I have always been fascinated by unaspected planets. I am retired now, but I was an astrologer for many years and I saw a lot of charts. I would always ask as many questions as I could, when I had a client with a totally unaspected planet.
I don't count it as unaspected if there is an exact minor aspect, like a semi-sextile or semi-square or a quintile. To me, that just puts the focus strongly upon that one minor aspect and elevates it to a more important influence than it would be, normally.
So when I come across a totally unaspected planet, it is a very powerful thing, in my opinion.
I have seen it work in 2 very different ways, much like when someone has a total lack of an element in their chart. Often, one either 'lacks' that quality in daily life or they over compensate for it, and go overboard.
One example is the 2 clients I had with unaspected Mars. They both had 'Mars Issues' but in opposite ways.
I had a young client with her Mars in Aries in the 5th. It was unaspected, although she had the Sun in Aries too, but 15 degrees away.
She was an athlete and wanted to be on the Olympic fencing team. She was very talented. And kind of obsessed with the possibility.
Her mother had asked me to do a chart reading for her, and her mother was concerned because she wondered if her daughter was being realistic, as she let most everything else go and just focused on fencing. She was very ambitious and determined however and enthusiastically convinced me she was just working hard and knew what she was doing.
She didnt have much interest. in any thing else it seemed. I tried to discuss other aspects of her chart, like future careers, relationships, etc. But she really only seemed to care about the possibility or probability of her future in fencing.
I know she did move to NYC and was training at the Olympic training centre with the team, while in college, but I don't think she actually made the final team.
Around the same time, I did a session with a man, going through his Saturn Return. He had Saturn in Virgo, conjunct his Mercury/Sun in the 6th.
He was very concerned with his health, although the doctors had not found anything specific they could diagnose. But he had been feeling exhausted and weak, and couldn't gain weight. He had no appetite.
He had a lot of testing done. They were not sure what was going on physically.
He had Aries rising, with Mars as his chart ruler. Mars was in it's fall in Libra in his 7th. It was completely unaspected.
I asked him many questions about that Mars. Did he have relationships, partnerships...? No, and he said he had no interest in the idea even.
He said 'intimacy' annoyed him to just to think about the possibility. lol
The same with Mars type physical activities. He had no muscle strength. He was very thin and weak. And he said he liked that about himself because he was non violent and non-aggressive.
I know this is an extreme example of an unaspected Mars in it's fall, but it has always stuck with me.
One cool thing was that a few years later I saw him again. He was much happier and healthier, although still quite thin. But he was a bass player and singer in a popular punk/hipster band and looked very cool. I thought it was a nice expression of Mars in Libra in the 7th.
A truly unaspected planet works in various diverse ways but it is often a focal point in some way. It can be a pure kind of obsession or focus.
Or it can be a disconnected type of feeling that makes that planet's energy seem foreign or awkward in some way.
The Virgo musician with his unaspected Mars in Libra, felt disconnected from his masculine energy and used that to build a cool, hip persona of a tall slender Nerd
with big glasses that sang great lyrics in a smooth, smoky voice.
One of the most chilling charts I have ever seen was a chart another astrologer showed me at a Astro conference. One of his clients had come to him after giving birth too a stillborn child.
She was very grief stricken, looking for answers, and of course there aren't any that can truly help.
But he showed me the chart of the birth, and both the Sun and the Moon were totally unaspected.
I have never seen another chart with both of the lights unaspected. I don't know what it means but it gave me chills.
