a situation in which three celestial bodies form a right-angled triangle, the observer being located at the right angle

When the Moon is in quadrature, it appears in the sky as a half-moon.

the process of making something square; squaring
the condition in which the phase angle between two alternating quantities is 90°
{n} the act of squaring, squareness, the quartering of the moon
a situation in which three celestial bodies form a right-angled triangle
A quadrate; a square
the process of constructing a square having the same area as a given plane figure, or of computing that area
the construction of a square having the same area as some other figure
An object is at quadrature when its hour angle is 6h from the Sun To a good approximation, for an object in the ecliptic plane, the angle between the Earth, the Sun, and the object is 90o Quadrature may also be used to refer to phases 0 25 and 0 75 of a binary star system
The relation between two waves of the same frequency but one-quarter of a cycle (90°) out of phase, as in TV color difference signals
The act of squaring; the finding of a square having the same area as some given curvilinear figure; as, the quadrature of a circle; the operation of finding an expression for the area of a figure bounded wholly or in part by a curved line, as by a curve, two ordinates, and the axis of abscissas
A point in the orbit of a superior planet where it appears at right angles to the Sun as seem from Earth
The position of one heavenly body in respect to another when distant from it 90°, or a quarter of a circle, as the moon when at an equal distance from the points of conjunction and opposition
The planet is either 90° east of the sun (eastern quadrature) which occurs a few months after opposition and is an evening object, or 90° west of the sun (western quadrature) which occurs a few months before opposition and is a morning object A superior planet always shows a more or less full phase, at quadrature the greatest departure from full phase occurs, and in the case of Mars a very appreciable gibbous phase can be seen For the other superior planets this effect is much smaller
The position of the phase cycle when the two principal tide producing bodies (moon and sun) are nearly at a right angle to the earth; the moon is then in quadrature in its first quarter or last quarter
Those points or moments at which a half moon is visible More generally, it is the situation of two heavenly bodies when their longitudes differ by 90° [36] (tycho brahe)
1 The state of being separated in phase by 90° (p/2 radians) 2 Pertaining to the phase relationship between two periodic quantities varying with the same period, that is, with the same frequency or repetition rate, when the phase difference between them is one-quarter of their period
A means of combining errors or noise by summing the "square" of the values and then taking the "square root"
The position of the Moon or a planet when it is at right angles to the Sun The Moon is in first quarter phase when it is in east quadrature to the Sun and last quarter phase when it is in west quadrature
When a superior planet; Jupiter, Saturn etc ; is at right angles to the Sun, as seen from Earth
A technique that separates signal channels by 90ø (electrical) in feedback devices It is used with encoders and resolvers to detect direction of motion
Quadrature is the term for two identical periodic signals when the phase displacement is nominally 90 electrical degrees
when a superior planet appears at right angles to the Sun as seen from the Earth
The integral used in obtaining the area bounded by a curve; hence, the definite integral of the product of any function of one variable into the differential of that variable
