Object _____ is in retrograde motion.
Object _____ has a true anomaly at epoch of 180 degree.
Object _____ has its perigee south of the equatorial plane.
Object _____ has a line of nodes which coincides with vernal equinox directions.
Object _____ has an argument of perigee of 200 degree.
Object _____ could have been launched from Siberia without a plane change.
Object _____ was probably launched from somewhere on the equator.
Object _____ reaches the maximum latitude of 70 degree.
The equation of an object in Earth orbit is (in canonical unit)
r = 1.5/(1+0.5cosf ) DU
Calculate the time of flight from perigee to one end of the minor axis (E = 90 degree) and
the time of flight from the end of the minor axis out to apogee.
