u/I_like_animals_

I didn't know where to ask but I decided this place would probably be appropriate, I am planning on making an art piece for my best friend for his birthday based off two planets to represent us (he's a mythology buff so I thought it fitted), the thing is while trying to research how mythologies depict the planets for this project I keep getting stupid inconsistent stuff mainly from astrology fans, so I came here in hopes of some clear awnsers, thank you.
