Later, the names of these constellations spread to Greece. The Greeks combined their own legends to fabricate many fairy tales, which further enriched the constellations. There were 48 constellations at that time. In modern times, the west has added some new constellations and fairy tales. Later, IAU decided to divide the stars into 88 constellations. They appear in the night sky in four seasons: spring, summer, autumn and winter.
