What I know about the planets:
Sun=Sol, Roman God of the Sun...counterpart of Greek god Helios and often confused with Apollo
Mercury=Roman counterpart of Hermes, the messenger god, god of trickery, god who invented the lyre...
Venus=Who doesn't know who she is?
Mars=Roman god of war, representing the brutality of war in contrast to Athena/Minerva's focus on war strategies
Jupiter=Zeus, father of gods and men, husband of Hera/Juno, youngest among his siblings, cared for by the Hyades as a child, god of marriages, who rules from his throne in Mount Olympus, thought by the Greeks to be the highest mountain in the world, father of Perseus, Hercules, and many other Greek heroes...
Saturn=or Cronus, the father of Zeus/Jupiter and husband of Rhea who swallowed his sons when they were born to keep any from taking his throne
Uranus=or the Greek Ouranus, he was father sky, the husband of Gaea and father of the titans and the hundred-handed monsters
Neptune=Poseidon; the god of the sea, brother to Zeus, Hera, Hestia, Demeter, and Hades, husband of Amphitrite
So you see, I really don't know much about the planets themselves
