question 317

Multiple Choice

Solve the problem.
-Given that the polar equation $\mathrm { r } = \frac { \mathrm { a } \left( 1 - \mathrm { e } ^ { 2 } \right) } { 1 + \mathrm { e } \cos \theta }$ models the orbits of the planets, compare Earth's orbit relative to the sun with that of Pluto and describe the difference. For Earth, $\mathrm { a } = 1.00$ and $\mathrm { e } = 0.017$ . For Pluto, $\mathrm { a } = 39.4$ and $\mathrm { e } = 0.249$ .

• A) Earth's orbit closely approximates a circle with the sun positioned at its center. Pluto's orbit is more elliptical with the sun positioned on its long axis about 10 astronomical units away from the center.
• B) Pluto's orbit closely approximates a circle with the sun positioned at its center. Earth's orbit is more elliptical with the sun positioned on its long axis about 10 astronomical units away from the center.
• C) Earth circles the sun, but Pluto does not.
• D) The orbits of Earth and Pluto are both circular, with the sun positioned at their centers, but the diameter of Pluto's orbit is about 40 times that of Earth.
