Astrophysics Quote by Neil deGrasse Tyson
““This general flattening of objects that rotate is why Earth’s pole-to-pole diameter is smaller than its diameter at the equator. Not by much: three-tenths of one percent—about twenty-six miles.””
About This Quote
Source Speech: Cosmos Lecture, 2014
The Earth bulges at the equator because rotation flattens the poles, making the equatorial diameter slightly larger.
In simple terms: Earth is slightly wider at the equator due to spin.
