Hey there
Yeah, reading about astrology online can come off pretty fragmented. Synthesis of the information is probably the most important thing to achieve.
"What? How? Where?" is a good place to start.
What? - The planet.
How? - The sign.
Where? - The house.
After blending that together, it's good to look at aspects considering what we already know from What?How?Where?
What do we know?Do we know things? Let's find out.
Your Chart:
Sun in Gemini in 9th
Sun is the soul, self, and core being (what). Your core being exemplifies the traits associated with Gemini (how), and you show yourself in the pursuits of the 9th house (where). Traits associated with Gemini include intellectual exercise and a dilettante approach to subject matter. The 9th house is associated with philosophy and higher learning along with long travels. Therefore, it is a core element of your being to pursue adventure and intellectual exercise in an open and logical way.
Moon in Virgo in 11th
Moon is the emotions and family ties, placed in Virgo, which is grounded in orderliness, and located in the 11th house, having to do with friendships and group activities. Therefore, you relate emotionally by doing practical things for others, and most of your friends and close ones share hobbies and associations of yours rather than distinct character traits.
Mercury in Gemini in 9th
Mercury is your intellect, at home in Gemini, meaning you're a sharp one, nicely placed in the 9th. Completely smooth. You're a smarty and everyone knows it.
Venus in Taurus in 8th
Venus is love and romance, and also what comes easily and naturally to you. Yours is located in the 8th house of intimacy (sex, and death), and in the fixed, no nonsense sign of Taurus. Sex (good, earthy, emotional), may truly be the way to your heart. You probably couldn't mesh well with someone who was shy or didn't want to open up fully in that arena.
Mars in Virgo in 11th
Mars is action, aggression, and achievement (also, the physicality of your sexual nature), placed in Virgo, and located in the 11th. Mars in Virgo usually results in conscientious people in a work place: trustworthy, timely, and such. You go after the things you want in a timely and trustworthy manner. Sexually, Mars in Virgo can point to a kinky person, the Venus often indicating top or bottom. This is all in the 11th house, which would indicate someone involved in many organizations, kinky or otherwise.
Jupiter in Sagittarius in 3rd
Jupiter is expansion and luck in Sagittarius, the planet it rules, and in the 3rd house of communication. Perhaps you're good at writing. Any and all types of communication; maybe you're a great counselor of some sort.
Saturn in Pisces in 6th
Saturn is restriction and hard lessons, the planet placement is less important because this placement is generational, and it's located in the 6th house of daily work. Perhaps it's difficult for you to get right down to business. You procrastinate. Maybe you have attention issues. Maybe you're a perfectionist (Mars in Virgo), and you wrestle with that when it's time to start working (Saturn in 6th). The 6th house is also health, so maybe your work is very unhealthy for you.
Uranus in Aquarius in 4th
Uranus in 4th; lots of moving either in childhood or in adult life. "Home" is not a specific or particular place for you, in your mind.
Neptune in Capricorn in 4th
Neptune in 4th; Fantasy and delusion meets the house of family and childhood occurrences. Your childhood may have been magical.
Pluto in Scorpio in 2nd
Transformation to your finances. You start from the bottom. Now you're here. ..and you may go back again. And do it again.
Now, aspects just clarify these.
Mercury
conjunctSun in Gemini in 9th
A conjunction signifies action, but in a neutral way. There will be good or bad, depending on the situation. This placement is basically saying your core self works closely with your intellect, which is all Gemini (obviously intelligent) doing obviously intelligent things (chillin out in the 9th, with philosophy and such.)
Sun in Gemini in 9th
opposing Jupiter in Sagittarius in 3rd
An opposition signifies action, but with tension, i.e. negative way. So, the self is in tension with expansion = you overdo it. This points to indulgence. Maybe you spend too much of your time with your nose in books or the interwebs. Go "do" instead of "learn".
I'm gonna do a positive aspect, and then give it a rest, because you should totally be able to go through the rest of your chart with these as examples.
Venus in Taurus in 8th
sextile Saturn in Pisces in 6th
A sextile is harmonious, and may not signify action, but a feeling. Things go smoothly with it. Your sense of romantic connection (Venus) is harmonious with hard work and hard lessons (Saturn) = you've got a practical sense of what it takes to make a relationship work, especially the daily component (6th house), i.e. "I'll help her/him/them with planning/other very practical things they need."
