SOLAR SYSTEM

Detailed explanation-1: -The eccentricity of a circle is zero. The eccentricity of an ellipse which is not a circle is greater than zero but less than 1. The eccentricity of a parabola is 1. The eccentricity of a hyperbola is greater than 1.

Detailed explanation-2: -An eccentricity value of e = 0 corresponds to a perfect circle, whereas e = 1 corresponds to a parabola, and e > 1 corresponds to a hyperbola.

Detailed explanation-3: -The eccentricity of an ellipse is between 0 and 1 because the distance from the fixed point on the plane has a constant ratio which is less than the distance from the fixed line in the plane.

Detailed explanation-4: -An eccentricity of zero is a circular orbit, between zero and 1 is elliptical, equal to one is parabolic, and greater than 1 is hyperbolic.
