The Twelve Houses

The First House in Astrology: Self and first impressions

The first house governs your appearance, your approach, your first move. Its natural sign is Aries, but the sign on yours depends on your rising sign. Here is the full table, what a planet there does, and why an empty house is not a problem.

The first house: self and first impressions. Which sign sits on it in your chart depends on your rising sign.
The short answerThe first house governs your appearance, your approach, your first move. Its natural sign is Aries, so Aries's qualities describe the house's basic character, but in your own chart the sign on this house depends on your rising sign, not on Aries. It is an angular house, which means it is one of the four loudest places in a chart.

Houses are the part of astrology that needs a birth time, and the only part that does absolutely. Signs and planets can be worked out from a date. Houses cannot: they are built outward from the degree rising on the eastern horizon, which changes every four minutes. Without a birth time there are no houses at all, and a chart drawn without one will still show twelve of them, which is why so many people are reading houses that are not theirs.

What the first house actually covers

In plain terms: self and first impressions. More fully, your appearance, your approach, your first move.

Angular houses are the loudest in a chart. A planet here does its work in public and early, and it is the first thing anybody notices about the person. The first is angular, so anything you have here operates that way.

The first and the seventh are one axisHouses work in pairs across the chart. The first house of self and first impressions sits opposite the seventh house of partnership and marriage, and the two are a single subject seen from both ends. Anything genuinely stuck in one of them is usually being held in place by the other.

Which sign is on your first house

This is the part that makes the house yours, and it is decided entirely by your rising sign. Find your rising sign in the table below and read across.

The planet that rules that sign becomes the ruler of your first house, and where that planet sits elsewhere in the chart is often more informative than anything inside the house itself. A first house ruler in the tenth, for example, connects self and first impressions to your public life.

A planet in the first house

Most houses in most charts are empty, and an empty house is not a missing part of a life. There are ten planets and twelve houses, so at least two are always empty and usually more. What a planet in a house does is give that department extra weight and a particular flavour.

What each planet tends to do in the first house
PlanetGovernsIn the 1st
Sunidentity and purposeVisible, and comfortable being looked at
Moonfeelings, needs and homeReadable, with feelings showing before they are named
Mercurythinking, speaking and learningTalkative, and quick to be known as clever
Venuslove, beauty, money and worthAttractive in a way people mention
Marsdrive, anger and desireDirect, physical, sometimes abrasive
Jupitergrowth, luck and beliefLarger than life and generally lucky with first impressions
Saturnlimits, work and maturitySerious young, and more at ease after forty
An empty house is not an empty lifeThis is the single most common worry about houses and it is entirely unfounded. An empty first house does not mean self and first impressions will be absent or difficult. It means that department runs on the sign on its cusp and on wherever that sign's ruler happens to sit, rather than being coloured by a planet sitting in it. Plenty of people with a great deal of self and first impressions in their lives have nothing in this house.

Aries, the natural first house

Aries is called the natural ruler of the first house because the two describe the same territory: Aries is a fire sign in cardinal mode, known for being direct, competitive, quick to start, and the first house is where self and first impressions happens. That correspondence is where the house's reputation comes from.

It is worth being clear that this does not mean your first house is Aries. Only Aries rising charts have Aries on the first house and the natural order all the way round. For everybody else the houses are rotated. The natural association tells you what the house is about in general; the table above tells you how it works in your chart.

Whole sign or Placidus

Two systems are in common use and they will give you different house positions for the same chart. Whole sign makes each house exactly one sign, which is what the table above uses and what most traditional practice uses. Placidus divides the sky unevenly by time, which means houses vary in size and a sign can be spread across two of them or skipped entirely.

Most apps default to Placidus without saying so. Neither is wrong, the argument is genuinely unresolved, and the practical advice is to pick one, learn it properly, and notice when a chart reads better in the other.

Questions people ask

What does the 1st house mean in astrology?

It governs your appearance, your approach, your first move. Its natural sign is Aries and it is an angular house, which means it is one of the four most prominent houses in a chart.

What does an empty 1st house mean?

Nothing is wrong. There are ten planets and twelve houses, so empty houses are normal. The department is run by the sign on the house and by wherever that sign's ruler sits, rather than by a planet inside it.

Which sign rules my 1st house?

It depends on your rising sign, not on your Sun sign. Using whole sign houses, count 0 signs forward from your rising sign. The table above lists all twelve.

Do I need a birth time to know my houses?

Yes, and there is no way round it. Houses are built from the degree rising on the eastern horizon, which moves about one degree every four minutes. Without a birth time the houses in a chart are decoration.

What is the opposite of the 1st house?

The seventh house, which governs partnership and marriage. The two work as one axis and are usually read together.
