Mark Shuttleworth’s zodiac sign and chart, in brief
18 September 1973 was a Tuesday: the day Mark Shuttleworth was born in Welkom, South Africa. Their zodiac sign is Virgo, with the Moon in Gemini. Mark turns 53 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 ten planets, five are in air signs, two in earth, two in water and one in fire. By modality the count is four cardinal, three fixed and three mutable. Three planets stand together in Libra: Mercury, Uranus and Pluto. Closest of the aspects is the square between Saturn and Pluto, 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 was retrograde. Over the course of the day the Moon went from waning gibbous to last quarter.
StarMap's dataset holds 20 other people born on 18 September, among them Anna Netrebko, Ronaldo and Greta Garbo. James Marsden was born on the very same day.

Mark Shuttleworth’s Sun, Moon and rising sign
Sun sign
Virgo
about 25° Virgo at midday
A Virgo Sun refines. Mark Shuttleworth 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
Gemini
in this sign all day; the degree depends on the birth time
The Moon in Gemini processes feeling by naming it. For Mark, 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.
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 Welkom, South Africa, at each hour of the day.
Mark Shuttleworth’s rising sign, by birth time
StarMap has not verified a birth time for Mark 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 18 September 1973, computed for Welkom, South Africa.

Mark Shuttleworth’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Mark Shuttleworth’s private life.
A Virgo Sun finds purpose in being useful and doing a job properly, and Mark Shuttleworth'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.
The Moon in Gemini runs its daily habits on conversation and mental stimulation, and Mark 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.
Mercury in Libra thinks by weighing both sides, and Mark tends to communicate diplomatically, often finding the version of an idea that will land well with whoever is listening. Settling on an opinion can take so long that the moment for it passes. They may change their mind in the middle of a conversation because the other point had merit.
Venus in Scorpio loves intensely and privately, and Mark is likely to value depth and total honesty over ease. Testing loyalty can create the very distance this placement fears most. There is an all-or-nothing quality to how this Venus commits, with little interest in anything in between.
Mars in Taurus acts deliberately and sticks with a course once chosen, and its anger builds slowly but takes a long time to cool once it arrives. At times Mark may dig in out of stubbornness rather than conviction. It takes real provocation to make this Mars snap, and the rattled feeling tends to last a while afterwards.
Jupiter in Aquarius
2° Aquarius 27' at midday ℞
growth and excess
Jupiter in Aquarius grows through community, ideas and causes bigger than one life. Mark may put so much trust in a theory or a group that its practical flaws are overlooked. Optimism about the future can make them a natural organiser of other people's efforts.
Emotional security is where Mark's Saturn in Cancer builds discipline; it is a placement often associated with learning early to be the steady one. Asking for care tends to be difficult with this Saturn, even when care is clearly needed. Over time, people with this placement often become the dependable anchor for others, including some who never quite return the favour.
Uranus in Libra
21° Libra 40' at midday
freedom, generational
Mark holds Uranus in Libra in common with many people born in the same stretch of years. Together that generation reshapes ideas of partnership, fairness and how relationships are arranged. Its personal side is a readiness to question traditional roles more openly than earlier generations felt able to.
Neptune in Sagittarius
4° Sagittarius 57' at midday
imagination, generational
Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Mark in it may be a hopeful conviction that the right philosophy will resolve a practical problem.
Pluto in Libra
3° Libra 56' at midday
power, generational
Pluto in Libra is the signature of the generation Mark belongs to, because Pluto moves so slowly. That generation transforms ideas of partnership, fairness and what people owe one another. Personally it can be an intense need for relationships to be fundamentally fair.
Aspects in Mark Shuttleworth’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.
Saturn square Pluto
about 0.1° at midday
Saturn square Pluto sets the need for control against the instinct for transformation, and Mark Shuttleworth may grip a structure most tightly at the very moment it needs to change. Each old form that is let go leaves a strength behind that is more real than the grip was.
Jupiter trine Pluto
about 1.5° at midday
In this trine, Mark's optimism and capacity for transformation feed each other, and the combination can give them the power to turn a big vision into lasting change. The growth it brings tends to be deep as well as broad, which is why the bigger changes usually stick.
Venus trine Saturn
about 1.9° at midday
A steady, dependable way of loving, one that people trust, is what this trine gives Mark, since affection and commitment hold each other up. Relationships built on it tend to last, often well past the point where less committed people would have moved on.
Jupiter sextile Neptune
about 2.5° at midday
Inspired ideas are within Mark's reach without any loss of footing, since possibility and imagination are gently linked by this sextile. The optimism is soft and workable, useful for keeping a project hopeful without letting it drift far from what is real.
Mercury sextile Neptune
about 3.0° at midday
Mark's thinking and imagination cooperate gently, so creative and intuitive ideas are within easy reach. The inventiveness is soft and pleasant rather than analytical, useful for easing a difficult conversation without losing the point of it.
Venus opposition Mars
about 3.4° at midday
Venus opposite Mars sets what Mark wants for themselves against what keeps a relationship harmonious, most of all around desire and assertiveness. Naming a want plainly, instead of swallowing it or forcing it, tends to serve both sides.
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.

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?
