Who named the constellations

From the earliest times people arranged conspicuous stars in the night sky into patterns in which they believed they could see figures of living beings, gods or objects. For example, the 12 well known constellations which make up the zodiac date back to the Babylonians. Most of the other constellations in the northern sky have their origins in Ancient Greece. Two thousand years ago, Eratosthenes and Ptolemy wrote of 48 constellations, most of the names of which were taken from Greek mythology. More recently more constellations previously unknown to Europeans have been introduced, especially in the Southern Hemisphere, so that the heavens are now home to creatures such as the Bird of Paradise and the Chameleon as well as all manner of technical equipment such as the Air Pump and the Chemical Furnace. In 1928, the International Astronomical Union finally drew up the list of 88 constellations and their boundaries, which is still in use today.
