Petrus Plancius
Who decided the constellations? Many of the 88 IAU-recognized constellations in this region first appeared on celestial globes developed in the late 16th century byPetrus Plancius,based mainly on observations of the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman. What is the history of constellations?

Who invented the constellations and why?

Who Invented The Constellations And Why? With 48, the basis for the modern constellation system here lies. Moreover, Ptolemy produced a catalog of 1022 stars with a brightness estimation as well. This kind of historical work is generally credited with establishing the constellation originates from the Greeks.

Who first used the constellations of the zodiac?

The zodiac was in use by the Roman era, based on concepts inherited by Hellenistic astronomy from Babylonian astronomy of the Chaldean period (mid-1st millennium BC), which, in turn, derived from an earlier system of lists of stars along the ecliptic. The construction of the zodiac is described in Ptolemy ‘s comprehensive 2nd century AD work, the Almagest.

What constellations were first recorded?

As far as we know, they were the first to record their names. Orion, Scorpios, Cygnus, Cassiopeia or the Great Bear are just some of the constellations designated by the Greeks, and which we still know under the same name today. These Greek constellations are perfectly distinguishable in contemporary star maps and charts.

What did the classical constellations represent?

It is widely acknowledged that the classical constellations represented Greek deities and heroes, and were an essential part of the mythology and lore of ancient Greece. What else can the classic works left by the Greeks tell us?

Where did the Greek constellations originate?

Historians have reached the conclusion that the Greek constellations originated in the Mesopotamian civilizations of the ancient Babylonians and Sumerians because of the constellation-free zone found in Greek celestial charts.

Why did the Greeks use the appearance of stars?

One explanation of the origin of the Greek constellations is that it was much easier to read the stars if they were grouped into recognizable shapes and figures.

How many different shapes are there in the night sky?

In this long list of constellations, different figures and shapes are represented in the night sky: 14 men and women, 9 birds, two insects, 19 land animals, 10 water creatures, two centaurs, one head of hair, a serpent, a dragon, a flying horse, a river and 29 inanimate objects. These add up to more than 88 because some constellations include many creatures.

How many constellations are there in Greece?

The Greek constellations today. Astronomers officially recognize 88 constellations covering the entire sky in the northern and southern hemispheres. Among these 88 patterns listed in modern times, 48 constellations originated in ancient Greece.

What is the oldest science?

The constellations are much more than patterns of stars in the sky. They’ve served many purposes in our history as a species. In fact, astronomy is pretty much the oldest science known to mankind. From time immemorial, human civilizations would look up at the sky and wonder what makes it tick.

How many constellations are there?

Astronomers officially recognize 88 constellations covering the entire sky in the northern and southern hemispheres. Currently, 14 men and women, 9 birds, two insects, 19 land animals, 10 water creatures, two centaurs, one head of hair, a serpent, a dragon, a flying horse, a river and 29 inanimate objects are represented in the night sky (the total comes to more than 88 because some constellations include more than one creature.) It is important to realize that the great majority of star patterns bear little, if any, resemblance to the figures they are supposed to represent and whose name they bear. The ancient constellation-makers probably meant for them to be symbolic, not literal, representations of their favorite animals or fabled heroes, a kind of celestial "Hall of Fame."

Who invented them?

The oldest description of the constellations as we know them comes from a poem, called Phaenomena , written about 270 B.C. by the Greek poet Aratus. However, it is clear from the poem that the constellations mentioned originated long before Aratus’ time. No one is sure exactly where, when, or by whom they were invented. And yet a little detective work reveals a plausible origin.

Are there obsolete constellations?

Few of these survived longer than the astronomers who named them, although they sometimes can be seen in antique star charts. For example, in 1678, Edmond Halley (of Halley’s Comet fame) invented a constellation called Robur Carolinum, or Charles’ Oak, in honor of King Charles II of England. This constellation did not last long, especially after its rejection by the French astronomer Lacaille in his maps of the southern sky. In 1754, the English naturalist and noted satirist John Hall invented thirteen constellations based on rather unappealing animals such as a toad, a leech, a spider, an earthworm, and a slug. Fortunately, even though they may have been intended as a joke, they never caught on.

Where do individual star names come from?

The ancient Greek tradition was to name stars by their position within a constellation. For example, Ptolemy refers to one star by the description "the reddish one on the southern eye," a star we now know as Aldebaran in the constellation of Taurus the Bull. But these descriptions could get quite involved. Ptolemy refers to another star in the obsolete constellation of Argo the Boat as "the northernmost of two stars close together over the little shield in the poop," a bit cumbersome if you are trying to learn the names of many stars.

Are all the stars in a constellation the same distance away from us?

No. With few exceptions, the stars in a constellation have no connection with one another. They are actually at very different distances from the sun (see Activity Corner) Chance alignments of stars have created the patterns we see in the sky.

Are the constellations permanent?

Ancient astronomers often spoke of the " fixed stars," which maintained permanent positions in the sky. And, indeed, the stars do seem almost fixed in place; the patterns they form look much the same today as they did when the constellations were first named nearly 3000 years ago. But the stars are all moving relative to the Sun, most with speeds of many kilometers per second. Because they are so very far away, it will take thousands of lifetimes to see significant changes in the star patterns. But, over time, they will change. Because of the motions of the stars within it, for example, the handle of the Big Dipper will, in about 50,000 years, appear significantly more bent than it is today (see figure at left). We will, no doubt, keep the same names for the constellations, even if the stars change their positions. Constellations are, after all, products of human imagination, not nature.

What are some examples of stars that Ptolemy named?

For centuries, bedouin Arabs had given names to bright stars — for example Aldebaran and Betelgeuse – since they regarded single stars as representing people and animals. Many of the original meanings of the names had been forgotten even in Al-Sufi’s time, but some were direct translations of Ptolemy’s descriptions. For example, the star name Fomalhaut (in the constellation of Pisces) comes from the Arabic for "mouth of the southern fish," which is how Ptolemy described it in the Almagest .
