Two bodies are in quadrature when their difference in celestial longitude is 90 degrees. This is the position of a superior planet when its elongation is 90 degrees, east or west, depending on the direction of the planet from the sun.
Industry:Astronomy
Backward (westward) motion of the planet among the stars, resulting from the fact that it is viewed from the moving earth. It is the motion that a planet has when its right ascension is decreasing. Each year, when Earth passes a superior planet, such as Mars, the planet appears to move backward for a short time. It is the same effect you see when two trains are running in the same direction on side by side tracks. The slower train appears to be moving backward.

A celestial coordinate; it is the angular distance measured from the vernal equinox eastward along the celestial equator to the hour circle of a given star or other celestial body. It can be defined also as the arc of the celestial equator or the angle at the celestial pole between the hour circle of the vernal equinox and the hour circle of the body.
Industry:Astronomy
The point in a planet's orbit in which it is closest to earth. When viewing a planet it will appear on the opposite side of the sky as the sun. Two bodies are in opposition when the difference in celestial longitude is 180 degrees.
