Apheli

Apheli is a term with no single, widely accepted definition in English. It is rarely used as a standalone word, but appears in a few contexts as a root form in technical vocabulary or as a proper name.

In astronomy, the related terms are aphelion and aphelian; apheli is not a standard word by itself in English and is not used to denote the orbital concept on its own. The standard term for the point in an orbit farthest from the Sun is aphelion, with aphelian used to describe things relating to aphelion.

In French, aphélie (with an accent) is the equivalent word for aphelion. Other languages have similar terms derived from the same roots.

Outside science, apheli can be encountered as a proper noun—used as a fictional place name, a character name, or a brand—distinct from the scientific term. Such uses are context-dependent and not related to orbital mechanics unless explicitly stated.
