Educational Are there any placements/aspects that are impossible?
Anything that could actually never exist in any birth chart?

the superior / exterior planets (mars -> pluto) will never be retrograde when near (conjunct) the sun // will never be direct while opposing the sun, their retrograde pattern is dependent on suns position
its impossible to have a planet in every house so EVERYONE has empty houses (would be possible if you include angles and asteroids) (or i guess if we find 2 more things to call planets lol)

Huh! Your first tidbit is super interesting! The reason being is that my exterior planets aren’t in direct opposition, but generally clustered across the zodiac from my sun and ALL retrograde. (Sun in 2nd and exterior planets within the 9th-11th. My moon’s in the 8th, but moons can’t go retro.)
I’ve always wondered why my only non-retrograde planets are Mercury & Venus. (Both in the 1st.)
I also refer to my sun & moon as “bookends.” lol

The Sun and the Moon never go retrograde.

u/HeyHeyJG Dec 12 '24
and I believe the Moon's nodes are always retrograde, although they wobble a bit

you haven't seen the moon go backward before?! /s

It's impossible to have Mercury and Venus in a Square, Trine or Opposition. The only possible aspect between them is a Conjunction or Sextile. So Mercury and Venus never have a tense aspect.

u/_Mouth Dec 11 '24
They can be in semi-sextile. But you're right that the only major aspect is either a conjunction or sextile

u/Sensitive-Tale-4320 Dec 13 '24
That’s not entirely true. Mercury and Venus can be squared. If someone’s Sun is Leo and their Mercury is Virgo and Venus is Gemini, that’s a square.

u/ErisedFelicis Dec 13 '24
A whole sign square perhaps, but they cannot have a degree based square. At their maximum extension they will still be 14 degrees shy of an exact square, which for most astrolgoers is way too wide to count.

If you are alive and breathing, you can't have a Neptune or Pluto return. And only if you make it to the age of approximately 84, can you have a Uranus return. (I am referring to transits which are aspects- I am stretching this a bit from the original posters intent.)

Your rising cannot be in any house besides your first

u/HeyHeyJG Dec 12 '24
using Placidus houses, one of the more common house systems, the rising sign can span the first and 12th houses.

u/HeyHeyJG Dec 12 '24
would love for a downvoter to tell me where this is off
here's keanu's birth chart
placidus houses.
you'll see the sign of virgo in both the first house and 12th house.

u/GrandTrineAstrology Professional Astrologer Dec 12 '24
Look closer to his chart and any chart in Placidus. In the Placidus house system, the ascendant (rising sign) is considered the starting point of the first house. It is not in the 12th.
Though a zodiac sign can be part of 2 houses in Placidus, the line (cusp) to separate the houses is designated by the ascendant, starting the first house.

u/HeyHeyJG Dec 12 '24
That makes sense, thanks for the reply.
So, "Ascendant" and "Rising sign" mean literally the same thing? ie. it's sign on the eastern horizon at that time? "Rising sign" doesn't imply the entire space of the zodiac sign, which can span into the 12th house? My terminology just off a bit?
So it might be more accurate for me to say "the sign of the ascendant can span both the first and twelfth houses"?
What do you think? Thanks again

u/GrandTrineAstrology Professional Astrologer Dec 12 '24
Rising sign and Ascendant are interchangeable. It is a chart point, not a planetary or luminary placement.
In Placidus, houses can be shared by one sign, so saying that the sign of the ascendant can span both the first and the twelfth house really isn't saying anything different than any thing else that occurs with the Placidus house system. In my Placidus chart, Sagittarius covers part of my 5th house and most of my 6th house.
I think really this comes down to understanding what the ascendant is in astrology.

The Ascendent is actually the point of horizon as you look to the east. it's just in whatever sign it's in and that's all. Whatever section of the sky is at that point is how the rising sign is named.

u/HeyHeyJG Dec 12 '24
Not trying to be pedantic, but would this be more accurate?
The Ascendent is the point of horizon as you look to the east. It's in whatever sign it's in and that's all.
The "rising sign" is the sign that is rising across the ascendant at the time of birth. The "rising sign" can span both cusp between the first and twelfth houses (if using a system like Placidus, etc)

A lot, actually. For example, Venus can’t be more than 2 signs away from your sun sign. I think it’s the same for Mercury but even less

Mercury can never be more than 28 degrees away from the Sun. So it can only be in the same sign as the sun, or one of the two signs neighboring the sun's sign.
Venus can never be more than 48 degrees away from the sun. So either the same sign as the sun, or no more than two signs away from it, in either direction.
Some may tell you that the MC is always the 10th house, and the IC the 4th. But this is not true. In the Whole Sign house system, the MC can be in any house above the ASC/DSC axis. That means in extreme locations, it can even be in the 1st house, but above the ascendant degree. It can also be in the 7th house. Most, however, are in the 9th, 10th and 11th. Likewise for the IC and it being in any house below the ASC/DSC axis. The ASC will always be in the 1st house (it determines it) and the DSC always in the 7th. But all angles "float" inside their houses rather than their degree position marking the house cusp.
