(a) two hypothetical planets are moving about the sun in elliptical orbits having equal major axes. the minor axis of one, however, is half that of the other. how do the periods of the two planets compare? (b) the moon revolves about the earth in 27.3 days in an elliptical orbit whose semimajor axis is 60 times the earth’s radius. what would be the period of a satellite revolving close to the earth’s surface? (since the satellite is close to the earth’s surface, let its semimajor axis be the earth’s radius, r.)
