quadrature
quadrature, in astronomy, arrangement of two celestial bodies at right angles to each other as viewed from a reference point. If the reference point is the earth and the sun is one of the bodies, a planet is in quadrature when its elongationelongation,
in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth.

The inferior planets (Mercury and Venus) never reach quadrature; the superior planets each have two points of quadrature in their orbits.quadrature (kwod -ră-cher) The position, or aspect, of a body in the Solar System when its elongation from the Sun, as measured from the Earth, is 90°, i.e. when the angle Sun–Earth–body is a right angle.quadrature[′kwä·drə·chər] (astronomy) The right-angle physical alignment of the sun, moon, and earth. (mathematics) The construction of a square whose area is equal to that of a given surface. The process of calculating a definite integral. (physics) State of being separated in phase by 90°, or one quarter-cycle. Also known as phase quadrature. AcronymsSeeQquadrature
