He explained that the division of the ancient Babylonians are based on the constellation of birth of the sun to determine which of the constellation. The earth around the sun, it is also the rotation occurs. As a result of the moon's gravity, the Earth's rotation during the shift will occur. In the past 3000 years, Earth has reached the offset angle of 30 degrees, so 12 hours should be the appropriate constellation of one month after the move. In addition, the astronomers also noted that when the ancient Babylonians first division of Constellation 13 Constellation, more that one for Ophiuchus.
