What this page measures
Horoscorpio reads the angle between Moon and Mercury from precomputed ephemeris and times the whole passage — when the pair enters a 2° orb of the exact 90°, when it is exact, and when it leaves. Measured from the Earth. Geocentric and heliocentric are separate observer frames and are never combined.
The instrument is free to use and requires no account. It shows every aspect currently in orb across all three observer modes, updating on the minute.
Questions
Is Moon square Mercury happening right now?
No. As measured at 2026-08-18 19:12 UTC, Moon and Mercury are 84.48° apart in the geocentric frame. That is 5.52° from an exact 90° square, outside the 2° orb, so the aspect is not live.
When is the next Moon square Mercury?
The next exact square falls on 2026-08-19 08:06 UTC, in 12h 54m. The pair is inside the 2° orb from 2026-08-19 03:24 UTC to 2026-08-19 12:48 UTC. This time is computed from the ephemeris, not taken from the live episode register.
What is a square in astrology?
A square is an angular relationship of 90° between two bodies as measured along the ecliptic. Horoscorpio treats it as live only while the measured separation sits strictly inside 2° of that angle. The angle is a measurement; Horoscorpio makes no claim about what it causes.
Is this measured from the Earth or the Sun?
Measured from the Earth. Geocentric and heliocentric are separate observer frames and are never combined.

Planetary geometry is measured from the live instrument. Horoscorpio states angles and times; it is not prophecy, and it is not medical, financial or legal advice. Times are UTC. Live in-orb state is read from the Horoscorpio episode register; the next exact time is computed from the ephemeris.
