Sentences with phrase «eccentricity cycle»
The phrase "eccentricity cycle" refers to a pattern or cycle that occurs in the orbit of a planet, where the shape of its orbit changes over time. This change in shape affects its distance from the sun, resulting in variations in temperature and climate on the planet over a long period. Full definition
