Jupiter's sign in the birth chart shows how a person learns, what they believe and how they give advice. It also shows how easily wealth, children and good teachers come into the life.
Jupiter owns 2 signs, Sagittarius (Dhanu) and Pisces (Meena). It is exalted in Cancer at 5 degrees and debilitated in Capricorn at 5 degrees.
Jupiter spends about a year in each sign, so people born within about 12 months of each other often share a Jupiter sign. The Jupiter sign calculator finds yours from the date, time and place of birth. The planet itself is covered in Jupiter in Vedic astrology.

Which Signs Does Jupiter Rule?
Jupiter rules Sagittarius and Pisces, the 9th and 12th signs of the zodiac. Sagittarius from 0 to 10 degrees is its moolatrikona, and the rest of that sign counts as its own.
Sagittarius is a dharma sign, the sign of the teacher and of faith. Pisces is a moksha sign, the sign of devotion and liberation.
Brihat Parashara Hora Shastra (Chapter 2) names Vamana as the avatar of Vishnu that came through Jupiter. Vamana recovered the 3 worlds from Bali by asking for 3 steps of land, and that ties Jupiter to wisdom used for dharma.
Jupiter counts the Sun, the Moon and Mars as friends, Mercury and Venus as enemies, and Saturn as neutral. These planetary friendships decide how comfortable Jupiter feels in each sign.
Which Sign Is Best for Jupiter?
Jupiter is strongest in Cancer, its sign of exaltation, and next in Sagittarius and Pisces. It is also comfortable in the signs of its friends: Aries and Scorpio of Mars, Leo of the Sun, and Cancer of the Moon.
Capricorn is its weakest sign. Taurus and Libra belong to Venus, and Gemini and Virgo to Mercury, so Jupiter works harder for its results in those 4 signs.
In Cancer, Sagittarius or Pisces, Jupiter forms Hamsa Yoga when it also sits in a kendra from the ascendant. Hamsa is one of the Pancha Mahapurusha yogas, and it gives a learned and respected person.

Jupiter in Aries (Mesha)
Mars, Jupiter's friend, rules Aries. Jupiter here gives principled courage, and the person acts quickly on what they believe is right.
Leadership in teaching, law or any cause with a clear principle suits this placement, especially when Mars is also well placed in the chart. Impatience with slower learners is the part to watch.
Jupiter in Taurus (Vrishabha)
Taurus belongs to Venus, one of Jupiter's 2 enemies. Jupiter here turns its wisdom toward wealth, food, family values and things that last.
Financial judgement is often sound, and savings tend to grow steadily over the years. Comfort can slow the search for meaning, so a regular habit of study or giving keeps this Jupiter active.
Jupiter in Gemini (Mithuna)
In Gemini, Jupiter sits in Mercury's sign, the 7th from its own Sagittarius. Learning becomes broad and verbal, with interest in many subjects and languages.
Mastery of one subject is what gives this Jupiter its authority. Its own nakshatra, Punarvasu, begins at 20 degrees Gemini.
Jupiter in Cancer (Karka)
Cancer is Jupiter's sign of exaltation, with the peak at 5 degrees. The Moon rules it and is Jupiter's friend, so wisdom and care come together here.
People with this placement often teach, counsel or protect, and they are trusted for sound judgement. Wealth, children and the blessings of elders tend to arrive with less struggle.
Jupiter in Leo (Simha)
The Sun owns Leo, and Jupiter counts it a friend. Jupiter here gives dignity, a strong sense of duty and the manner of a respected advisor to those in power.
Government, administration and senior teaching roles suit it, and the person is often trusted with decisions that affect many people. Pride in one's own beliefs is the thing to watch.
Jupiter in Virgo (Kanya)
Virgo is Mercury's sign and falls 7th from Pisces. Jupiter here thinks in detail, and its wisdom shows in method, analysis and careful service.
