perigee
C2Formal, Technical
Definition
Meaning
The point in the orbit of the Moon or a satellite where it is nearest to the Earth.
The point in any orbit around a celestial body where the orbiting object is closest; by metaphorical extension, the lowest point or nearest approach in a non-astronomical context (e.g., in a relationship or career).
Linguistics
Semantic Notes
Primarily an astronomical/astronautical term. Its use outside these fields is rare and metaphorical. It is the antonym of 'apogee,' which is more commonly used metaphorically to mean a high point.
Dialectal Variation
British vs American Usage
Differences
No significant differences in definition or usage. Spelling is identical.
Connotations
In both varieties, the word carries strong technical/scientific connotations. The metaphorical use is understood but very uncommon.
Frequency
Equally low-frequency in both BrE and AmE, confined to technical discussions of orbits, spaceflight, and astronomy.

Usage
Context Usage
Business
Virtually never used.
Academic
Used in physics, astronomy, aerospace engineering, and related scientific papers and textbooks.
Everyday
Extremely rare. Might appear in news articles about a 'supermoon' (full moon at perigee) or satellite launches.
Technical
The primary domain of use. Critical for describing satellite orbits, orbital mechanics, and celestial events.
Examples
By CEFR Level
- The moon looks biggest when it is at perigee.
- Engineers adjusted the satellite's thrusters to raise its low perigee and ensure a stable orbit.
- The comet will be at its perigee next week, offering a unique viewing opportunity.
- The spacecraft's orbit decayed rapidly after its perigee dipped into the upper atmosphere.
- Metaphorically, the scandal marked the perigee of his political career, from which he never fully recovered.
Learning
Memory Aids
Mnemonic
Think: PERI-gee = PERIphery of the Earth (but as close as you can get on that periphery). Remember it as the opposite of 'apogee' (A = Away).
Conceptual Metaphor
PROXIMITY IS A LOW POINT / DISTANCE IS A HIGH POINT (e.g., 'Their relationship was at its perigee'). A specialized instantiation of the more common 'highs and lows' metaphor.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'перигей' – this is a direct cognate with the same meaning. The trap is in overusing the metaphorical sense, which is rarer in English than the metaphorical use of 'апогей' (apogee) is in Russian.
Common Mistakes
- Mispronouncing as /pəˈrɪdʒ.iː/ or /ˈpɜː.rɪ.dʒiː/.
- Confusing 'perigee' (closest to Earth) with 'perihelion' (closest to the Sun).
- Using 'perigee' to mean a high point (mixing it up with 'apogee').

FAQ
Frequently Asked Questions
No. While often associated with the Moon, 'perigee' applies to any object (satellite, spacecraft, etc.) orbiting the Earth. For orbits around other bodies, specific terms like 'perihelion' (Sun) or 'perilune' (Moon) are used.
While it would be understood as a metaphorical extension by educated listeners, it is very rare and stylistically marked. 'Nadir' or simply 'low point' are more conventional choices.
The direct astronomical opposite is 'apogee' (the farthest point from Earth in an orbit). Metaphorically, 'apogee', 'peak', 'zenith', or 'climax' can serve as opposites.
In British English: /ˈper.ɪ.dʒiː/ (PER-ih-jee). In American English: /ˈper.ə.dʒiː/ (PER-uh-jee). The primary stress is on the first syllable.
