| **Compare at perihelion and aphelion the angular and linear velocities of a comet moving along an ellipse with an eccentricity of 1/3 and an eccentricity of 0.75.**

At perihelion, the linear velocity is twice, and the angular velocity is four times greater than at aphelion. At perihelion, the linear velocity is 7 times, and the angular velocity is 49 times greater than at aphelion.
