Joan Jett’s birth chart
Born 22 September 1958, at Lankenau Medical Center, Pennsylvania. StarMap has no verified birth time yet.
Virgo Sun · Moon in Capricorn or Aquarius
Joan Jett’s zodiac sign and chart, in brief
22 September 1958 was a Monday: the day Joan Jett was born at Lankenau Medical Center, Pennsylvania. That makes Joan a Virgo. The Moon left Capricorn for Aquarius at about 12:05 local time, which leaves the Moon sign open without a birth time. Joan turns 68 in 2026. No verified birth time is on file for Joan; the chart is cast for midday, without houses.
Earth carries the most weight: four of the nine planets whose sign does not depend on the birth time, against fire two, water two and air one. Mutable signs hold six, fixed signs three and cardinal signs none. Virgo holds a stellium, four planets in one sign: Sun, Mercury, Venus and Pluto. No two planets sit closer to an exact angle than Jupiter and Pluto: a sextile, exact to a tenth of a degree. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Every planet was moving direct. The Moon was waxing gibbous, between first quarter and full.
StarMap's dataset holds 16 other people born on 22 September, among them Andrea Bocelli, Thiago Silva and Tom Felton. Andrea Bocelli was born on the very same day.

Joan Jett’s Sun, Moon and rising sign
Sun sign
Virgo
about 29° Virgo at midday
A Virgo Sun refines. Joan Jett is likely to notice what could be better and quietly make it so, keeping the highest standards for themselves. The art of this placement is knowing when good enough is the wiser choice.
Moon sign
Capricorn or Aquarius
Capricorn until about 12:05, then Aquarius (local time). Which one depends on a birth time StarMap does not have.
Born before about 12:05: Moon in Capricorn
A Capricorn Moon feels responsibly. With it, Joan may hold themselves together for other people, and can be hard on themselves when they cannot. This Moon tends to be restored by accomplishment, by structure, and by the rare person allowed to see them tired.
Born after about 12:05: Moon in Aquarius
An Aquarius Moon feels from a step back. Joan is likely to understand an emotion better than they inhabit it, and to need space and ideas to process. For this Moon, friends are family and freedom is security.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Lankenau Medical Center, Pennsylvania, at each hour of the day.
Joan Jett’s rising sign, by birth time
StarMap has not verified a birth time for Joan yet. It shows a birth time only when Astro-Databank rates it AA, A or B on the Rodden scale (AA from a birth certificate or record, A from the person, someone close to them or a news report, B from a biography). Until then, this is the rising sign for every possible time of birth on 22 September 1958, computed for Lankenau Medical Center, Pennsylvania.

Joan Jett’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Joan Jett’s private life.
A Virgo Sun finds purpose in being useful and doing a job properly, and Joan Jett's energy tends to stay steady as long as there is a task worth doing well. Rest is the hard part, because it can feel undeserved until everything is fixed. Typically a piece of work is still being adjusted long after everyone else would call it finished.
Moon in Capricorn or Aquarius
Capricorn until about 12:05, then Aquarius
needs and habits
Born before about 12:05: Moon in Capricorn
With the Moon in Capricorn, Joan's comfort probably comes from accomplishing something concrete each day, and an unproductive day can leave them oddly unsettled even on holiday. Harder feelings tend to be kept for when they are alone. Before rest is allowed there is usually one more thing to tidy, organise or finish.
Born after about 12:05: Moon in Aquarius
An Aquarius Moon processes daily feelings by stepping back and thinking them through rather than sitting inside them, and Joan is likely to need a degree of independence built into any close relationship. The temptation is to analyse a feeling instead of simply having it. Even after a good day with people, this Moon needs time alone to recover.
For Joan, Mercury in Virgo points to thinking that is precise and attentive to detail, and to clear communication, because the facts have usually been checked first. The catch is fixating on a small error and losing sight of the larger point. This is the placement that edits a message three times before sending something everyone else would have sent in one go.
