The Square is an arc of separation or angular distance between the planets of  90º

• It involves planets in inharmonious elements and thus calls forth significant effort in order to integrate  divergent energies.
• It represents a ‘tense or challenging interaction”
• Any close square involving one of the personal planets represents a major life challenge.
• This aspect shows where energy must be released, usually through action of a definite sort, in order that a new structure may be built.
• The friction produced in a  90º aspect exerts relentless developmental pressure on each of the planets.
• The square can have the nature of Saturn– you have to deal with it.
• Common orb: 8 degrees on either side of exactitude.
