Unformatted text preview: separated by a distance D , what is the period of the orbit as a function of M and D ? Problem 9 A satellite of the Earth has an elliptical orbit with semimajor and semiminor axes related by b = a/ 2, where a is the semimajor axis. Imagine drawing this ellipse in the xy plane, with the center of the ellipse (not the foci) at the orgin, and the semimajor axis along the xaxix. Calculate the ratio of the speed at perihelion (closest point of the orbit to earth) to the speed at the point of the orbit that intersects the yaxis, i.e. just above the center of the ellipse. 1...
