In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms (which themselves are generally referred to in non-technical language as "constellations"), which are patterns formed by prominent stars within apparent proximity to one another on Earth's night sky.

In 1922, the IAU in divided the celestial sphere into 88 official constellations. Where possible, these modern constellations usually share the names of their Graeco-Roman predecessors, such as Orion, Leo and Scorpius. Out of the 88 modern constellations, 36 lie predominantly in the northern sky, and the other 52 predominantly in the southern.
