1-15 An extra-terrestrial object is found to be approaching Earth when its geocen- tric radius is 403000 km, its true anomaly is 151 deg, and its Earth-relative speed is 2.25 km. s-¹. Assuming that the Earth is approximated as an inertial reference frame and that the gravitational parameter of the Earth is µ = 398600 km³ s-2, determine the following quantities related to the orbit of the object relative to the Earth: (a) The eccentricity. (b) The periapsis altitude. (c) The periapsis speed.
