A circle.
The eccentricity of an ellipse, denoted as ( e ), quantifies its deviation from being circular. It ranges from 0 to 1, where an eccentricity of 0 indicates a perfect circle and values closer to 1 signify a more elongated shape. Essentially, the higher the eccentricity, the more stretched out the ellipse becomes. Thus, eccentricity provides insight into the shape and focus of the ellipse.
The eccentricity of a conic section is a measure of its deviation from being circular. An eccentricity of 1 indicates a parabola, meaning the curve opens indefinitely and does not close back on itself, unlike ellipses (eccentricity less than 1) or hyperbolas (eccentricity greater than 1). Therefore, a conic section with an eccentricity of 1 represents a parabolic shape.
Eccentricity is a measure of the deviation of a conic section from being circular. Its value ranges from 0 to 1 for ellipses, where 0 represents a perfect circle and values approaching 1 indicate an increasingly elongated shape. For parabolas, the eccentricity is exactly 1, while for hyperbolas, the eccentricity is greater than 1.
As the shape of an ellipse approaches a straight line, its eccentricity increases and approaches 1. Eccentricity (e) is defined as the ratio of the distance between the foci and the length of the major axis; for a circle, it is 0, and for a line, it becomes 1. Thus, as an ellipse becomes more elongated and closer to a straight line, the numerical value of its eccentricity rises from 0 to nearly 1.
A circle has no eccentricity because it is a perfectly symmetrical shape. The eccentricity of a shape is a measure of how much its shape deviates from being a perfect circle, so for a circle, the eccentricity is always zero.
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.
The eccentricity of an ellipse, denoted as ( e ), is a measure of how much the ellipse deviates from being circular. It ranges from 0 (a perfect circle) to values approaching 1 (which represents a highly elongated shape). A lower eccentricity indicates a shape closer to a circle, while a higher eccentricity reflects a more elongated or stretched appearance. Thus, the eccentricity directly influences the overall shape and visual characteristics of the ellipse.
The eccentricity measures how far off the centre each focus is, as a fraction of the distance from the centre to the extremity of the major axis.
When the eccentricity of an eclipse increases, its shape becomes more elongated or elliptical. This means that the eclipse will appear less circular and more stretched out. The degree of elongation will depend on how much the eccentricity increases.

Eccentricity is affected primarily by the shape of an orbit, which is determined by the gravitational interactions between celestial bodies. Factors such as the mass of the objects involved, their distance from each other, and any perturbations from nearby bodies can influence the orbit's shape. Additionally, the initial velocity and angle at which an object is moving can also impact its eccentricity. In essence, eccentricity varies based on the dynamics of the system in which the orbiting body exists.
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
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.
A bodies eccentricity is a measure of how circular the orbit of that body is. Perfectly circular orbits have the lowest eccentricity, of 0, whereas orbits such as that of the dwarf planet Pluto are more eccentric. When there are multiple large bodies in an orbit, with smaller bodies orbiting multiple of these, the eccentricities of the smaller bodies are quite high.
