Martin Cooper’s zodiac sign and chart, in brief
Martin Cooper was born on Wednesday, 26 December 1928, in Chicago, Illinois. Their zodiac sign is Capricorn. The Moon was in Gemini until about 06:15 and in Cancer afterwards, so the Moon sign turns on the birth time. Martin turns 98 in 2026. StarMap has no verified birth time for Martin, so the chart is cast for midday and leaves the houses out.
Earth carries the most weight: four of the nine planets whose sign does not depend on the birth time, against fire two, air two and water one. Across cardinal, fixed and mutable signs the split is four, two and three. Closest of the aspects is the trine between Jupiter and Neptune, about 0.8° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Three planets were retrograde: Mars, Neptune and Pluto. The Moon was full.
StarMap's dataset holds 13 other people born on 26 December, among them Jared Leto, Hugo Lloris and Lars Ulrich.

Martin Cooper’s Sun, Moon and rising sign
Sun sign
Capricorn
about 4° Capricorn at midday
A Capricorn Sun endures. Ambition, patience and a dry sense of humour are what tend to carry Martin Cooper up long slopes other people give up on. The placement learns, eventually, that rest is part of the climb.
Moon sign
Gemini or Cancer
Gemini until about 06:15, then Cancer (local time). Which one depends on a birth time StarMap does not have.
Born before about 06:15: Moon in Gemini
The Moon in Gemini processes feeling by naming it. For Martin, talking, writing and switching perspective are likely ways to settle, and silence can make small worries loud. They probably need people who let them think out loud.
Born after about 06:15: Moon in Cancer
The Moon is at home in Cancer. For Martin 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.
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 Chicago, Illinois, at each hour of the day.
Martin Cooper’s rising sign, by birth time
StarMap has not verified a birth time for Martin 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 26 December 1928, computed for Chicago, Illinois.

Martin Cooper’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Martin Cooper’s private life.
With the Sun in Capricorn, Martin Cooper 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.

Gemini until about 06:15, then Cancer
needs and habits
Born before about 06:15: Moon in Gemini
The Moon in Gemini runs its daily habits on conversation and mental stimulation, and Martin is likely to settle by talking a worry through rather than sitting with it quietly. A day with no one to talk to can leave them restless. The habit is to message a friend the moment something comes to mind, before deciding what to think about it.
Born after about 06:15: Moon in Cancer
With the Moon in Cancer, Martin'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.
Mercury in Capricorn thinks methodically, and Martin 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. Martin will often get straight to the point in a conversation other people expected to be casual.
Venus in Aquarius loves as a friend first, and values independence, shared ideas and a partner who allows plenty of room. Martin may keep just enough distance that closeness feels slightly out of reach, even to them. This Venus can prize a partner's individuality more than the intimacy between them.
With Mars in Gemini, Martin 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 Taurus
0° Taurus 25' at midday
growth and excess
In Martin's chart, Jupiter in Taurus grows through patience, and what it builds tends to come together slowly and steadily rather than in one leap. Taken too far, that can become excess: holding on to more comfort or more stuff than serves them. They are probably generous with food, gifts and shared pleasures, and now and then generosity tips into indulgence.
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, Martin 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 Aries
3° Aries 33' at midday
freedom, generational
Uranus spends about seven years in each sign, so Martin shares Uranus in Aries with many people of a similar age. It marks a generation that pushes for change through direct, individual action rather than waiting for permission. In one life it can appear as impatience with the slow-moving institutions older generations built.
Neptune in Virgo
1° Virgo 14' at midday ℞
imagination, generational
Neptune moves slowly, so Martin shares its place in Virgo with people born years either side. The imagination of this generation turns towards service, craft and idealised routines of self-improvement. In one life it can mean chasing an impossibly perfect daily practice.
Pluto in Cancer
17° Cancer 33' at midday ℞
power, generational
Pluto in Cancer dates Martin to an era rather than describing one person. Those born in it live through deep transformation of family, home and nationhood. What an individual may carry is intensity around belonging and who counts as family.
Aspects in Martin Cooper’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 trine Neptune
about 0.8° at midday
Optimism and imagination tend to flow together for Martin Cooper, and what comes of it is an inspired, generous vision of what is possible. Hope and creativity tend to serve them well under this trine, especially when both are allowed to guide a project and neither is second-guessed.
Sun square Uranus
about 1.2° at midday
When the Sun is square Uranus, Martin's identity keeps bumping against a need to break from convention, which can look like sudden changes of direction that surprise the people nearby. The skill is choosing those disruptions rather than letting restlessness choose them.
Mars sextile Jupiter
about 3.0° at midday
There is confident, well-aimed energy in this sextile, and not much wasted effort, since Martin's drive and optimism pull together. Taking the initiative suits Martin, above all when they commit to one goal and do not scatter their energy across several.
Sun trine Neptune
about 3.5° at midday
Martin's identity and imagination flow together easily, giving them an intuitive, artistic quality that feels natural rather than performed. With the Sun trine Neptune, compassion comes without much effort, and other people often sense it before a word has been said.
Mars sextile Neptune
about 3.8° at midday
In Martin's chart, drive and imagination help each other along gently, so inspired action is possible before everything has been mapped out. The motivation is soft but workable, and it keeps a creative or compassionate project moving without forcing it.
Sun trine Jupiter
about 4.3° at midday
With the Sun trine Jupiter, Martin's sense of self and instinct for growth support each other, which gives them a warm, expansive confidence. They are likely to be quick to see an opening and to make the most of it without forcing anything.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
