What is the minimum eccentricity an elipse can have?

Answer 1

the minimum would be a zero.

and a eccentricity of zero would be a circle

because if it's a zero, you only have one point because there is no focal distance.

if you have only one point to connect, it would be a circle.

on the other hand,

the maximum would be one; a line.

because eccentricity is in a fraction/decimal form.

the person before me wrote 7.

that is not humanly possible,

because that would mean a fraction like 700/100.

and how can the focal distance be grater than the major axis?

Answer 2

1.000

An ellipse with eccentricity=0 is a circle. As the ellipse becomes longer and skinnier,

like a circle that's being flattened more and more, the eccentricity approaches ' 1 '.

Answer 3

It is currently less than 0.02. But it is not constant, it varies from a low of about 0.005 to a high of nearly 0.06 over a period of a little less than a half million years. None of these is far from circular but may have significant climatological effects (see Milankovitch cycles).

Answer 4

Zero, at this eccentricity the ellipse is a circle.

Answer 5

The square root of ( a squared plus b squared ), quantity divided by a, where a is the length of the semi-major axis and b is the length of the semi-minor axis.

Answer 6

When the two foci of an ellipse are at the same point, then the ellipse has zero eccentricity,

and is known as a "circle".

Answer 7

The minimum eccentricity an ellipse can have is 0, which occurs when the ellipse is a perfect circle. In this case, the foci coincide at the center of the ellipse, resulting in an eccentricity of 0.
