So to start this I feel that there are a lot of misconceptions about zodiacs. What I mean is you probably here people ask what is your zodiac sign and respond along the lines of "oh I'm a Leo/Capricorn/Pisces/etc", but there's actually a lot more to it. So I'll try to make the brief. The sign that most people know is your star sign, but there's a lot more. So pretty much I'm going to list them, and tell you what they are.
Sun sign-basic you
Moon sign-inner self
Rising sign-public you( (what you portray to strangers)
Venus sign-you in a relationship
Mars sign-dealing with your passions
Mercury sign-communication/how you plan things out
Saturn sign-limitations
Jupiter sign-luck
Neptune sign-deep inner self/spirit
Uranus sign-how you change
Pluto sign-your power
———————Chances are you probably don't know them all, but a little research can tell you.
For example my sun sign is Virgo, my moon sign is Pisces, and my rising sign is Capricorn.Edit: The meanings are a bit more then this, but this is simplified.
