Boris Sidis birth chart is shown with zodiac signs and aspects. Because the birth time is unknown, Arcadia does not use houses, Rising sign, or angular dominants as the main basis of interpretation.
Boris Sidis's chart rests first on the stable factors: Sun in Libra and Moon in Aries. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mars trine Uranus (orb 1.6°) gives a central dynamic in this reading. The orb is very tight; this describes a stable character pattern more than a passing reaction.
In plain terms, this aspect gives ease acting fast, taking risks, and breaking inertia.
The birth time is not known with certainty, so the Rising sign and houses are less reliable. Signs and exact aspects give the safer reading base.

Signs Mercury in Scorpio · Venus in Libra · Mars in Scorpio
Aspects Jupiter square Saturn (orb 5.5°)
This section gives a concrete reading thread. It highlights the most visible signatures, then the tabs keep each placement separate instead of mixing everything together.
Important: Unknown birth time: the Rising sign, houses, and angular dominants are too time-sensitive to anchor the interpretation. The Moon remains useful, but its exact aspects can shift during the day: tight non-Moon aspects are more reliable when they exist.
Start here: a short reading that shows what hooks, what helps, what pushes back, and where it becomes concrete.
Sun in Libra · Moon in Aries
First hook: this is where the chart often becomes recognizable in real life. Sun in Libra: identity and direction move through relationship, balance, negotiation, and sense of form; Moon in Aries: emotional safety looks for initiative, speed, confrontation, and direct action. Because the birth time is missing, reliable aspects should carry the next step before houses or angles.
Dominants unavailable without reliable birth time
Angular dominants depend on birth time. Without a reliable hour, do not use them as primary evidence.
Harmonious link: Mars and Uranus
This is the easiest door into the chart: it shows what tends to cooperate naturally.
This pattern describes what comes more easily. Houses are not used here: unknown time. It connects Mars (action, anger, desire, and courage) and Uranus (change, freedom, rupture, and originality).
This is the clearest cooperation pattern in the chart: Mars trine Uranus (orb 1.6°). It shows where functions support each other, recover, or come naturally when used together. No wider group outranks this link, so read it as a strong but isolated signal.
Tension link: Mars and Pluto
This is the pressure line to read first: it shows where tension repeats in concrete situations.
This pattern shows where pressure builds fastest. Houses are not used here: unknown time. It connects Mars (action, anger, desire, and courage) and Pluto (power, crisis, intensity, and deep transformation).
This is the clearest friction pattern in the chart: Mars opposite Pluto (orb 4.3°). It shows where pressure, contradiction, or repeated effort concentrates. No wider group outranks this link, so read it as a strong but isolated signal.
Houses unavailable without reliable birth time
Houses describe domains of existence, but they depend on birth time. Without a reliable hour, signs and aspects should carry the reading.
Read the full chart-reading method · Detailed placements and aspects are below in the tabs.
Without a reliable birth time, the Sun, Moon, and exact aspects become the reliable base. The Rising sign, houses, and angular dominants need a reliable birth time.
The Moon can change signs during a day. Near a lunar sign change, the Moon sign remains a hypothesis.
Without a reliable hour, exact aspects and reliable repetitions can strongly nuance the starting reading.
Sun in Libra remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Libra style: relationship, balance, negotiation, and sense of form.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Libra style (relationship, balance, negotiation, and sense of form). Exact aspects and repeated patterns indicate whether this theme becomes central.
Sun conjunct Venus (orb 4.4°) brings the two planets out together. The orb is moderate; it stays secondary beside tighter signatures.
Here, both planets use the same Libra style (relationship, balance, negotiation, and sense of form). Sun in Libra brings identity, ego, father figure, visibility, and direction; Venus in Libra brings desire, taste, relationship, and attraction.
Concrete effect: this aspect brings identity, ego, father image, desire, taste, and attraction together: the person wants to be seen through what they love or embody.
Reading note: Common solar conjunction: Mercury and Venus always stay close to the Sun. It becomes genuinely meaningful when the orb is very tight, one factor is angular, or the same theme repeats elsewhere.
Sun opposite Neptune (orb 5.2°) puts the two planets face to face, with visible back-and-forth or tension. The orb is moderate; it stays secondary beside tighter signatures.
Concrete conflict: this aspect opposes ego or personal direction to image, dream, or public expectation.
Sun square Lilith (orb 5.3°) creates concrete friction between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Concrete friction: this aspect puts ego and personal image under pressure from Lilith's absolute ideal and refusal of compromise.
Moon in Aries remains a useful base without a birth time. The Moon sign is often usable, but near a Moon sign change it remains a hypothesis; the Moon describes personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm, with Aries style: initiative, speed, confrontation, and direct action.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Aries style (initiative, speed, confrontation, and direct action). Exact aspects and repeated patterns indicate whether this theme becomes central.
The Rising sign cannot be determined if the time is not known.
Mercury in Scorpio remains a reliable combination even without a birth time. Mercury describes intellect, language, thought, and technique, with Scorpio style: intensity, desire, crisis, secrecy, and invisible power.
Concretely, the person expresses thinking, speech, learning, technique, and mental strategy through the Scorpio style (intensity, desire, crisis, secrecy, and invisible power). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Mercury conjunct Mars (orb 4.7°). Aspect effect: makes thought move fast into speech, action, or argument.
Mercury conjunct Mars (orb 4.7°) brings the two planets out together. The orb is moderate; it stays secondary beside tighter signatures.
Here, both planets use the same Scorpio style (intensity, desire, crisis, secrecy, and invisible power). Mercury in Scorpio brings intellect, language, thought, and technique; Mars in Scorpio brings action, courage, competition, and effort.
Concrete effect: this aspect makes thought move fast into speech, action, or argument.

Concretely, the person expresses desire, taste, attraction, pleasure, and love style through the Libra style (relationship, balance, negotiation, and sense of form). Exact aspects and repeated patterns indicate whether this theme becomes central.
Same aspect, other side: the full reading is under the other planet, and it also applies to Venus.
Venus trine Jupiter (orb 4.8°) shows positive structural ease between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Concrete support: this aspect gives positive ease between charm, desire, generosity, and fulfillment: attraction can open horizons.
Mars in Scorpio remains a reliable combination even without a birth time. Mars describes action, courage, competition, and effort, with Scorpio style: intensity, desire, crisis, secrecy, and invisible power.

Concrete support: this aspect gives ease acting fast, taking risks, and breaking inertia.
Mars sextile Lilith (orb 2.1°) shows active cooperation between the two planets. The orb is tight enough to count in the main reading.
Here, Mars in Scorpio brings action, courage, competition, and effort with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Lilith in Capricorn brings pure ideal, absolute demand, fascination, and refusal of compromise with Capricorn style (structure, ambition, responsibility, and long construction).
