Want this question answered?
The eccentricity of that ellipse is 0.4 .
No - The eccentricity only tells us the degree to which the ellipse is flattened with respect to a perfect circle.
It is called a circle.A circle is an ellipse with zero eccentricity.Incidentally, you probably meant "geometric figure".
What does eccentricity means? But a ellipse is a word i dunno, all i know is the ecllispe the minty mint i eat every day.
Eccentricity as it relates to an ellipse is the ratio of the major and minor axes of the ellipse.Since it's the ratio of two distances, it winds up being dimensionless, i.e. only a number, with no units.Example: What's the ratio of a dozen eggs to four eggs ? The ratio is 3 . . . no dimensions, just 3.
Eccentricity does not refer to the [size] of the ellipse. It refers to the [shape].An ellipse with [zero] eccentricity is a [circle].As the eccentricity increases, the ellipse becomes less circular,and more 'squashed', like an egg or a football.
The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
The two fixed points are the foci but these do not define the shape of the ellipse. You also need to know the eccentricity.
An ellipse whose eccentricity is zero is a circle. As its eccentricity increases, it becomes more and more elliptical, i.e. its foci move farther apart and it appears more "egg-shaped".
A circle
The eccentricity of that ellipse is 0.4 .
the eccentricity will increase.
Mercury's orbit, like all planet's, is elliptical.The eccentricity of Mercury's orbit is 0.206

Eccentricity is only present in ovals and ellipses. A circle is present. The eccentricity of an oval or ellipse is how linear it is.
If the eccentricity was 0 the ellipse would instead be a circle, and if the eccentricity was 1 it would be a straight line segment.
