The question is a strange one as the answer depends on the context in which the question is asked. Graphically speaking: A line forming a perfect circle means that given a set point as the centre of the circle, the line will always be the exact same distance from the centre of the circle at any point along the line. An Ellipse on the other hand is a smooth closed curve that is symmetrical about its centre point, or by way of example, two points on the ellipse which are exactly opposite each other across the centre of the ellipse will each be exactly the same distance from the centre. Mathematically speaking, the difference can be defined by the equations (formulae) of each: A perfect Circle will have the equation: (x-a)2 + (y-b)2 = r2 for a circle with: a centre in Cartesian co-ordinates of (a,b)
a radius of r
An Ellipse will have the equation: (x2/a2) + (y2/b2) = 1 for an ellipse with: a maximum value in the X-axis of 'a' (+a or -a)
a maximum value in the Y-axis of 'b' (+b or -b) The essential difference in these equations can be seen if we consider an ellipse and a circle each with a centre of (0,0) in Cartesian co-ordinates. the equation for a circle would become: X2 + Y2 = r we can manipulate this equation by dividing both sides by 'r' to give X2/r + Y2/r = 1 the only difference now between the equation of the ellipse and this equation of a circle is that instead of allowing the 'r' X2/r to be different to the 'r' in Y2/r as in the case of an ellipse, both are kept the same.
Variable, as an ellipse is not a perfect circle.
ellipse is the shape of an egg
As the shape of an ellipse becomes more elongated, its eccentricity, which measures the deviation from being a perfect circle, increases. Eccentricity values range from 0 (a perfect circle) to 1 (a parabola). As the ellipse approaches a straight line, its eccentricity approaches 1, indicating a greater degree of elongation and deviation from circularity. Thus, the closer the ellipse is to resembling a straight line, the closer its eccentricity gets to 1.
Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse

A circle is an ellipse, so it's elliptical either way.However, the orbit of Mars is not a perfect circle.
No - The eccentricity only tells us the degree to which the ellipse is flattened with respect to a perfect circle.
The Earth's orbit around the sun is an ellipse, not a perfect circle. This means the distance between the Earth and the sun varies slightly throughout the year, causing the change in seasons. The orbit is slightly elliptical due to gravitational interactions with other celestial bodies and not a perfect circle.

An oval. Or an ellipse.

Yes; the circle is a special case of an ellipse.
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
