Capricorn Sun · Moon in Cancer or Leo
J. K. Simmons’s zodiac sign and chart, in brief
9 January 1955 was a Sunday: the day J. K. Simmons was born in Detroit, Michigan. Their zodiac sign is Capricorn. The Moon left Cancer for Leo at about 04:40 local time, which leaves the Moon sign open without a birth time. They turn 71 in 2026. StarMap has not verified a birth time yet, so the chart is cast for midday on that date and has no houses.
Of the nine planets whose sign does not depend on the birth time, four are in water signs, two in fire, two in earth and one in air. By modality the count is five cardinal, two fixed and two mutable. Closest of the aspects is the trine between Mars and Uranus, about 0.1° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Jupiter, Uranus and Pluto were retrograde. Over the course of the day the Moon went from full to waning gibbous.
StarMap's dataset holds 22 other people born on 9 January, among them Simone de Beauvoir, Catherine, Princess of Wales and Joan Baez.

J. K. Simmons’s Sun, Moon and rising sign
Sun sign
Capricorn
about 18° Capricorn at midday
A Capricorn Sun endures. Ambition, patience and a dry sense of humour are what tend to carry J. K. Simmons up long slopes other people give up on. The placement learns, eventually, that rest is part of the climb.
Moon sign
Cancer or Leo
Cancer until about 04:40, then Leo (local time). Which one depends on a birth time StarMap does not have.
Born before about 04:40: Moon in Cancer
The Moon is at home in Cancer. For J. K. Simmons that points to feelings that are tidal, strong and closely tied to the people they love, and to a memory for how everything felt. This Moon is restored by home, by cooking, and by being needed.
Born after about 04:40: Moon in Leo
A Leo Moon feels with its whole heart and needs that to be noticed. Warm attention tends to fill J. K. Simmons up, and being overlooked can empty them faster than anything. Play, creativity and loyal friends usually bring them back to themselves.
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 Detroit, Michigan, at each hour of the day.
J. K. Simmons’s rising sign, by birth time

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 9 January 1955, computed for Detroit, Michigan.

J. K. Simmons’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about J. K. Simmons’s private life.
With the Sun in Capricorn, J. K. Simmons is likely to find purpose in building a reputation and a structure that will outlast them, with a vitality that is steady rather than showy. The trap can be measuring their worth by output alone. They may well work through tiredness instead of naming it, until someone else has to point it out.

Cancer until about 04:40, then Leo
needs and habits
Born before about 04:40: Moon in Cancer
With the Moon in Cancer, J. K. Simmons's needs tend to be tied to home, routine and the people they check in on daily. Small rituals are steadying: a particular meal, a particular chair. The tension is reading other people's moods so closely that those moods can be taken on without noticing.
Born after about 04:40: Moon in Leo
A Leo Moon needs warmth and acknowledgement worked into everyday life, not just on big occasions. A day with no one noticing can drain J. K. Simmons faster than a hard day with an audience. The mood tends to lift visibly the moment someone compliments something small J. K. Simmons did.
Mercury in Capricorn thinks methodically, and J. K. Simmons tends to communicate in a measured, practical way that people trust. The focus on a useful conclusion can be so strong that ideas which have not yet proven their worth are dismissed. J. K. Simmons will often get straight to the point in a conversation other people expected to be casual.
Venus in Sagittarius loves with enthusiasm and a need for shared adventure, and J. K. Simmons probably values a partner who gives them room to roam. When things get serious, this placement can confuse freedom with distance. The pattern with this Venus is to plan the next trip together before settling into the current one.
With Mars in Pisces, J. K. Simmons is likely to act indirectly, often through avoidance or quiet withdrawal rather than confrontation, and anger can turn into sadness before it has even been named as anger. The habit is to absorb conflict rather than address it. Often they need to leave a tense room before they can work out what they feel.
Jupiter in Cancer
25° Cancer 43' at midday ℞
growth and excess
For J. K. Simmons, Jupiter in Cancer means growing by nurturing others and building a home that people want to return to. The excess can be protecting loved ones past the point they need it. Generosity here takes the form of home-cooked meals, open doors and an instinct to take in anyone who needs somewhere to land.
Saturn in Scorpio builds its discipline around trust and control, and for J. K. Simmons letting go of either is unlikely to come easily. The doubt is bracing for betrayal even in relationships that have given no reason for it. Comfort with vulnerability can come in the end, and the work it takes is seldom seen by others.
Uranus in Cancer
25° Cancer 57' at midday ℞
freedom, generational
Uranus in Cancer belongs to an age group rather than to J. K. Simmons alone. Its mark is a generation that redefines home and family, departing from the structures the previous generation grew up inside. At the personal level it is read as a pull to build family life differently.
Neptune in Libra
28° Libra 07' at midday
imagination, generational
A whole generation has Neptune in Libra, J. K. Simmons among them. It idealises romantic partnership, often shaped by images of love on screen that outpace real relationships. The personal echo is a dreamy standard for what a relationship should feel like.
Pluto in Leo
26° Leo 23' at midday ℞
power, generational
Pluto in Leo is held by a whole generation, one that transforms ideas of individual power, leadership and fame. At a personal scale, for J. K. Simmons, it can be a charged relationship with authority and with who gets to hold the spotlight.
Aspects in J. K. Simmons’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.
Mars trine Uranus
about 0.1° at midday
J. K. Simmons's drive and originality tend to run together easily, which allows fast, inventive action when a situation calls for something different. Mars trine Uranus can make a bold move look natural, and it is carried off more often than the risk would seem to justify.
Mercury square Neptune
about 0.2° at midday
Wishful assumptions, or a compelling but unverified story, can blur thinking when Mercury is square Neptune. What helps J. K. Simmons is pairing imagination with a habit of checking the details before repeating the story as though it were settled fact.
Jupiter conjunction Uranus
about 0.2° at midday
Growth comes suddenly and by unconventional routes with Jupiter conjunct Uranus, and J. K. Simmons is likely to be drawn to opportunities that break from the expected path. Openness to change is the strength. Following through on one bold idea before moving on to the next is the discipline.
Mars trine Jupiter
about 0.3° at midday
Mars trine Jupiter lets drive and a sense of possibility work as one, and in J. K. Simmons's chart the pattern favours confident, well-timed action towards the goals that matter to them. A first move under this trine tends to open a door, largely because it is made with conviction and at a sensible moment.
Sun sextile Saturn
about 0.4° at midday
Steady, unglamorous effort is likely to feel worthwhile to J. K. Simmons rather than draining, because it fits their sense of who they are. Consistency probably comes more easily to them than they give themselves credit for, especially once they stop waiting for permission to claim it.
Mercury sextile Mars
about 1.9° at midday
Speaking up quickly and clearly when it matters comes easily to J. K. Simmons, since thinking and drive work in step. That plain directness serves them well in fast-moving conversations and quick decisions alike.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris.
