Mercury Square Venus
Mercury square Venus is astronomically impossible — Mercury and Venus both stay close to the Sun. If you see this aspect in a chart, suspect a calculation error.
Aspect: 90° · Nature: tension
What this aspect is
Mercury and Venus orbit inside Earth's orbit, which means they never appear far from the Sun in our sky. Mercury's maximum elongation is ~28° from Sun; Venus's maximum is ~48°. Together they can never be more than ~76° apart. A 90° square is therefore astronomically impossible in a natal chart.
If a chart shows Mercury square Venus, the most likely explanations are: (1) a coordinate-system or calculation error in the chart software, (2) a mis-typed birth time or location producing wildly off positions, or (3) the chart is using a mid-point or a calculated/derived point rather than actual planetary positions. None of these reflect a real Mercury-Venus relationship.
Strengths and gifts
N/A — the aspect cannot occur naturally.

Astronomical impossibility. Listed for SEO completeness so people who search for this aspect find the honest answer rather than a fabricated interpretation.
FAQ
Is Mercury square Venus possible?
No — Mercury and Venus both stay close to the Sun (28° and 48° max). Maximum separation is ~76°, well short of the 90° square.
What does it mean if my chart shows Mercury square Venus?
It almost certainly means there's a calculation error somewhere — wrong birth time, wrong location, wrong coordinate system, or buggy software. Recalculate with a different tool to verify.
Why list this aspect at all?
For honest SEO. People search for it; the right answer is 'impossible, here's why' rather than a fabricated interpretation.
