________________ Moreover, on the same night (15th of the bright half of Phalgun) the Moon appears in the beginning on the eastern horizon where the stars of the Great Bear also appear; but the Moon takes two hours to go where the Great Bear is. Thus the Great Bear is two hours in advance of the Moon.. Also on the same day (Ph. 15. bright half) at mid-night the Moon and the Great Bear.appear over our heads quite in the middle of the sky. What is the reason for this ? Really, if the Moon appears going to the west from the east because of the day to day rotation of the earth on its axis, then how can we say that change of place or position of the Great Bear is strange ? This is a point which requires consideration THE PROBLEM OF THE REVOLVING OF THE MOON: If the earth is believed to be a planet of the SC ir System and it is also said that the earth revolves round the sun with a velocity of 66,000 miles per hour. In the same way the Moon is also a satellite of the earth. The Moon revolves arounds the earth with a velocity of 2000 to 2100 miles per hour whereas the earth revolves round the Sun with a velocity of 66,000 miles per hour. In this case the velocity of the Moon is quite negligible! And yet the Moon can revolve fully around the earth. This is really surprising ! Never mind! It does not matter ! The Moon and the earth come opposite to each other on the 7th, 8th or 9th day of black half of every month on the orbit of the earth. And yet why do they not collide with each other ? According to the belief of the modern scientists the average distance between the Moon and the earth is about 2,30,000 miles. Now the orbit of the earth is equal to its diameter (7926 miles). That is, about 8000 miles. The Moon takes 4 hours to go over this orbit at the velocity of 2000 to 2100 miles per hour. (7926\2100 = 3 hour,30 minutes, 30 seconds ) During those four (16) www.jainelibrary.org For Private & Personal Use Only Jain Education International
