Suppose a Planet Is Discovered That Revolves Around Its Sun $\times 10 ^ { 7 }$

Multiple Choice

Suppose a planet is discovered that revolves around its sun in an elliptical orbit with the sun at one focus. Its perihelion distance (minimum distance from the planet to the sun) is approximately 1.3 $\times 10 ^ { 7 }$ km, and its aphelion distance (maximum distance from the planet to the sun) is approximately 6.9 $\times 10 ^ { 7 }$ km. Approximate the eccentricity of the planet's orbit. Round to three decimal places.

A) 0.683
B) 5.308
