Ascendant (ASC) — the sign rising on the eastern horizon at birth. It shapes outward manner. On the wheel, the horizontal axis is the Ascendant / Descendant axis. If birth time is unknown, this won't appear.

Midheaven (MC) — the highest point in the sky at birth. It points to vocation and public self. On the wheel, the vertical axis is the MC / IC axis. If birth time is unknown, this won't appear.

Chiron — a small body that moves between Saturn and Uranus, read as a sign of where lessons live.

North Node — not a body but a mathematical point of the Moon's orbit. It marks the direction of growth.

We sort them here by strength. Tight orbs come first — the closer the angle, the louder the aspect sings.

Classic includes the shapes established in modern astrology — T-Squares, Grand Trines, and more. Extended adds geometric configurations that carry meaning beyond traditional astrology.
