A satellite has these orbital elements: -- semi-major axis = 10,900 km -- eccentricity = 0.05 -- inclination = 60 degrees -- longitude of the ascending note = 175 degrees -- argument of perigee = 90 degrees -- true anomaly = 90 degrees a. Is this a direct or retrograde orbit? Why? b. Where is the satellite located in its orbit? c. Is perigee in the northern or southern hemisphere? Why? d. Is this a circular, elliptical, parabolic, or hyperbolic orbit? Why?
