Okay. Here's the breakdown of the gods that the planets were named after.

Jupiter - Roman god of lighting, aka Zeus in Greek mythology
Mercury - Roman god of merchant trade (hence the word, 'merchant'), also known as Hermes to the Greeks
Mars - Roman God of war, Ares in Greek mythos
Venus - Roman Goddess of Love, aka Aphrodite in Greek mythos
Saturn - Roman God of Time, aka Chronos
Pluto - Roman God of the Underworld, or dead, aka Hades
Uranus - Greek God of Skies, aka Caelus to the Romans
Neptune - Roman God of the Seas and Earthquakes, aka Poseidon in Greek mythos

And, if by Uranus' power, you mean her attack, "World Shaking," it's probably derived from the nickname "World Shaker" for Neptune, due to his control of Earthquakes.
