We are used to the fact that the Moon is a satellite of the Earth. But will it always be so? According to the NASA’s EARTH MOON SYSTEM, our night light may sooner or later leave the Earth’s orbit and become an independent planet. In this case, the Earth will turn into a lifeless desert …
The moon is removing at a speed of about 3.8 cm per year. Since the Moon is at a distance of 3.85 × 1010 cm from the Earth, it is already seen perfectly, in terms of order of magnitude, that the Earth-Moon system is several billion years old.
EARTH MOON SYSTEM
As it is supposed, once there was a companion of Venus, but then “flew away” from it. After that conditions on Venus became unsuitable for life, despite the fact that it is an earth-type planet.
“The Moon also departs every year from the Earth, and once, apparently, if there are no reverse processes, it should leave the Earth”
According to the scientists, one space research is currently being conducted to find out whether the conditions of life on our planet will change if it loses its natural satellite, and how to prevent the worst scenario.
Now the Moon moves around the Earth in an orbit close to elliptical, counter-clockwise (if viewed from the North Pole) with an average speed of 1.02 kilometers per second. In fact, the motion of our natural satellite is a rather complex process, which is affected by various perturbations caused by the attraction of the Sun, planets and flattened Earth form.
In the same way, the number of days in a year can be calculated from the growth cycles in mollusks (Pannella 1976, Scrutton 1978) and stromatolites (Mohr 1975, Pannella et al., 1968) and the nature of sedimentation (Williams, 1997). All these measurements are consistent with the gradual slowing down of the Earth during the last 650 million years.
The clock, based on the above-described delay in the Earth’s rotation, gives an independent method of dating the geological layer throughout most of the fossil record. These data are not consistent with the young age of the Earth.
But even if we imagine that the Moon is no longer a satellite of the Earth, this will not turn our planet into a kind of lifeless Venus, as scientists believe.
Mercury was once a companion of Venus. “Calculations showed that it is possible that, however, do not prove that it was so”. In addition, the development of the Earth and Venus can not follow the same path, since in the Venusian atmosphere there is an increased content of the heavy isotope of hydrogen – deuterium.
“It may be due to the fact that there was a relatively large amount of water on Venus. When the water in the upper layers of the atmosphere was decomposed into hydrogen and oxygen, the light isotope of hydrogen escaped into space faster than heavy, and the observed anomaly appeared, the scientist says. Not the fact that there was liquid water on the surface of Venus, and not steam in the atmosphere, that is not the fact that it was not as hot there as it is now. ”

The magnitude of tidal friction depends on the location of the continents. In the past, the continents were located in such a way like tidal friction, and thus the speed of the Earth’s slowing down and removing the moon, had to be smaller. The rotation of the Earth slowed down for 2 seconds every 100 thousand years (Eicher 1976).
The speed of Earth’s rotation in the distant past can be measured. Corals leave after themselves skeletons, which reflect both the daily layers and annual cycles, so you can count the number of days in the year when the coral grew. Measurements on fossilized corals with an age of 180-400 may give a year duration of 381-410 days, with older corals indicating more days per year (Eicher 1976, Scrutton 1970, Wells 1963, 1970).
