An arbitrary grouping of stars which form a pattern The sky is divided into 88 constellations These vary in size and shape from Hydra, the sea monster, which is the largest at 1,303 square degrees, to Crux, the cross, which is the smallest at 68 square degrees
A designated region of the sky containing a pattern of stars identified by name The entire sky surrounding the earth is divided into 88 constellations named after mythological figures, animals, and objects Each constellation occupies a region of the sky containing that star pattern Each season different constellations are visible in the sky from any given location
A cluster or group of fixed stars, or division of the heavens, designated in most cases by the name of some animal, or of some mythologial personage, within whose imaginary outline, as traced upon the heavens, the group is included
A grouping of stars that make up patterns named for historical, mythological, or other figures in the sky The sky is divided up into 88 such constellations
A group or arrangement of stars as seen from Earth Stars in a constellation may appear close together in our sky but in fact may be varying distances away from us Constellations are usually named after Greek mythological chartacters
A constellation is a group of stars which form a pattern and have a name. a planet orbiting a star in the constellation of Cepheus. Any of certain groupings of stars that were imagined by those who named them to form images of objects, mythological figures, or creatures in the sky. They are useful in helping sky gazers and navigators locate certain stars. A constellation's stars are often designated by its name and letters of the Greek alphabet in order of brightness. Of 88 named constellations in Western astronomy, about half retain the names Ptolemy gave the 48 he identified in his Almagest. See also zodiac
one of 88 sectors into which astronomers divide the celestial sphere; many constellations are named after a prominent group of stars within them that represents a person, animal, or legendary creature from ancient mythology
A pattern of stars on the sky, named for a person, animal, or object (usually from mythology) Astronomers use constellations to designate directions in space; for example the great galaxy "in Andromeda" lies in the direction from us marked by the pattern of stars we call Andromeda (the Princess of Ethiopia in Greek mythology) Just as patterns we see in the clouds are not permanent, neither are the star-patterns of constellations, since the stars move (albeit very slowly on the timescale of a human lifetime) The constellations of 100,000 years ago were quite different from today's Astronomers now divide the sky into 88 sectors, each of which is named after the traditional constellation in that sector
Constellation refers to the network of orbiting global navigation satellites, with deference to their relative positions The pattern created by the relative positioning of a navigation satellite network is designed to achieve a very high probability of global satellite coverage even in the event of satellite outages
