Jupiter
Jupiter in a birth chart is growth, belief and generosity: where life opens up for you, what you trust, and how you make your own luck. It spends about a year in each sign.
Somebody once said yes before you had finished asking, and something that had been shut opened out. Jupiter is that door: the expectation that things will open, and the surprise of how frequently they do.
In your chart
The sign shows the style of your optimism: generous in Sagittarius, warm in Leo, scholarly in Gemini. Its house is where you expand and find that life meets you halfway, and where you learn most easily. Aspects show what faith attaches to. A trine to the Moon is feeling at home in the world; a square from Mercury is a mind that takes on more than it can finish.
From a real analysis
In her chart: Jupiter in Cancer, in the 9th house · 15°57′ Cancer
Jupiter, the planet of luck and belief, sits in Cancer, the sign of caring for your own, and Cancer is said to be where Jupiter is exalted, its generosity at its warmest when it looks after family. You believe in people the way a good parent does, and that belief sits right at the top of your chart, in how you are seen at work (blending, close at 1.3°): you are known for making a group feel cared for. It works hand in hand with your power to change things, so your kindness has real reach.
Themes
Jupiter is belief, learning, travel, humour, hospitality and the wish for more: more meaning, more room, more of the people you love. It is the friend who says go, the good teacher, the generous host, and the traveller who comes home with a story and a recipe. A prominent Jupiter believes in the next chapter, and is right enough of the time to keep going.
Excess is the danger: the promise made in a good hour, the second helping, the plan that outgrows one person. Jupiter needs a limit, which Saturn supplies, and the pair together are the balance of hope and restraint.
Twelve months a sign
The largest planet needs just under twelve years to lap the Sun, and so spends about twelve months in each sign. Everyone born in the same year shares it, which leaves its house and aspects as the personal part. Retrograde about four months of each year, it is turned back in around a third of charts, and the tradition reads that as belief formed privately rather than received.
Sagittarius and, traditionally, Pisces are its signs; Cancer, at 15°, is its exaltation; its joy is the eleventh house, the house of friends. The old writers called it the greater benefic.
How the analysis treats it
Jupiter’s chapter names sign, degree, house, every aspect and any retrograde, and is read as where your confidence grows and what it grows into.
Your chart places Jupiter to the minute of its sign, and the analysis names it by its degree, its sign and its house. When it was retrograde at the moment of birth, the chart marks it with an R.

Your Jupiter
That is Jupiter in everyone’s chart. Yours stands in one sign and one house, and those two say what it means for you. Free, and it takes a minute.
