Because of the observations of the movement of the planets and the calculations based on these observations, we very accurately know the speed and direction of movement of the earth around the sun at any time, the phenomenon of aberration other than the fact that it proves the reality of movement of the earth around the sun, ismainly for determining the speed of light.
can imagine what impression must have made this definition then the speed of light, the result of which is very close match with the result of the measurement of the speed of Olaf Roemer, derived from observations of the repetition of eclipses of Jupiter's moons.It is necessary also to note that, in determining the speed of light from the oscillation period of revolution of Jupiter's moons influence the speed of the earth expressed in the direction of the line of sight, whereas the determination of the speed of the aberration phenomenon, the movement of the earth is perpendicular to the direction of the beam zreniya.Esche in antiquitypeople know that the moon is in the sign of the zodiac, the Moon in Gemini, Moon in Libra ....
further improvement of the telescope and measurement methods led to the fact that, in addition to movement of the earth around the sun, we must take into account the still othersobserver moving with the tube, and, consequently, occurring due to these movements aberration phenomenon.First of all, you must take into account the rotation of the earth around its osi5 then the movement of the earth around the common center of gravity in the system consisting of the earth and the moon, and finally, is estimated as a hypothesis, our entire planetary motion;prostranstve.Astrologiya system in ancient times: the Moon ...
rate at which the observer moves at the equator during the earth's rotation around its axis, a little less than one-sixtieth part of the average rate at which the earth moves around the sun.The rate at which the earth describes a small orbit for a month while moving around the common to her and the moon's center of gravity, which is equal to about 13 meters per second, barely one-thirtieth part of the high speed with which the earth's rotation around the axis, and which decreases in the direction ofthe poles.
However, very accurate measurements can not be neglected either of the other value.
