Saturn moves in an elliptical orbit with the sun at one of the foci. The length of the half of the major axis is 1,433,448,036 kilometers, and the eccentricity is 0.0557. Find the minimum distance (perihelion) of Saturn from the sun. Round your answer to nearest kilometer.
A) 1,462,116,997 km
B) 1,353,604,980 km
C) 1,404,779,075 km
D) 1,513,291,092 km
E) 79,843,056 km

Quizplus · Accepted Answer

The perihelion distance is calculated as a(1-e), where a is the semi-major axis and e is the eccentricity. Substituting the given values: 1,433,448,036 km * (1 - 0.0557) = 1,353,604,980 km.
