Multiple Choice

The Comet Borrelly has an elliptical orbit with an eccentricity of $e \approx 0.624$ .The length of the major axis of the orbit is approximately 5.83 astronomical units.Find a polar equation for the orbit.How close does the comet come to the sun

• A) \(\frac { 1.780 } { 1 - 1.624 \sin \theta }\) Closest point to the sun is \(\approx\) 1.096 astronomical unit.
• B) \(\frac { 1.780 } { 1 + \cos \theta }\) Closest point to the sun is \(\approx\) 1.096 astronomical unit.
• C) \(\frac { 0.624 } { 1 + 1.780 \sin \theta }\) Closest point to the sun is \(\approx\) 1.096 astronomical unit.
• D) \(\frac { 1.780 } { 1 + 0.624 \sin \theta }\) Closest point to the sun is \(\approx\) 1.096 astronomical unit.
• E) \(\overline { 1 - 1.624 \cos \theta }\) Closest point to the sun is \(\approx\) 1.096 astronomical unit.
