orbit
B2Formal/Technical in scientific contexts; extended meanings are neutral.
Definition
Meaning
The curved path, typically elliptical, of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution.
The regular, repeated course or scope of an activity, influence, or range of experience; a sphere of activity or influence. Also used as a verb meaning to move in a curved path around a celestial body or object.
Linguistics
Semantic Notes
The word maintains a strong association with astronomy and space travel, even in metaphorical use. Its sense of 'sphere of influence' derives from the idea of a celestial body's gravitational dominance over objects within its orbital path.

Memory Aids
Mnemonic
Imagine an ORB (a sphere) taking a specific path or route (IT) around another object – that's its ORB-IT.
Conceptual Metaphor
INFLUENCE/ATTRACTION IS GRAVITY; A SPHERE OF ACTIVITY IS AN ORBIT. (e.g., 'He operates in the orbit of powerful people.')
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'орбита' when used figuratively for a career path or life course, as English 'orbit' implies a cyclical/repeating path around a central influence, not a forward trajectory.
- Do not directly translate 'на орбите' as 'on orbit' for 'on duty/shift' (e.g., космонавт на орбите). Use 'on a mission' or 'in space'.
Common Mistakes
- Using 'orbit' as a synonym for any 'path' or 'journey' without the sense of revolution around a centre. (Incorrect: 'The car's orbit down the mountain road.')
- Confusing 'orbit' (revolving around) with 'rotate' or 'spin' (turning on an axis). The Earth rotates on its axis and orbits the Sun.
