A satellite is in an elliptical orbit around a planet P. It is observed that the velocity of the satellite when it is farthest from the planet is 6 times less than that when it is closest to the planet. The ratio of distances between the satellite and the planet at closest and farthest points is
(1) 1 : 6
(2) 1 : 2
(3) 3 : 4
(4) 1 : 3
