Local Planet-Satellites
A Brief Introduction to the Many Worlds of our Sol-system
Earth
Earth (and also Mars) today spin at the same rate, or nearly the same rate, as before the breakup of c. -3147 BC, which also suggests that Earth and Mars (and likelyMercury as well) both rotated at about 24 hours per day before -3147.
"The spin of the Earth is decreasing currently. The international atomic clock, which determines the length of the day for Earth, has been adjusted by thirty seconds since 1972. The Earth's rate of rotation thus has slowed 30 seconds in 32 years -- about a second per year. This is certainly much more than the nanosecond deviations experienced with the occasional coronal mass ejection." #(Cook, Appendix B n4) The 7-degree angle that the Earth's orbit has (today) to Sol's equator (the 'ecliptic') -- the largest of any planet -- speaks to the fact that Earth was furthest removed from the vertical location of the other planets. |
The current orbital inclinations of the outer [dwarf stars Saturn, Uranus and Neptune] matches the expected vertical separations of the planets in c. -3147. #(Cook, Chapter 2) -- In fact, this may be the only way to make concrete scientific sense out of the current orbital inclinations of, not only the outer planets, but every heavenly body in our current Sol-system -- including our own planet Earth.
