Mars Square Neptune: Fog Underfoot Just When You Want to Run

Mars and Neptune hold each other back. When you want to act, doubt, fantasy, or a sense of powerlessness trips you up. Once you learn to see the goal clearly, you become a person of real resilience. This page starts from what Mars governs (drive, desire, competition and conflict) and what Neptune governs (ideals, imagination and dissolving boundaries), then looks at how the square makes the two interact, how it tends to show up in everyday life, its strengths and blind spots, and some advice for it.

The core meaning of Mars Square Neptune

Mars wants you to make a definite move, while Neptune blurs the outline of things. The square puts these two forces at cross-purposes. You have something you want to do, and before you start, a crowd of thoughts shows up. You worry that you are not good enough, or you imagine a result so perfect that nothing you could do now would measure up. At other times it runs the opposite way: a beautiful vision draws you in, you commit fully without looking closely, and only later find that things are not what you pictured.

The friction of this aspect is internal, and others may not see it. Unlike the opposition, which often places the problem on other people, those with the square mostly wear themselves down: wanting to do something and putting it off, feeling angry and unable to say so. When you are young this is discouraging, and you may conclude that your will is weak. With experience, you gradually work out a method for taking one step forward even when you are unsure. That ability is earned through wear, and it is especially dependable for that reason.

How it feels inside

You are unusually sensitive to the question “Am I really up to this?” Something you prepared for a long time can leave you feeling drained right when it is time to begin, and a careless criticism from someone can grow in your mind for days. You may also spend a period living on fantasy, picturing yourself suddenly succeeding one day while never actually getting started. These feelings are real, but they mostly show up before you begin. Once you are truly doing the thing, it is usually not as hard as you imagined.

In love and relationships

In love you tend to circle between giving and feeling wronged. You give ground for your partner and push your own needs down, and when you can no longer hold out you suddenly go cold or vanish, leaving them baffled. You may also be drawn to people who blow hot and cold and are hard to read, mistaking their vagueness for depth. Try voicing your displeasure while you are still calm inside, and watch what the other person actually does instead of only listening to what they say.

At work and in getting things done

At work the most common troubles are procrastination and a wavering sense of direction. There is a lot you want to do, yet you go back and forth among several options, or you take on a task and only then discover you never got the terms clear. Be especially alert to verbal promises and fuzzy divisions of labor on the job, and ask to have them put in writing. On the other hand, you can do very well in fields that need both imagination and endurance. Many artists and athletes who spend years honing a craft have this aspect in their charts.

Advice for Mars Square Neptune

Make “confirm first, commit second” a fixed routine. Before agreeing to any collaboration or invitation, ask the other party to put the terms in writing, and write down what you hope to get out of it as well. When something you want to do is stuck, ask yourself for just ten minutes, and allow yourself to stop when the time is up. What you need is to experience again and again that starting is not so scary after all. As those experiences add up, the fog slowly lifts.

What to keep in mind when reading this aspect

1. The tighter the orb, the more it matters. In our calculations, only 13.6% of all major aspects are within 1° of exact, and 41.2% are within 3°. If your Mars square Neptune is tight, the traits on this page will be more noticeable; if it is close to the 7° limit, they will be much fainter.

2. Applying and separating. An aspect is applying when the two planets are moving toward the exact angle and separating once they have passed it. Tradition holds that an applying aspect is still taking shape and acts more strongly. Our chart calculator marks which one you have.

3. Watch for out-of-sign aspects. Two planets in square are usually in signs of the same modality (both cardinal, both fixed or both mutable), but an aspect is measured by actual distance. In our calculations, 13% of squares do not match the usual sign relationship (one planet late in a sign, the other early in another). The nature of the aspect is still there; it just shows up in a less typical way.

4. Most people born on the same day share this aspect. Mars and Neptune move only a little in a day. The difference lies in which houses they fall in on your chart, and that depends on your birth time; see Planets in the Houses.

5. Then look at each planet’s own placement. The signs Mars and Neptune are in decide how each one expresses itself; see Planets in the Signs. If either planet has other aspects, read them together. For a complete reading, use the In-Depth Chart Reading.

A straight word: read an aspect as part of the whole chart

A single aspect describes the relationship between two planets. A chart has well over a dozen aspects on average, and they reinforce and offset one another. The same aspect in different signs and houses, with a tight orb or a loose one, can look very different in real life. Planetary positions are astronomical facts and can be calculated precisely; what an aspect means is astrological tradition, not scientific law. Everything on this site is for reference and entertainment only; for health, investment or legal matters, please consult a professional.

How can Mars square Neptune procrastination be improved?

This kind of delay mostly comes from imagining too perfect a result and feeling you are not ready yet.

Regular exercise brings the strength of Mars back into your body, and the feeling of actually getting things done grows with it.
