Planets in Signs
Jupiter governs growth, luck and belief, and Libra is an air sign in cardinal mode. Here is what the placement does, its shadow, and the real dates Jupiter is in Libra.

Jupiter spends about a year in each sign, so anybody born in the same window shares the sign with you. What makes it yours is the house it falls in and the aspects it makes to the rest of your chart. This page is about the sign. The other half needs your birth time.
Before the sign, the planet. Jupiter rules growth, luck and belief. The question it keeps asking is where do I expand. Wherever Jupiter sits in a chart is the department that question gets answered in.
Libra is an air sign, which describes what it cares about, and cardinal, which describes how it goes about things. Air needs to understand it before it can want it. Cardinal signs start things.
Jupiter is neither dignified nor debilitated in Libra. It neither rules the sign, nor is exalted in it, nor is in detriment or fall. In traditional terms that is called peregrine, and it means the planet is working without any particular advantage or handicap: it simply takes the character of the sign it is in. Most placements in most charts are like this, which is worth saying because pages that describe every placement as either blessed or cursed are not describing astrology.
Where life keeps handing you more than you asked for, run through Libra. In practice that tends to look like fair, charming and diplomatic, applied specifically to growth, luck and belief, rather than to everything you do.
Libra's keyword is "I balance", and the version of that which belongs to Jupiter is narrower than the sign description you will have read elsewhere. Somebody with Jupiter in Libra and very little else in the sign is not a Libra person. They are a person who handles growth, luck and belief the way Libra does.
More of whatever Libra counts as good, which here is something that can be talked about, understood, and turned over with somebody else. Jupiter does not moderate; it enlarges whatever it touches, including the sign's blind spots.
And what it finds hard: knowing when enough has arrived. Keeps the peace at its own expense, enlarged, which is a specific kind of trouble.
Jupiter returns to Libra on a regular cycle. These are the real dates, computed from an ephemeris rather than copied, so you can check your own birth date against them.

This is the part most planet-in-sign pages leave out, and it is why two people with the same placement can recognise almost nothing of each other in it. Jupiter in Libra in the tenth house is a public thing. The same placement in the twelfth is nearly invisible, including to the person who has it.
Which house it lands in depends on your rising sign, which depends on your birth time. The rising sign pages set out the whole structure, and the table there shows which house Libra occupies for each of the twelve.
| Planet | Jupiter |
| Sign | Libra |
| Element and mode | Air, Cardinal |
| Sign ruled by | Venus |
| Essential dignity | None. Neither dignified nor debilitated here |
| Needs a birth time | Rarely for the sign, always for the house |
The same planet in the signs either side is the sharpest comparison available: Jupiter in Virgo and Jupiter in Scorpio. And the libra decans narrow a thirty-degree sign down to ten, which is three times more specific than the placement on its own.
Jupiter governs growth, luck and belief, so in Libra it handles that department in a Libra way: fair, charming and diplomatic.
It is neutral, or peregrine: Jupiter neither rules nor is exalted in Libra, and is neither in detriment nor fall. It simply takes on the character of the sign. Most placements are like this.
Not for the sign itself, which Jupiter holds for a year in each sign. You do need one for the house it sits in, and the house is half the meaning.
Overcommitting, then resenting the commitment, shaped by Libra's tendency to keeps the peace at its own expense.
