Personally, my favourite planet is Saturn (and no, I don't mean the car). I like it because it's unique. I know that Jupiter has rings, but you can't see them, and they're not it's signature thing. With Saturn, everyone recognizes it for it's rings. I'd like to say that I have something that everybody recognizes me for, that no one else has. I guess I'm unique in a way that I'm not like anyone else. But, if I had to relate to a planet, I'd say Earth, because I'm the only one that has intelligent life. That was a joke by the way.
