Venus and Mars in one birth chart: the five major aspectsSchematic natal wheel. Venus is held at the top. Five marks show where Mars would sit for each major aspect: conjunction at 0 degrees, sextile at 60, square at 90, trine at 120 and opposition at 180. The same angles count in either direction around the wheel.60°90°120°180°Venus

Venus-Mars aspects in a birth chart describe the angle between Venus and Mars at the moment a person was born. This is a natal reading: both positions come from one chart and one instant, and the aspect describes something within one person. In modern Western astrology Venus stands for value and pleasure, what a person finds attractive, beautiful or worth keeping, and Mars stands for drive, how they assert themselves, pursue what they want and handle anger. The aspect describes how wanting and going after it meet.

This pair behaves differently from the Moon pairs. Venus moves about a degree a day and Mars rather less, so the angle between them changes by around half a degree a day. In the site’s eight-year sample a Venus-Mars aspect stayed in range for between 9 and 54 days in a row, so many people born in the same few weeks share it. The birth hour hardly matters here, and each chart’s signs, houses and other aspects do the work of making a shared aspect personal.

Venus and Mars are often read together when people talk about attraction. The sections below describe one person’s own way of combining value and effort, in work and play as much as in affection.

Venus conjunct Mars in a birth chart

A Venus-Mars conjunction places the two planets close together on the wheel, usually in the same sign. It is the longest-lasting of the five angles for this pair: in the site’s sample a conjunction stayed within its 8 degree orb for between four and eight weeks, so a good number of people share it.

The traditional reading joins value and drive in one place. What a person finds attractive and how they go after it tend to be the same impulse; liking something and moving toward it happen at once. Many astrologers describe this as a lively, warm placement.

Someone loves a particular craft and works at it with real intensity; the pleasure and the effort feel like one thing. A useful question is what happens when the two separate: when a task must be done that the person does not enjoy, or when something they enjoy asks for no effort at all.

The tradition also links this aspect to directness about what one wants. Notice whether wanting tends to turn into action before there has been time to consider it. The sign and house matter a great deal, since both planets share them: a conjunction in Taurus reads differently from one in Aries or Scorpio. Because this aspect holds for weeks, its exact orb is what sets one chart apart from another born nearby.

Venus sextile Mars in a birth chart

A sextile puts Venus and Mars about 60 degrees apart, two signs from each other. The signs usually cooperate, fire with air or earth with water, while staying distinct. In the site’s sample a Venus-Mars sextile lasted from about a week and a half to six weeks.

The traditional reading calls the sextile an opportunity. Value and drive are separate enough to stay distinct and similar enough to help each other. Effort may come more easily when it serves something the person cares about, and what they care about tends to give them reasons to act. An opportunity takes a little initiative to use.

Picture someone who enjoys cooking for friends. The effort of shopping and preparing is easier because of the pleasure at the end, and the pleasure is sharper because effort went into it. The reflection is where such small joinings already happen, and whether the person would like more of them.

The sextile is the smallest of the five major angles, and for this pair the site uses the standard 4 degree orb. A chart that shows none may have Venus and Mars just outside it, and the planet table shows how close they came. A mild aspect is also easy to miss, so ask where enjoyment and effort already work together.

Venus square Mars in a birth chart

A square places Venus and Mars about 90 degrees apart, three signs from each other. The signs usually share a mode: cardinal, fixed or mutable. They differ in element, so they act in a similar manner for different reasons. In the site’s sample a Venus-Mars square held for between about two and five weeks, so it too is shared by many people born around the same time.

The traditional reading calls the square a tension. What a person values and how they go after it do not always agree. They may want harmony and find themselves pushing, or want to push and find themselves holding back to keep things pleasant. The tradition describes this as a recurring negotiation between ease and effort, not a defect.

Someone values calm, considerate exchanges and also has a quick temper when something feels unfair. The square suggests that a practical arrangement helps more than a resolution to be one way: a pause before replying, a habit of saying plainly what is wanted, a place for energy that is not a conversation.

Astrologers often describe Venus-Mars squares as a source of creative or competitive energy, since the friction has to go somewhere. The site counts a square within 7 degrees for this pair. Because the planets move slowly, the birth hour almost never changes it, but their signs and houses differ from chart to chart and say most about what a shared square is about.

Venus trine Mars in a birth chart

A trine places Venus and Mars about 120 degrees apart, four signs from each other and usually in the same element. The two planets share a temperament, fire with fire or water with water, so value and drive speak a similar language. In the site’s sample a Venus-Mars trine lasted from about nine days to nearly five weeks.

The traditional reading calls the trine harmonious. What a person enjoys and how they pursue it tend to agree, and acting on a preference may feel natural rather than forced. The tradition’s usual caution applies: ease is a condition, not an accomplishment, and it can be left unused.

Consider someone who plays a sport for the pleasure of it and trains without needing to push themselves; effort and enjoyment arrive together. A useful reflection is what happens when a goal needs effort without pleasure, or pleasure that asks for patience.

Next to the square, which keeps asking for adjustment, the trine rarely asks for anything, so it is easy to overlook. The site counts a trine within 7 degrees for this pair. The birth-time panel below shows a Venus-Mars trine near that limit which holds for only part of its date. That is the one situation in which the birth time matters for this pair: an aspect close to the edge of its orb.

