..... Click the link for more information. was about 25 percent faster than it is now, giving the planet an 18-hour day, said Sonett.
The moon, now 240,000 miles away, was then closer to the Earth, he said, and the lunar month was only 25 days, compared to the present 29.5 days. Sonett said the moon is receding from the Earth at the rate of about 1-1/2 inches a year.
This affects the lunar month, which is the time it takes the moon to orbit the Earth and the period from one full moon to the next. As the moon's orbit grows, the lunar month lengthens."
So the supermoon of yesterday was the actual moon about [63800km (average distance) -57257km (perigee)=6543km and 6543km/3.82cm=] 171282720 years ago?[1][2][3][4][5][6]