Research suits it. So do audit and editorial work. Doubt can grow strong in this sign, and a devotional practice steadies it.
Jupiter in Libra (Tula)
Libra belongs to Venus, the guru of the asuras, so here the guru of the gods works in the other guru's sign. Jupiter in Libra gives fairness, diplomacy and a gift for counsel in partnerships and law.
Advice from this placement weighs both sides with care. The pull toward approval can soften firm judgement, so clear principles help. Vishakha, another of Jupiter's nakshatras, begins at 20 degrees Libra.
Jupiter in Scorpio (Vrishchika)
Mars, a friend of Jupiter, rules Scorpio. Jupiter here looks for hidden knowledge through research, psychology, occult study or inherited wisdom.
Faith is tested through crises and grows stronger after each one. Using that knowledge for others, through teaching, counselling or research they can apply, is the constructive side of the placement.
Jupiter in Sagittarius (Dhanu)
Here Jupiter is in its own sign, and in its moolatrikona for the first 10 degrees. It gives learning, faith and respect for dharma without borrowing from another planet.
Many with this placement become teachers, priests, judges or guides. A strong Jupiter often ignores advice when young, and its wisdom then arrives through experience.
Jupiter in Capricorn (Makara)
The debilitation of Jupiter falls in Capricorn, deepest at 5 degrees. Saturn rules the sign and stays neutral to Jupiter.
Wisdom here turns practical, and faith is judged by what it produces.
Cancellation of the debilitation is possible. One route is Saturn in a kendra from the ascendant or the Moon, and another is the Moon in a kendra from the ascendant. The conditions are set out in Neecha Bhanga Raja Yoga.
Jupiter in Aquarius (Kumbha)
Aquarius is Saturn's other sign, and Jupiter treats Saturn as neutral. Jupiter here gives its wisdom to groups, causes and the common good.
Teaching large numbers of people, charitable work and community service suit it, often through an organisation built to serve a public cause. Its ideals are broad, and warmth toward individuals may need attention. Purva Bhadrapada, the third of Jupiter's nakshatras, begins at 20 degrees Aquarius.
Jupiter in Pisces (Meena)
Pisces is Jupiter's other sign. Its wisdom turns toward devotion, compassion and charity, and the person gives without keeping count.
Spiritual practice, pilgrimage and the teaching of scripture suit it, along with charitable work done without any wish for credit. Clear limits keep that generosity from being misused by others.
Jupiter's Nakshatras
Jupiter rules 3 nakshatras: Punarvasu, Vishakha and Purva Bhadrapada. Each starts at 20 degrees of one sign and ends at 3 degrees 20 minutes of the next. Together they cross Gemini and Cancer, Libra and Scorpio, and Aquarius and Pisces.
A birth with the Moon in one of them starts in Jupiter's Mahadasha. The Moon's degree sets how much of its 16 years remains.
Reading Your Jupiter Sign
The sign is the first layer. The house comes next, since the sign shows how Jupiter's wisdom works and the house shows where it is used. The house readings are in Jupiter in the 12 houses.
Jupiter also casts full aspects on the 5th, 7th and 9th houses from itself, so its sign colours 3 more houses. Combustion and a conjunction with Rahu both weaken its judgement, and a Jupiter that holds the same sign in the Navamsha gains strength.
Jupiter's transit through the signs is read from the Moon sign, and the dates are on the Jupiter transit page. A personal consultation weighs the sign, house, aspects and dasha together in one chart.
Summary
Jupiter's sign shows how a person learns, believes and advises others. Jupiter rules Sagittarius and Pisces, is exalted in Cancer and debilitated in Capricorn, and stays about a year in each sign.
Its friends are the Sun, the Moon and Mars, so it is comfortable in Aries, Leo, Scorpio and Cancer. Mercury and Venus are its enemies, and Taurus, Gemini, Virgo and Libra ask more of it. Read the sign with the house, aspects, Navamsha and dasha before judging Jupiter.
