Question

Quizplus · Accepted Answer

The perihelion is the point in a planet's orbit where it is closest to the sun. The period is the time it takes for a planet to complete one orbit around the sun. The eccentricity is a measure of how elliptical (or stretched out) a planet's orbit is. The semi-major axis is the distance from the center of the sun to the farthest point in a planet's orbit. The aphelion is the point in a planet's orbit where it is farthest from the sun.
