yörüngesindeki

Yörüngesindeki is a Turkish term that functions as an adjective meaning “in its orbit” or “orbiting,” used to describe objects that are located within the orbit of a celestial body. It is formed from yörünge (orbit) plus the possessive suffix si (its) and the locative-relativizer ndaki, yielding a phrase that can modify a following noun, as in yörüngesindeki uydular.

Morphology and nuance: The base yörünge provides the root meaning orbit. The suffix -si marks possession (“its orbit”), and -ndaki combines the locative meaning “in/within” with a relative function to indicate “the one that is in its orbit.” This construction allows speakers to specify that something lies in the orbit belonging to a previously mentioned body (for example, the Sun or the Earth). By contrast, yörüngedeki (without the possessive -si) simply means “in the orbit” and is used more generally to describe anything currently located in that orbit, without emphasizing ownership.

Usage: The term is common in astronomy, space science, and related writing. Examples include: “Dünya'nın yörüngesindeki uydular” (the satellites in Earth’s orbit) and “Güneş'in yörüngesindeki gezegen” (a planet in the Sun's orbit). It can also appear in more general or figurative language to describe objects or concepts associated with a particular orbital path.
