Quizplus · Accepted Answer

The modern definition of a constellation is a region of the celestial sphere, which is an imaginary sphere surrounding Earth where all the stars and celestial objects appear to be located. Constellations are defined by their boundaries, which were established by the International Astronomical Union in 1930. Each constellation is named after a mythological figure, animal, or object that is associated with the region it covers on the celestial sphere.
