Portia de Rossi’s zodiac sign and chart, in brief

31 January 1973 was a Wednesday: the day Portia de Rossi was born in Horsham, Victoria, Australia. That makes Portia an Aquarius. The Moon left Sagittarius for Capricorn at about 05:55 local time, which leaves the Moon sign open without a birth time. Portia turns 53 in 2026. StarMap has no verified birth time for Portia, so the chart is cast for midday and leaves the houses out.

Air carries the most weight: five of the nine planets whose sign does not depend on the birth time, against fire two, earth two and water none. By modality the count is four cardinal, three mutable and two fixed. The tightest aspect is Venus conjunction Jupiter, about 0.7° 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: Saturn, Uranus and Pluto. The Moon was a waning crescent.

StarMap's dataset holds 19 other people born on 31 January, among them Justin Timberlake, Kenzaburō Ōe and Norman Mailer. Wikidata links Portia with one person in the dataset: Ellen DeGeneres (married in 2008).

Portia de Rossi’s Sun, Moon and rising sign

Sun sign

Aquarius

about 11° Aquarius at midday

An Aquarius Sun sees differently. Ideas ahead of their time, a wide circle of friends and a stubborn streak of independence are the marks of this placement in Portia de Rossi's chart. The growth is letting people close without feeling caged.

All Aquarius Suns

Moon sign

Sagittarius or Capricorn

Sagittarius until about 05:55, then Capricorn (local time). Which one depends on a birth time StarMap does not have.

Born before about 05:55: Moon in Sagittarius

A Sagittarius Moon feels best in motion. Open roads, new ideas and honest laughter probably lift Portia, and being fenced in by other people's moods tends to weigh them down. This Moon needs room, and someone who thinks that is fine.

Born after about 05:55: Moon in Capricorn

A Capricorn Moon feels responsibly. With it, Portia 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.

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 Horsham, Victoria, Australia, at each hour of the day.

Portia de Rossi’s rising sign, by birth time

StarMap has not verified a birth time for Portia 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 31 January 1973, computed for Horsham, Victoria, Australia.

Portia de Rossi’s planets, sign by sign

Each planet by sign: what the placement is traditionally taken to mean, not a claim about Portia de Rossi’s private life.

  1. Sun in Aquarius

    11° Aquarius 01' at midday

    purpose and vitality

    Portia de Rossi's purpose, with the Sun in Aquarius, probably lies in being useful to a group or an idea bigger than themselves, with a vitality that rises around causes and communities. The tension can be detaching from their own needs while championing everyone else's. It is the placement of the reliable one at meetings who is the hardest person to reach one to one.

  2. Moon in Sagittarius or Capricorn

    Sagittarius until about 05:55, then Capricorn

    needs and habits

    Born before about 05:55: Moon in Sagittarius

    The Moon in Sagittarius needs room to move and a bit of novelty in its routine to feel right. A schedule with no give in it can make Portia edgy faster than most people expect. With this Moon, the next trip tends to be planned before the current one has finished.

    Born after about 05:55: Moon in Capricorn

    With the Moon in Capricorn, Portia'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.

  3. Mercury in Aquarius

    12° Aquarius 34' at midday

    mind and voice

    In Portia's chart, Mercury in Aquarius describes thinking that is original and a step removed from convention, and communication that works best through ideas rather than small talk. The stubborn streak is holding a position out of principle after the evidence has moved on. In a group, this is the person who asks the question nobody else thought to ask.

  4. Venus in Capricorn

    24° Capricorn 04' at midday

    love and values

    For Portia, Venus in Capricorn means loving in a measured, committed way and valuing stability, ambition and someone to build a life with. The trap is treating a relationship like a project to manage rather than let unfold. With this Venus, love comes out more easily as providing and planning than as words said out loud.

  5. Mars in Sagittarius

    21° Sagittarius 31' at midday

    drive and anger

    Mars in Sagittarius acts boldly and wants room to move while doing it, and its anger flares fast over anything that feels like a limit on freedom. Portia may speak bluntly in the heat of the moment and smooth it over later. Given the choice, this placement walks away from a fight rather than staying to work it out.

  6. Jupiter in Capricorn

    24° Capricorn 48' at midday

    growth and excess

    Jupiter in Capricorn grows through long-term discipline, and Portia would probably rather build slowly and properly than quickly. The overreach is taking on more responsibility than any one person should reasonably carry. The authority this Jupiter brings is slow and hard-won, the kind people tend to trust more the longer they know someone.

  7. Saturn in Gemini

    13° Gemini 48' at midday ℞

    discipline and doubt

    Saturn in Gemini builds discipline around clear expression, and it often begins with doubt about whether an idea is good enough to say out loud. For Portia that would mean overpreparing before speaking or writing anything. Once the self-consciousness eases, the result can be someone unusually precise and credible with words.

  8. Uranus in Libra

    23° Libra 03' at midday ℞

    freedom, generational

    Portia 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.

  9. Neptune in Sagittarius

    7° Sagittarius 02' at midday

    imagination, generational

    Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Portia in it may be a hopeful conviction that the right philosophy will resolve a practical problem.

  10. Pluto in Libra

    4° Libra 15' at midday ℞

    power, generational

    Pluto in Libra is the signature of the generation Portia 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 Portia de Rossi’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.

  1. Venus conjunction Jupiter

    about 0.7° at midday

    Venus conjunct Jupiter tends to make Portia de Rossi's capacity for love and pleasure generous and expansive, and it usually comes with a warm enjoyment of life. The result is naturally good company; the thing to watch is the point where generosity has quietly become excess.

  2. Venus square Uranus

    about 1.0° at midday

    In Portia'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.

  3. Mercury trine Saturn

    about 1.2° at midday

    Portia's thinking has discipline behind it, which gives them a clear, methodical way of working through ideas. With Mercury trine Saturn, conclusions can be trusted because they have usually been tested already, often more thoroughly than anyone nearby realises.

  4. Mars sextile Uranus

    about 1.5° at midday

    Bold, original action comes to Portia without much friction, because drive and independence are on good terms in this sextile. It is useful initiative with little drama attached, the sort that tries something new without making a big production of it.

  5. Sun conjunction Mercury

    about 1.6° at midday

    With the Sun conjunct Mercury, Portia's sense of self and way of thinking are fused, so an opinion can feel like a statement of who they are. They are likely to speak their mind readily, and telling a passing thought apart from their identity is a practice worth keeping up.

  6. Jupiter square Uranus

    about 1.8° at midday

    An appetite for growth can turn erratic under Jupiter square Uranus, with sudden changes of direction that leave earlier plans unfinished. The instinct for change this square gives Portia is a good one, and it does most when channelled into fewer, more deliberate moves that get to see the finish line.

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.

  • Sun trine Saturnabout 2.8°
  • Neptune sextile Plutoabout 2.8°
  • Sun sextile Neptuneabout 4.0°
  • Saturn opposition Neptuneabout 6.8°
  • Sun trine Plutoabout 6.8°

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?
