History and approach
In medieval astrology, certain aspects and planets were considered to be either favorable (benefic) or unfavorable (malefic). Modern usage places less emphasis on these fatalistic distinctions. The more modern approach to astrological aspects is exemplified by research on astrological harmonics. In 1619, Johannes Kepler advocates this in his book Harmonice Mundi. Thereafter, John Addey was a major proponent. However, even in modern times, aspects are considered to be either easy (60° Sextile or 120° Trine) or hard (90° Square or 180° Opposition). Depending on the involved planets, a Conjunction (0°, which is a discounting orb) may be in either category.
