* Ouranos is the primordial god of the sky, the son of Gaia (Earth) and the father of the Titans. He is often depicted as a giant figure holding the heavens up.
* Orion is a giant hunter who was placed in the sky as a constellation after his death. He is associated with the constellation Orion, which is one of the most prominent and recognizable in the night sky.
The only connection between the two is that Orion was said to have been born from the urine of Zeus and Hera, which fell on the ground and was transformed into a giant baby by Gaia. This is a very roundabout connection and does not make them the same entity.
