Аннотация:Abstract-This article shows how the external gravity force onthe core of the planet leads to the appearance of the magneticfield (MF) of the planet. How this force provides acceptableconditions for the existence of life. Natural phenomena, whichcan easily be explained using the proposedmechanism ofinteraction of planets, such as earthquakes, mountainformation, ocean currents, tides, time jumps, changes in theduration of the day, periodic Solar activity are considered.
