Here's a breakdown:
* Stars in Orion: The stars that make up Orion are billions of years old, some even older than our sun.
* Orion as a constellation: The pattern we recognize as Orion has been observed and given meaning by humans for thousands of years. There are records of Orion in ancient Babylonian, Egyptian, and Greek cultures.
So, Orion itself is not a specific age, but rather a pattern that has been recognized and given meaning throughout human history.
