ellipse
An ellipse can be either a long cigar-type shape, or almost circular, depending on whether the eccentricity is large or small. The distance along the length is called the major axis, while the width is the minor axis.
The planets' orbits have small eccentricity, and the eccentricity of the Earth's orbit is 1/60 which is very close to a circle but with the Sun off-centre.
The distance is maximum and minimum at either end of the major axis, because the Sun is 2.5 million km off-centre, so the distance varies from 147.1 to 152.1 million km with an average of 149.6 million km.
The major axis of the ellipse is 2 x 149.6 million kilometres, while the minor axis is 2 x 149.58 million km, which is only very slightly less, so the orbit is 99.99% circular.
the shell shape makes it strong.
Spherical
The distance around a two dimensional shape is known as the perimeter of the shape. If the shape is circular, it may be refered to as a circumference.

The shape of every orbit is an ellipse.
Oval
An ellipse.
The Earth revolves around the sun in an elliptical (egg-shaped) orbit.
A circle?
The earth orbits around the sun in an elliptical path. It is too oblong to be considered circular orbit.
An ellipse.
The earth can not orbit it's self. Orbit means one body going around another.
The actual shape of the earth's orbit around the sun is horrendously complicated. Partly because the earth does not orbit the sun and also because the orbit is influenced by the the gravitational attraction of the other planets. The earth does not orbit the sun: the centre of mass of the earth-sun system is at one of the foci of an ellipse whose eccentricity is 0.0167. The eccentricity varies from 0.0034 to 0.058.
