The celestial body you can see in the night sky named after the Greek god of the sky is Uranus.

While Uranus is named after the Greek god of the sky, Ouranos, the name itself is a Latinized version of the Greek name.

It's important to note that Uranus is a planet, not a star. It's the seventh planet from the sun, and it's visible to the naked eye under dark skies, although it appears as a dim, bluish-green point of light.
