Dear Friends: The Earth travels around the Sun along an elliptic path. The mayor axis of this ellipse is not fixed. It rotates. Do you know the angular velocity of this movement? Do you know the angle between the mayor axis and the line joining the summer and winter solstice?
Thanks in advance. Regards, Achim Loske. Instituto de Fisica, UNAM A.P. 1-1010 Queretaro, Qro. Mexico Fax: 52 42 38 11 65 Phone: 52 42 38 11 64
