An ellipse.
Ellipse.
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.
The shape of a comet's orbit is called an ellipse. This shape is a sort of narrowed circle and comets move in this shape around the sun.
The earth orbits around the sun in an elliptical path. It is too oblong to be considered circular orbit.
The Sun does not orbit the planets. The planets orbit the Sun. The Sun is stationary with relation to the planets' motion. The Sun does, however, orbit the Milky Way galaxy, as do the planets and everything else in the galaxy.

There is no 'periodic' change in the earths orbit. The orbit is elliptical and over time (a great many years) becomes less so.
