Urania is a character in mythology, as well as an an asteroid If you go to the chart construction pages at Astrodienst
www.astro.com you can input Urania in your chart. In my chart Urania conjuncts Venus.
That's in keeping with the opinion of most modern-day astronomers that astrology is too minor a subject to consider its Muse, Goddess of the Heavens, as important enough to associate with a Planet.
There was a strange disconnect in the Planet's naming what it was named. As the story goes, they wanted to follow the partial pattern of son-to-father (Mars>Jupiter>Saturn>Caelus). I say partial, because it leaves out the first two Planets of the sequence, Mercury and Venus; and, in retrospect, the naming of Neptune and Pluto.
All right, fine. But here's where something's amiss. They also wanted Roman, not Greek names. Simple enough, name it "Caelus", just as Zeus is named "Jupiter". Instead, they refer back to the Greek prefix "Uran", meaning "of the Heavens", and further complicate things by attempting to make it SOUND Latin rather than Greek, by changing "Uranos" , or "Ouranos", to "Uranus".
I consider that fortunate, because by inexplicably emphasizing "Uran", they included the Muse Urania in that category.
Btw, how is the "Goddess of the Heavens", granddaughter of Uranos, and daughter of Sky-god and King Zeus and Mnemosyne, goddess of Memory, just a minor "character"? Remember, she appears AFTER the demise of Uranos/Caelus, the only no-longer-relevant Greco-Roman deity in ancient times which is associated with astrology. Meaning, he was no longer a player in the affairs of the gods themselves.
If you're looking for Urania to have taken part in godly shenanigans, remember, as Goddess of the Heavens, she was "above it all".
