Planets in Signs
Sun governs identity and purpose, and Capricorn is an earth sign in cardinal mode. Here is what the placement does, its shadow, and the real dates Sun is in Capricorn.

Sun spends about a month in each sign, so anybody born in the same window shares the sign with you. What makes it yours is the house it falls in and the aspects it makes to the rest of your chart. This page is about the sign. The other half needs your birth time.
Before the sign, the planet. Sun rules identity and purpose. The question it keeps asking is who am I becoming. Wherever Sun sits in a chart is the department that question gets answered in.
Capricorn is an earth sign, which describes what it cares about, and cardinal, which describes how it goes about things. Earth wants to see the thing before it believes in it. Cardinal signs start things.
Sun is neither dignified nor debilitated in Capricorn. It neither rules the sign, nor is exalted in it, nor is in detriment or fall. In traditional terms that is called peregrine, and it means the planet is working without any particular advantage or handicap: it simply takes the character of the sign it is in. Most placements in most charts are like this, which is worth saying because pages that describe every placement as either blessed or cursed are not describing astrology.
Who you are when nobody is managing you, run through Capricorn. In practice that tends to look like responsible, ambitious and dry humored, applied specifically to identity and purpose, rather than to everything you do.
Capricorn's keyword is "I build", and the version of that which belongs to Sun is narrower than the sign description you will have read elsewhere. Somebody with Sun in Capricorn and very little else in the sign is not a Capricorn person. They are a person who handles identity and purpose the way Capricorn does.
Recognition for being this particular way rather than a generally impressive way. Capricorn wants something that lasts, that can be pointed at, and that does not need explaining, and the Sun here wants that to be the thing people actually see. Being praised for a quality you do not have is worse than not being praised.
And what it finds hard: being seen as the sign rather than as yourself, and the slow suspicion that the version people like is a performance. Carries what is not hers to carry, and that is the habit this placement has to watch.
The Sun is in Capricorn for about a month every year, which is Capricorn season. If you were born in that window, this is your Sun sign.

This is the part most planet-in-sign pages leave out, and it is why two people with the same placement can recognise almost nothing of each other in it. Sun in Capricorn in the tenth house is a public thing. The same placement in the twelfth is nearly invisible, including to the person who has it.
Which house it lands in depends on your rising sign, which depends on your birth time. The rising sign pages set out the whole structure, and the table there shows which house Capricorn occupies for each of the twelve.
| Planet | Sun |
| Sign | Capricorn |
| Element and mode | Earth, Cardinal |
| Sign ruled by | Saturn |
| Essential dignity | None. Neither dignified nor debilitated here |
| Needs a birth time | Rarely for the sign, always for the house |
The same planet in the signs either side is the sharpest comparison available: Sun in Sagittarius and Sun in Aquarius. And the capricorn decans narrow a thirty-degree sign down to ten, which is three times more specific than the placement on its own.
Sun governs identity and purpose, so in Capricorn it handles that department in a Capricorn way: responsible, ambitious and dry humored.
It is neutral, or peregrine: Sun neither rules nor is exalted in Capricorn, and is neither in detriment nor fall. It simply takes on the character of the sign. Most placements are like this.
Not for the sign itself, which Sun holds for a month in each sign. You do need one for the house it sits in, and the house is half the meaning.
A version of yourself performed rather than lived, shaped by Capricorn's tendency to carries what is not hers to carry.
