the geocentric angle between a planet and the Sun, measured in the plane of the planet, Earth and Sun. Planetary elongations are measured from 0° to 180° , east or west of the Sun.

the geocentric angle between a satellite and its primary, measured in the plane of the satellite, planet and Earth. Satellite elongations are measured from 0° east or west of the planet.

The angular distance between two celestial bodies as seen from Earth.

The angular distance between the Sun and any other solar system body, or between a satellite and its parent planet. The greatest elongation of an inferior planet is its maximum angular distance from the Sun; at this time the planet sets ( greatest elongation east) or rises ( greatest elongation west) at the greatest time from sunset or sunrise. (See diagram.) For extended bodies (e.g. Sun, Moon, planets), the body's position is taken to be its centre.

Arc-angle between two celestial objects as measured from the earth.

Apparent angular distance of a member of the solar system from the sun as seen from the earth.

Particularly of Mercury and Venus, the apparent separation between the planet and the Sun. Maximum elongations alternate with conjunctions.

The angle between a planet (or other body) and the Sun, as measured from Earth. The maximum elongation for a superior planet is 180 degrees, this is known as opposition. For inferior planets maximum elongation is always less than 90 degrees. Maximum elongation is the best time to observe the inferior planets and opposition is the best time to observe the superior planets.

The angular distance separating any two or more celestial objects. Since Mercury and Venus are closer to the Sun than Earth, they never get very far from the Sun. Mercury's greatest elongation from the Sun is just 22 degrees. Venus' is somewhat greater at 46 degrees. By contrast, planets outside Earth's orbit reach solar elongations of 180 degrees when at opposition.

The angular distance between a planet and the sun.

The angular separation between two celestial bodies.

The angular distance between the Sun and any other solar system body, usually the Earth, expressed in degrees. The term Greatest Elongation is applied to the inner planets, Mercury and Venus. It is the maximum elongation from the Sun. At Greatest Elongation, the planet will appear 50% phase.

the apparent angular separation of an object from the sun

The angular distance of a planetary body from the Sun as seen from Earth. A planet at greatest eastern elongation is seen in the evening sky and a planet at greatest western elongation will be seen in the morning sky.

The angle between a planet and the Sun as seen from the Earth.

The distance of a planet from the Sun, as viewed from Earth. The maximum elongation for the inferior planets is 28° for Mercury, and 48° for Venus.

The Elongation of a planet is its angular separation between it and the sun as seen from the observer's position (usually Earth!).

The angular separation between the Sun and a solar system object as viewed by an observer (usually on the Earth).

The angle between a planet and the Sun in the sky. Because Mercury and Venus are inside the Earth's orbit, their elongation angles are never more than 23 degrees (for Mercury) or 46 degrees (for Venus), which is why they appear as "morning" or "evening" stars, never as "midnight stars." All other planets, though, with orbits outside the Earth's, can appear at any elongation angle. When a planet reaches the greatest angular separation east of west of the Sun in the sky, it is said to have reached greatest elongation. The maximum elongation for Venus and Mercury is 46 and 23 degrees, respectively. The maximum elongation of planets outside the orbit of the Earth is 180 degrees, when the planet is said to be at opposition. At these points in the sky, planets are visible for the longest period of time. See also: opposition

The angular separation between the Sun and a planet measured in angular units.

These terms are generally applied to Mercury and Venus. When seen from Earth, when either planet reaches its greatest angular distance from the Sun, they are said to have reached eastern (or western) elongation.

Distance of a planet, measured in degrees, from the Sun.

Elongation is an astronomical term that refers to the angle between the Sun and a planet, as viewed from Earth.
