Bruno Mars’s birth chart
Born 8 October 1985, in Honolulu, Hawaii. StarMap has no verified birth time yet.

Bruno Mars’s zodiac sign and chart, in brief
Bruno Mars was born on Tuesday, 8 October 1985, in Honolulu, Hawaii. That makes Bruno a Libra. The Moon left Cancer for Leo at about 01:35 local time, which leaves the Moon sign open without a birth time. Bruno turns 41 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, three are in earth signs, three in air, two in water and one in fire. Across cardinal, fixed and mutable signs the split is three, three and three. Closest of the aspects is the sextile between Sun and Uranus, about 0.7° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. No planet was retrograde. The Moon was a waning crescent.
StarMap's dataset holds 14 other people born on 8 October, among them Sigourney Weaver, Matt Damon and Bella Thorne.

Bruno Mars’s Sun, Moon and rising sign
Sun sign
Libra
about 15° Libra at midday
A Libra Sun balances. Fairness, beauty and the quality of relationships tend to shape Bruno Mars's decisions, and this is a placement that can see both sides of almost anything. The growth lies in choosing a side when it counts.
Moon sign
Cancer or Leo
Cancer until about 01:35, then Leo (local time). Which one depends on a birth time StarMap does not have.
Born before about 01:35: Moon in Cancer
The Moon is at home in Cancer. For Bruno 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 01:35: Moon in Leo
A Leo Moon feels with its whole heart and needs that to be noticed. Warm attention tends to fill Bruno 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 Honolulu, Hawaii, at each hour of the day.
Bruno Mars’s rising sign, by birth time
StarMap has not verified a birth time for Bruno 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 8 October 1985, computed for Honolulu, Hawaii.

Bruno Mars’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Bruno Mars’s private life.
With the Sun in Libra, Bruno Mars's vitality is likely to rise in good company, and purpose to feel real when they are creating balance or beauty with other people. The risk is losing their own direction while managing everyone else's. Deciding alone is probably harder for them than deciding with a second opinion in the room.

Cancer until about 01:35, then Leo
needs and habits
Born before about 01:35: Moon in Cancer
With the Moon in Cancer, Bruno'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 01:35: 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 Bruno faster than a hard day with an audience. The mood tends to lift visibly the moment someone compliments something small Bruno did.
Mercury in Libra thinks by weighing both sides, and Bruno 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.
With Venus in Virgo, Bruno 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.
Mars in Virgo acts carefully and precisely, preferring to get a task right over getting it done fast, and its anger usually comes from things being done sloppily. When upset, Bruno is more likely to criticise than to confront. A clipped tone often signals frustration well before anything is said directly.
Jupiter in Aquarius
7° Aquarius 10' at midday
growth and excess
Jupiter in Aquarius grows through community, ideas and causes bigger than one life. Bruno 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.
Saturn in Scorpio builds its discipline around trust and control, and for Bruno 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 Sagittarius
14° Sagittarius 52' at midday
freedom, generational
Uranus in Sagittarius is less about Bruno than about the years around their birth. People of that age transform belief and access to knowledge, often through unprecedented exposure to other cultures and ideas. The personal trace is a restlessness with any single worldview presented as the only one.
Neptune in Capricorn
1° Capricorn 02' at midday
imagination, generational
Neptune in Capricorn is shared by Bruno and about fourteen years of births. The imagination of the generation questions or idealises authority and ambition, often shaped by wide disillusionment with institutions. The personal version may be an uneasy relationship with conventional success.
Pluto in Scorpio
3° Scorpio 54' at midday
power, generational
Pluto is at home in Scorpio, and the generation born with it lives through profound upheavals in power, secrecy and shared taboos. Bruno's own share may be an unusually deep comfort with intensity that others would find overwhelming.
Aspects in Bruno Mars’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.
Sun sextile Uranus
about 0.7° at midday
There is room for Bruno Mars to be a little unconventional without losing much by it, since identity and originality get along well here. Other people tend to find this easy, unforced independence refreshing rather than alarming.
Venus conjunction Mars
about 2.3° at midday
With Venus conjunct Mars, affection and drive are closely linked, so, for Bruno, wanting something and going after it are likely to feel like one impulse. The aspect brings plenty of romantic and creative energy; its test is letting the wanting outlast the first chase.
Jupiter square Pluto
about 3.3° at midday
Ambition can turn into a struggle for control under this square, over outcomes that were never fully Bruno's to control. The considerable drive involved is better aimed at transformation than at domination, which tends to produce a result that lasts.
Mars square Uranus
about 3.4° at midday
This square can make drive turn abrupt, leading to sudden decisions or breaks that surprise Bruno as much as they surprise everyone nearby. A brief pause before the impulsive move keeps the courage and loses the recklessness.
Mercury sextile Neptune
about 4.0° at midday
Bruno'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 square Uranus
about 5.7° at midday
In Bruno's chart the desire for closeness and the need for freedom can work against each other, and this square is known for sudden shifts in an otherwise good relationship. The remedy is to build enough independence into the relationship that none has to be created by pulling away.
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?
