In astrology, a semi-square is an aspect that two planets make when they are 45° apart from each other. The semi-square is considered to be the 8th harmonic of the chart because it is one-eighth of the 360° circle that the zodiac resides in. The semi-square is considered to be a minor hard aspect because it is thought to cause friction in the native's life and prompt her to take some action to reduce that friction.
