What's up with those sun/moon/star/venus/mercury/mars signs?

you mean your astrological sign? those are just new ones. I like the Chinese ones.

People look to that stuff too much. They need something for hope and ideas. And maybe sometimes it comes true only because you worked for it. But didn't know it.

You need the year, place and time of birth too to get a complete chart of your life and planetary positions in your sign at the time of your birth.

Hey Arleney, how is it going? Oh me? I'm good, I'm good, haha. Well, you kind of need to know where and what time you were born, and then there are free birth charts and what not on cafe astrology, but the star signs could be argued to be most important. Your star sign is supposedly the core of yourself. It's the real person you are. Don't worry though, I think everyone isn't limited to what their star sign is. I personally believe it's just something fun, but not something to be taken seriously. Good luck.
