A parabola has eccentricity 1, a hyperbola has eccentricity greater than 1.
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.
A : A circle is a closed figure with eccentricity 1. Similarly, ellipse is also a closed fig with eccentricity less than 1 and parabola with greater than 1.
The eccentricity of the Earth's orbit is currently about 0.0167; that rounds to zero.

A parabola has eccentricity 1, a hyperbola has eccentricity greater than 1.
The Earth's orbit has a low eccentricity of about 0.0167, which means it is close to being circular.
A circular orbit would have an eccentricity of 0, meaning the orbit is perfectly circular with no deviation. Eccentricity is a measure of how elongated an orbit is, ranging from 0 to 1, with 0 indicating a circle and 1 indicating a parabolic orbit.

No, most planets in our solar system have orbits with non-zero eccentricity. Eccentricity measures the deviation of an orbit from a perfect circle, with 0 being a perfect circle and 1 being highly elongated. For example, Earth has an eccentricity of about 0.017, while Mercury has a higher eccentricity of about 0.206.
Nepttune
Mercury has an orbital eccentricity most similar to the moon's orbital eccentricity, which is about 0.2056. Mercury's eccentricity is approximately 0.206.
As the eccentricity of a shape increases, the shape becomes more elongated or stretched out. For example, an ellipse with a higher eccentricity will look more like a stretched circle. In general, as eccentricity increases, the shape will deviate more from its original form and become more elongated.
It is called a circle.A circle is an ellipse with zero eccentricity.Incidentally, you probably meant "geometric figure".
Is it an invisible ellipse ... I can't see it
The highest possible value of eccentricity is 1. This occurs in a parabolic orbit, where the distance between the foci equals the length of the major axis.
