD), and is now the third largest constellation of the 88 modern constellations.
Document 15: Eta Ursae Minoris: Eta Ursae Minoris, Latinized from η Ursae Minoris, is a yellow-white hued star in the northern circumpolar constellation of Ursa Minor. It has been called Anwar al Farkadain, from the Arabic نور الفرقدين "’anwar al-farqadayn", meaning "the brighter of the two calves". It is then paired with ζ Ursae Minoris as Ahfa al Farkadain, "the dimmer of the two calves". The names may originally refer to a pair of Ibexes, and are more properly applied to β UMi and γ UMi respectively, the brighter two stars in the rectangle of Ursa Minor.
