it without difficulty saw that Judzhinii at all does not deliver pleasure to tell about threatening destruction of the Earth and if it constantly not to push questions, she there and then will become silent. About it told all: as it after each question of the daughter was a little removed from it as if aspired to escape as it slightly licked lips as if trying to erase from them traces of the words.But Marlena did not want, that mother has become silent. It was necessary for it the nobility more. She has cautiously asked:
- If Nemezida passes by, how it can destroy the Earth?
- I will try to explain. The Earth moves on a circumsolar orbit - in the same way, as the Rotor on an orbit round Eritro. If all Solar system consisted only of the Sun and the Earth the Earth would move on this orbit almost eternally. I have told "almost" because at movement the Earth radiates gravitational waves which reduce its moment of movement. Therefore the Earth slowly comes nearer to the Sun - however, so slowly, that this rapprochement almost in all cases can be neglected.
But round the Sun addresses not only the Earth, but also the Moon, Mars, Venus, Jupiter and other space bodies of system. All of them draw the Earth. Force of this attraction is insignificant in comparison with the Sun attraction so that the orbit of the Earth remains more or less a constant. As this attraction is weak, the direction and which force in process of movement of planets are changed very much with difficulty, nevertheless it changes an orbit of the Earth a little. The Earth that hardly comes nearer to the Sun hardly keeps away from it, the inclination of its axis and eccentricity of an orbit too are a little changed, and so on.
It is possible to show - and it has been shown, - that all these little changes periodically repeat. That is separate changes do not strengthen, and, on the contrary, counterbalance one another, In the end all it leads to that infringement of a circumsolar orbit of the Earth is influenced at least by ten various factors. The same concerns and orbits of other planets of Solar system. At such infringements of an orbit all life on the Earth is not destroyed. At worst they lead to a freezing or, on the contrary, to thawing of an ice cover and, thus, to fall or increase of level of the World ocean. All live transferred similar infringements of an orbit throughout three billions years. Now we will assume that by Solar system Nemezida will fly, without coming nearer to it less, than on the one tenth light year, that is approximately on billion kilometres. I was not precisely expressed, having told "will fly". Actually the neighbourhood of Nemezidy with Solar system will last some years. It will inform system a gravitational impulse and as a result orbits of planets will be infringed more seriously. Therefore, when Nemezida will depart, they again begin to be exposed to only small infringements.
