SOLAR SYSTEM

Detailed explanation-1: -A circle is an ellipse in which both the foci coincide with its center. As the foci are at the same point, for a circle, the distance from the center to a focus is zero. This eccentricity gives the circle its round shape. Thus the eccentricity of any circle is 0.

Detailed explanation-2: -The summary on the eccentricity of different conic sections is given below: Eccentricity of Circle = 0 (i.e.) e =0. Eccentricity of Line = Infinity (i.e.) e =1.

Detailed explanation-3: -An eccentricity of zero means that the orbit is a perfect circle, while an eccentricity of one means that the orbit is a line.

Detailed explanation-4: -One can think of the eccentricity as a measure of how much a conic section deviates from being circular. In particular: 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.

Detailed explanation-5: -Different values of eccentricity make different curves: At eccentricity = 0 we get a circle. for 0 < eccentricity < 1 we get an ellipse. for eccentricity = 1 we get a parabola.

Detailed explanation-6: -The eccentricity of a circle is zero. The directrix of a conic section is the line that, together with the point known as the focus, serves to define a conic section.
