Aries Sun, Taurus Moon: one sign apart.
The short answerAries Sun with Taurus Moon means you are aiming to be first, and to find out what you are capable of by doing it rather than planning it, while needing to know nothing is about to change, and to be physically comfortable. The two signs are next door to each other, one sign apart, so the aim and the need pull against each other. It also means you were born somewhere in the new moon part of the cycle.
Aries 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 Aries that is to be first, and to find out what you are capable of by doing it rather than planning it.
What Aries quietly takes pride in is nerve. At its best this placement becomes somebody who starts things other people were still discussing. Aries is Fire and Cardinal, ruled by Mars, and the recognised weak spot is that it starts more than it finishes.
Taurus 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 Taurus you need to know nothing is about to change, and to be physically comfortable.
What settles you: food, routine, familiar places, being left alone with something to do with your hands. And the giveaway, the thing people close to you would recognise: goes quiet and immovable rather than loud. Taurus is Earth and Fixed, ruled by Venus.
What happens when you put the two together
Aries and Taurus are next door to each other, which is one sign apart. Adjacent signs share a boundary and little else. The aim and the need are slightly out of step in a way that is more nagging than dramatic, and most people with it have never put it into words.
Fire and Earth are different elements, which is the part that actually produces the mismatch people notice: you are aiming with one kind of energy and recovering with another.

The practical version
Because the two disagree, you will recognise this: the thing you are working toward keeps costing you the thing you need. To be first, and to find out what you are capable of by doing it rather than planning it does not sit comfortably with needing to know nothing is about to change, and to be physically comfortable, and most people with this combination have arranged their life around the tension without ever naming it.
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. Taurus is 1 sign ahead of Aries, 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.
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.
You aim to be first, and to find out what you are capable of by doing it rather than planning it while needing to know nothing is about to change, and to be physically comfortable. The two signs are next door to each other, so those pull against each other.
Is Aries Sun Taurus Moon a good combination?
It is a demanding one, and that is not the same as bad. The friction is what forces people with this combination to examine themselves, which most comfortable combinations never have to.
Do I need my birth time for this?
Not for the Sun. For the Moon, often yes: the Moon changes sign every two and a half days, so anybody born on a day it moved needs a time to be sure.
What lunar phase was I born under?
Taurus is 1 ahead of Aries, which puts you in the new moon band. The exact phase needs degrees rather than signs.
