Polar Equations of Conics Can Be Used to Describe the Motion

question 17

Multiple Choice

Polar equations of conics can be used to describe the motion of comets. These paths can be graphed using the following polar equation, where e is the eccentricity of the conic and r _per is the perihelion distance measured in AU. The orbit of Saturn has r _per = 9.006 and e = 0.056. The motion of Comet 1973.99 has r _per = 0.142 and e = 2.718282. Graph both the motion of the comet and the orbit of Saturn.
