“Someone once said of this place that you can hear it listening to you.”
Jonathan White, Tides: The Science and Spirit of the Ocean
“When it’s farthest away, in apogee, it’s 253,000 miles from us, and the force is 16 percent less than average. This is a gradual change, hardly discernible from day to day but very much discernible at the extremes. To an observer on earth, even the size of the moon changes with this cycle.”
Jonathan White, Tides: The Science and Spirit of the Ocean
“Because of this, the moon is sometimes closer to the earth, exerting more gravitational influence, and sometimes farther away, exerting less (see figure above). When the moon is closest, in perigee, it’s 222,000 miles away, and the tidal force is 22 percent greater than average.”