Venus opposite Mars in a birth chart

An opposition places Venus and Mars about 180 degrees apart, on opposite sides of the wheel. Because Venus stays near the Sun, this puts Mars far from the Sun too, often near the time Mars is closest to the Earth and brightest in the night sky. It is the least frequent angle for this pair: the site’s eight-year sample has four opposition spells, each lasting ten days to two weeks.

The traditional reading treats the opposition as awareness through contrast. Value and drive face each other, so a person may come to know what they want by noticing how it differs from how they act. That can feel like being pulled between harmony and assertion, or like a clear sense of when to yield and when to press.

Someone is accommodating in most things and then, at a certain point, firmly not. The two may alternate rather than blend. The opposition invites balance rather than a final choice. A useful reflection is whether the switch between the two feels chosen or abrupt, and what tends to set it off.

Astrologers often say a person first recognizes one side of an opposition in someone close to them. That is a suggestion from the tradition, and it casts no one in a role. The site counts an opposition within 8 degrees for this pair, the standard limit. As with every Venus-Mars angle, the planets’ signs and houses, and any close aspects to other planets, say more about a particular opposition than the angle alone.

Reading Venus-Mars in your own chart

Start with what the calculator shows: the angle and the exact orb. For this pair the birth time is a minor question unless the orb is close to its limit. The more useful question is what is particular to this chart.

The particular part comes from signs, houses and other aspects. Venus’s sign and house describe what a person values and where; Mars’s describe how and where they act. A close aspect from the Moon or the Sun to either planet makes the theme more personal.

These readings describe a pattern in how one person combines enjoyment and effort, to reflect on rather than a verdict on anyone or a forecast of what happens. A useful reading leaves room for “not quite”, and for the person’s own better description.

How the calculator counts an aspect

The birth chart calculator places Venus and Mars on the zodiac wheel as seen from Earth at the moment of birth. It measures the gap between them the short way round, anywhere from 0° to 180°, and names the aspect whose angle is nearest. The aspect only counts if the gap is close enough to that angle. How far from exact it may be is called the orb. Neither planet is the Sun or the Moon, which astrologers give more room, so this pair uses the standard orbs.

How far from exact each aspect can be for Venus-Mars, in degrees
AspectExact angleOrb for this pairWith the Sun or Moon
conjunction0°8°10°
sextile60°4°5°
square90°7°8°
trine120°7°8°
opposition180°8°10°

When the gap is narrowing toward exact, the aspect is called applying; when it is widening, separating. The calculator says which. The choice of house system and the place of birth do not change these angles. Orbs are a matter of custom, and other astrologers and apps use different ones.

Positions run from 0° to 360° around the wheel, so the numbers can look far apart when the planets are close. Moon at 358° and Venus at 3° are only 5° apart, a conjunction. A gap of 9.5° counts as a conjunction for Moon and Venus, but as no aspect at all for Venus and Mars, because the Moon gets more room. These positions are made up to show the idea.

For each body by itself, read Venus and Mars. Each angle has its own guide in the table above.

What an unknown birth time changes

Without a birth time the calculator draws the chart for noon on the birth date, says so on the result, and leaves out the rising sign and the houses. For a pair like this one, what matters is how far the two bodies move in a day.

On 2001-02-04 the gap between Venus and Mars went from 126.82° at the start of the day to 127.12° at the end (midnight to midnight, Greenwich time). At noon the calculator shows a trine, 6.97° from exact. Checked once an hour from midnight to midnight, though, the trine is there in only 15 of the 25 checks. The sextile in the first example below, 0.49° from exact at noon, is there in 25 of 25.

Checked every day from 2001 through 2008, a Venus-Mars aspect lasted between 9 and 54 days in a row. An unknown hour matters only when the aspect sits close to the edge of its orb, as in the case above.

Two worked examples

These two moments were chosen to show the aspect; they are not anyone's birthday. The positions come from the same calculation the birth chart calculator uses, given in degrees around the zodiac wheel from 0° at the start of Aries. Real birth times are rarely known this precisely.

All five aspects happen for Venus-Mars. The calculator found each one within 1° of exact on these dates: 2002-05-09 (conjunction), 2002-01-18 (sextile), 2001-11-22 (square), 2001-01-15 (trine), 2001-07-19 (opposition).

Questions about Venus-Mars in a birth chart

What does a Venus-Mars aspect mean in a birth chart?

It describes how what a person values and enjoys (Venus) meets how they assert themselves and go after things (Mars). Astrologers read the angle as a style of meeting: close, easy or tense.

Does my birth time change my Venus-Mars aspect?

Rarely. Venus and Mars both move slowly, so the angle between them changes by about half a degree a day. A Venus-Mars aspect usually holds for days or weeks, and only one close to the edge of its orb can change within a birth day.

Why does Venus-Mars use smaller orbs than Sun-Moon?

The site widens orbs only when the Sun or the Moon is involved, following a common convention. Venus and Mars use the standard limits: 8 degrees for a conjunction or opposition, 7 for a square or trine and 4 for a sextile.

Is this the same as one person's Venus touching another person's Mars?

No. This page reads Venus and Mars inside one birth chart. A contact between one person's Venus and another person's Mars is a two-chart comparison, a separate context that the compatibility tool calculates.