With Venus in Virgo, Joan is likely to love through small, practical acts of service and to value competence and reliability in a partner. People with this Venus tend to be hardest on those they love most, and can mistake giving notes for giving care. They may try to fix a partner's problem before simply listening to it.
With Mars in Gemini, Joan is likely to act through words, argument and quick manoeuvring rather than force, and anger to come out sharp and verbal. Arguments can be won without the conflict underneath ever being resolved. A disagreement can still be under debate long after the other person just wants it to end.
Jupiter in Scorpio
2° Scorpio 54' at midday
growth and excess
Jupiter in Scorpio grows by facing what is difficult rather than avoiding it, even when that is the harder road at the time. The overreach, for Joan, may be an intensity that turns a manageable situation into an all-consuming one. The resilience tends to be noticed only after the hard part is over.
Saturn in Sagittarius builds discipline around belief and meaning, testing a big idea hard before committing to it. In front of people who might challenge a conviction, Joan is likely to hedge. Over time, someone with this Saturn often becomes a credible voice on the very questions they once felt they had no right to answer.
Uranus in Leo
14° Leo 46' at midday
freedom, generational
Joan shares Uranus in Leo with a generation, one that redefines self-expression and individuality, often through forms of creativity and visibility that were not available before. Closer to home, it suggests being comfortable with being seen in ways older relatives find unfamiliar.
Neptune in Scorpio
3° Scorpio 14' at midday
imagination, generational
Neptune in Scorpio marks a long season that Joan shares with many people of a similar age. Its imagination is drawn to the hidden, the taboo and the transformative, with a wider cultural fascination for secrets and endings. In an individual that can be a pull towards mystery for its own sake.
Pluto in Virgo
2° Virgo 55' at midday
power, generational
Pluto in Virgo is shared by Joan and many people born in the same span of years. That generation lives through deep change in work, in how services are organised, and in daily life itself. In one person that can be intensity around control, order and how much any one system can carry.
Aspects in Joan Jett’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Jupiter sextile Pluto
about 0.0° at midday
Meaningful growth without constant upheaval is what Jupiter sextile Pluto describes, with Joan Jett's sense of possibility and depth working in concert. The opportunities that matter tend to come at a manageable pace, not all at once in a way that would be hard to absorb.
Jupiter conjunction Neptune
about 0.3° at midday
For Joan, growth is likely to be idealistic and compassionate, a matter of causes, beliefs or visions bigger than daily concerns. Jupiter conjunct Neptune supplies the inspiration and leaves them the job of checking a beautiful idea against what can be achieved.
Sun trine Mars
about 1.2° at midday
Confidence and drive move in the same direction for Joan, so they are likely to act on their goals with very little inner resistance. The energy of a Sun-Mars trine is uncomplicated, and other people notice it and often want to be near it.
Mercury square Saturn
about 1.3° at midday
Self-doubt can get into thinking when Mercury is square Saturn, in the form of over-editing or delaying a decision that was ready. Sharing the unfinished thought anyway, again and again, is what loosens the doubt's hold over what Joan is willing to say out loud.
Mercury conjunction Venus
about 2.2° at midday
Mercury conjunct Venus ties Joan's thinking closely to what they love, so they probably talk about affection and beauty with ease. It lends a diplomatic, pleasant way of putting things, especially when the subject is close to the heart.
Mars square Pluto
about 2.6° at midday
With Mars square Pluto, Joan's drive can turn into a fight for control, whether the opponent is within them or is someone who resists them. When they redirect that intensity into the work itself, the friction becomes lasting strength.
The rest, listed without a reading. Those between Uranus, Neptune and Pluto hold for years at a time, so everyone born while one holds shares it.
- Neptune sextile Plutoabout 0.3°
- Venus square Saturnabout 3.5°
- Saturn trine Uranusabout 5.0°
