Neither. Both ovals and circles are two-dimensional shapes. Earth is three-dimensional. Earth is what is called an oblate spheroid, meaning it is wider around the equator than it is from pole to pole.
The shape of the orbit of each planet is an ellipse. An ellipse is a geometric shape that is like a flattened circle. The Sun is located at one of the foci of the ellipse, not at the center.
The earth's orbit, like almost all orbits of heavenly bodies, is an ellipse.
The Earth makes an elliptical orbit around the Sun, not a circular orbit. The names Earth and Sun are proper names for our planet and star, so they usually get a capital letter. What is one complete orbit called? A "siderial period". And the time it takes: one year.
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.
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.

Orbits are shaped like an ellipse, with the star at the focus. An ellipse does not have a constant radius.
An ellipse.
The path of an object in orbit around another object. It's a "conical section", shaped like a circle, but "flattened" in one direction (a circle can be considered a special case of an ellipse). An ellipse has two focal points.
It is called an ellipse.
Common term is an oval Mathematical is an ellipse
That shape is called an 'oval' or an 'ellipse'.
Most things orbit in an elliptical pattern. There is a technical definition of an ellipse but between you and me it is an oval.
Ovoid means "seeming like an oval" or "egg-shaped."
The path is called an orbit, and it's shaped like an ellipse.
