WebDec 4, 1990 · The Earth's rotation has slowed down by 47-thousandths of a second per day in the past 3,200 years, Dr. Kevin Pang of NASA's Jet Propulsion Laboratory, said in paper presented before the American Geophysical Union at an AGU meeting in San Francisco. That means, he said, a day in 1200 B.C. was 47/1000 second shorter than the present day. WebMar 6, 2024 · What happens though is that at a distance of roughly ${r}'=93.4 R_{earth}$ (595,700 Km) the Earth stops spinning. Beyond ${r}'=93.4 R_{earth}$ the equations predict that to conserve angular momentum the Earth has to start spinning backwards! This violates my gut intuition, and that of others, as to what would happen.
