Aphelia: meaning, definitions and examples
๐
aphelia
[ ษหfiหliษ ]
astronomy
Aphelia refers to the point in the orbit of a celestial body where it is farthest from the sun. This term is commonly used in astronomy to describe the elliptical orbit of planets and other celestial objects, such as comets and asteroids. The aphelion occurs at the opposite point of the perihelion, where the body is closest to the sun.
Synonyms
Examples of usage
- The aphelion of Earth occurs in July.
- Comets often have long orbits with a significant difference between their perihelion and aphelion.
- Understanding aphelia helps astronomers calculate various orbital dynamics.

Etymology
The term 'aphelia' is derived from the Greek words 'apo' meaning 'away from' and 'helios' meaning 'sun'. The construction of the word emphasizes the position of an object in orbit relative to the sun. The concept of aphelia has been important in the fields of astronomy and physics since ancient times, as astronomers sought to understand the movements of celestial bodies. The formal usage of these terms began to appear in the 17th century as scientific discoveries advanced. The connection between the word and its meaning remains a fundamental aspect of celestial mechanics, aiding in the calculation of orbital paths and distances in our solar system and beyond.
