Usage Notes or Etymology
This word is derived from the Latin elongatio which means to move away. In an astronomical context, this term specifically refers to the angular separation between the Sun and another planet from the perspective of an observer on Earth. Technically, elongation determines the best time to observe inferior planets such as Mercury and Venus. When at its furthest point or maximum elongation, the planet will be at its highest position in the sky before sunrise or after sunset.
