runaway star
C1/C2Technical (astronomy), Figurative (journalistic, literary)
Definition
Meaning
A star moving through space at an unusually high velocity compared to surrounding stars, typically due to gravitational ejection from a binary system or a supernova explosion.
In figurative use, someone or something that achieves extraordinary success, prominence, or growth far beyond expectations, often suddenly. Can also imply something moving or developing very fast and in an uncontrolled manner.
Linguistics
Semantic Notes
The primary meaning is astronomical. The figurative meaning builds on the sense of high speed and a departure from the expected/controlled 'orbit' (e.g., of a career, a project, a situation).
Dialectal Variation
British vs American Usage
Differences

Connotations
Technical: neutral. Figurative: usually positive (massive success) but can carry a negative nuance of being out of control or defying normal constraints.
Frequency
Low in everyday speech. High within astronomy. Figurative use is occasional in quality journalism and business writing.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation 'убежавшая звезда' – this is nonsensical for the astronomical term. Use 'звезда-беглянка' or 'скоростная звезда'. Figuratively, it's closer to 'восходящая звезда' (rising star) but with more explosive speed and success.
Common Mistakes
- Confusing with 'shooting star' (meteor).
- Using 'runaway' as a verb (*The star runaway from the cluster).
- Using the indefinite article 'a' with the figurative sense applied to a specific, known person ('He is a runaway star of physics' is ok; 'He is *the runaway star...' is more idiomatic if he is uniquely prominent).

FAQ
Frequently Asked Questions
The primary mechanism is gravitational ejection from a binary star system, often triggered by the supernova explosion of the companion star.
Yes, figuratively. It describes a person (e.g., an actor, athlete, CEO) who rises to fame or success with exceptional and seemingly uncontrollable speed.
They are related. A runaway star is moving at high speed within a galaxy. A rogue star is a star not gravitationally bound to any galaxy, often a runaway star that has been ejected entirely.
No, it's a low-frequency term. It is specialist in astronomy and used occasionally in figurative, journalistic language.
