* Ancient Origins: Pegasus has been recognized as a constellation for thousands of years. It appears in ancient Babylonian star catalogs, and its name comes from Greek mythology.
* No Recorded First Observation: Early civilizations likely noted constellations simply for navigation and calendar purposes, not for formal recording. There is no record of a "first sighting" of Pegasus.
* Universal Visibility: Pegasus is a prominent constellation in the Northern Hemisphere's autumn sky. It's likely that many cultures around the world observed it independently and incorporated it into their own mythology and star lore.
So, while we don't know the exact moment of its first sighting, we can say that Pegasus has been recognized as a constellation for a very long time, dating back to ancient times.
