In Greek mythology, the stars were placed in the sky by the god Uranus, the primordial god of the sky. He is often depicted as a personification of the heavens.

Here's a bit more about Uranus's role:

* He is the father of the Titans, a race of powerful deities.

* His wife, Gaia (Earth), gave birth to the first stars, which were her children.

* Uranus placed these stars in the sky as a way to illuminate the darkness and mark the celestial sphere.

It's important to note that this is just one interpretation from Greek mythology. Other myths and stories offer different explanations for the placement of the stars.
