Moon Signs

Cancer Sun Cancer Moon: A New Moon Birth

Cancer Sun aims to protect what matters and to be the one people come home to; Cancer Moon needs to feel safe and to be allowed to look after somebody. The two signs are the same sign, which is what decides whether those two agree, and it also tells you the lunar phase you were born under.

Cancer Sun, Cancer Moon: a new moon birth, with the Sun and Moon together.
The short answerCancer Sun with Cancer Moon means you are aiming to protect what matters and to be the one people come home to, while needing to feel safe and to be allowed to look after somebody. The two signs are the same sign, a new moon birth, with the Sun and Moon together, so the aim and the need work with each other. It also means you were born at or near a new moon.

Cancer Sun: what you are trying to become

The Sun is the aim. Not what you are like, which is a different question, but what you are consciously oriented toward and what you would be proud of being. With the Sun in Cancer that is to protect what matters and to be the one people come home to.

What Cancer quietly takes pride in is loyalty. At its best this placement becomes somebody who makes a place other people can be themselves in. Cancer is Water and Cardinal, ruled by the Moon, and the recognised weak spot is that it remembers every slight and files it.

Cancer Moon: what you need

The Moon is the private half, and it is usually the placement people recognise most sharply once it is described. It covers what you need in order to feel alright and what you do before you have thought about it. With the Moon in Cancer you need to feel safe and to be allowed to look after somebody.

What settles you: home, familiar people, and not being asked to explain. And the giveaway, the thing people close to you would recognise: withdraws into the shell and expects to be followed. Cancer is Water and Cardinal, ruled by the Moon.

What happens when you put the two together

Cancer and Cancer are the same sign, which is a new moon birth, with the Sun and Moon together. What you are aiming at and what you need are the same thing, which makes you unusually undivided and gives you nothing to balance against. People with this tend to be recognisably their sign in a way that almost nobody else is.

Both are Water signs, so even where the two differ they are made of the same material, which tends to make a person feel coherent from the inside even when they are not behaving consistently.

The practical version

Because the two agree, you are more consistent than most people: what you chase and what restores you point the same way, so you recover from effort rather than being drained by it. The cost is that nothing in you argues, and a person with no internal argument can go a long way in a direction nobody checked.

The useful move is not to pick a side. It is to notice which one you default to when you are tired, because that is almost always the Moon, and to notice what you have been postponing, because that is almost always the Sun.

The phase you were born under

There is a second thing these two placements tell you, and almost nobody mentions it. The distance from the Sun to the Moon, counted forwards, is the lunar phase you were born under. Cancer is the same sign as Cancer, which puts you in the new moon band.

That is a band rather than a verdict: the exact phase needs the degrees, not just the signs, so somebody at the edge of a sign could land either side of it. What a new moon birth is read as is here, along with the arithmetic to check your own properly.

What this page is missing

Your rising sign, which is what people meet first and which needs a birth time. On any given day, twelve different people share this Sun and Moon and have twelve different rising signs, and they do not come across remotely alike.

If you do not know your birth time, this covers how to find it, including which record to ask your state for. And the Big Three together are covered here.

Two placements out of about fortyThe Sun and Moon are the two biggest things in a chart and they are still two things. The rising sign, which needs a birth time, is what people meet first and is missing from everything on this page. So is every house, every aspect to anything else, and the whole of Mercury through Pluto. A Sun and Moon reading is a sketch, and a sketch that fits is not evidence of anything beyond the sketch being well drawn.
