There are two marked points in your chart that correspond to no body in the sky. Nothing is there: no rock, no light, no gas.
They are the lunar nodes, and despite being empty they are among the most used features of a reading.
What they are, without metaphors
The Moon does not orbit the Earth on the same plane the Earth orbits the Sun. There are about five degrees of tilt between the two paths.
Two tilted planes cross along a line, and that line touches the zodiac at two opposite points. That is the north node — where the Moon crosses upward — and the south node, where it crosses downward. They always face each other: know one and you know the other.
They move backwards, slowly: about 19 degrees a year. They take 18 and a half years to go all the way round and spend roughly a year and a half in each sign. Right now, for instance, the north node is in Aquarius — it entered on August 18, 2026 — and stays there until March 2028; the south node sits opposite, in Leo.
What they say in your chart
The usual reading is an axis between the known and the pending.
The south node marks what you already know how to do. The comfortable ground, the resource you fall back on when things get complicated. It works well, and precisely for that reason it is easy to stay there longer than necessary.
The north node marks the opposite: the ground where you feel clumsy and where, nonetheless, the missing part lives. It is rarely comfortable. It is almost always what people end up glad they did.
Like everything in the chart, they read with sign and house: the sign says in what manner, the house says where in life. The method is in the step-by-step reading.
Mean node and true node
Looking up your node, you may find two values that disagree. It is not an error: there are two ways to calculate it. The true node follows the real wobble of the lunar orbit; the mean node averages it out and moves evenly.
The difference between them rarely exceeds a degree and a half, so it almost never changes the sign. When it does, you are right on the border, and both are worth looking at.
Why eclipses happen there
This is the fact that ties everything together. An eclipse needs more than a new or full moon: the Moon must also be near one of the nodes, where the two planes touch.
That is why each season's eclipses always fall in the signs of the nodal axis of the moment, and why they shift signs every year and a half. The guide to lunations explains the other half of the mechanism.
A note on past lives
It is very common to read that the south node describes previous lifetimes. That is one school's interpretation, not a fact, and you do not have to believe it in order to use the nodes.
Without that addition, the axis stays perfectly readable: what you already master against what you still have to learn. That is enough.
The short version
- The nodes are the two crossings between the Sun's path and the Moon's: not bodies.
- They are always opposite and take 18 and a half years to circle.
- South node: what you already do well. North node: what is missing and costs.
- Eclipses only occur when a lunation falls near them.
- Mean and true node differ by little more than a degree.
